This theorem no longer holds when the system is extended with Peano's axioms to give a formalisation for arithmetic. The problem of generalisation results, since arbitrary formulae can be cut in. This makes theorem-proving very difficult - one solution is to embed arithmetic in a stronger system, where cut elimination holds. This paper describes a system based on the omega rule, and shows that certain statements are provable in this system which are not provable in Peano arithmetic without cut. Moreover, an important application is presented in the form of a new method of generalisation by means of "guiding proofs" in the stronger system, which sometimes succeeds in producing proofs in the original system when other methods fail. The implementation of such a system is also described.} }

The key idea of this method is that extremely large sets can often be efficiently represented with propositional formulas. Most tools implement these formulas by means of binary decision diagrams (BDDs), which have therefore become a key data structure in modern VLSI CAD systems. Some board games like American checkers have a state space whose size is well within the range of state space sizes that have been tackled by symbolic model checking. Moreover, the question whether there is a winning strategy in these games can be reduced to two simple $\mu$-calculus formulas. Hence, the entire problem to solve such games can be reduced to simple $\mu$-calculus model checking problems. In this paper, we show how to model American checkers as a finite state system by means of BDDs. We moreover specify the existence of winning strategies for both players by simple $\mu$-calculus formulas. Further still, we report on our experimental results with our own model checking tool, and we describe some powerful improvements that we have found in trying to solve the game.} }

Such specifications differ from the common case in which any given input is specified to have exactly one correct output. Our approach is based on symbolic simulation with binary decision diagrams, and involves two distinct steps. First, we prove a lemma that reduces the relative error specification to several inequalities that involve reasoning about natural numbers only. The most complex of these inequalities asserts that the product of several naturals is less-than/greater-than another natural. Second, we invoke one of several customized algorithms that decides the inequality, without performing the expensive symbolic multiplications directly. We demonstrate the effectiveness of our approach on a next-generation Intel processor design and report encouraging time and space metrics for these proofs.} }

First, the possible variations in system parameters and operating conditions are encoded with Boolean variables. Then the system is evaluated for all variations by a sequence of OBDD operations.

Programming languages can succeed or fail based on the breadth and quality of their library collection. Over the last few years, the Haskell community has risen to the task of building the library infrastructure necessary for Haskell to succeed as a programming language suitable for writing real-world applications. This on-going work, the Cabal and Hackage effort, is built on the open source model of distributed development, and have resulted in a flowering of development in the language with more code produced and reused now than at any point in the community's history. It is easier to obtain and use Haskell code, in a wider range of environments, than ever before. This demonstration describes the infrastructure and process of Haskell development inside the Cabal/Hackage framework, including the build system, library dependency resolution, centralised publication, documentation and distribution, and how the code escapes outward into the wider software community. We survey the benefits and trade-offs in a distributed, collaborative development ecosystem and look at a proposed Haskell Platform that envisages a complete Haskell development environment, batteries included.} }

Android's application model is designed to encourage applications to share their code and data with other applications.

In this paper we present SCanDroid, a tool for reasoning automatically about the security of Android applications. SCanDroid's analysis is modular to allow incremental checking of applications as they are installed on an Android device. It extracts security specifications from manifests that accompany such applications, and checks whether data flows through those applications are consistent with those specifications. To our knowledge, SCanDroid is the first program analysis tool for Android, and we expect it to be useful for automated security certification of Android applications.} }

Examples include Alf, Automath, Coq, Ehdm, HOL, IMPS, Lambda, LEGO, Nuprl, PVS and Veritas. For many applications type theory works well and provides, for specification, the benefits of type-checking that are well-known in programming. However, there are areas where types get in the way or seem unmotivated. Furthermore, most people with a scientific or engineering background already know set theory, whereas type theory may appear inaccessable and so be an obstacle to the uptake of proof assistants based on it. This paper describes some experiments (using HOL) in combining set theory and type theory; the aim is to get the best of both worlds in a single system. Three approaches have been tried, all based on an axiomatically specified type V of ZF-like sets: (i) HOL is used without any additions besides V; (ii) an embedding of the HOL logic into V is provided; (iii) HOL axiomatic theories are automatically translated into set-theoretic definitional theories. These approaches are illustrated with two examples: the construction of lists and a simple lemma in group theory.} }

The goal is to provide a platform for implementing intimate combinations of deduction and algorithmic verification, like model checking. The first programming method uses a small kernel of ML functions to convert between BDDs, terms and theorems. It is easy to use and is suitable for rapid prototying experiments. The second method requires lower-level programming but can support more efficient calculations. It is based on an LCF-like use of an abstract type to encapsulate rules for manipulating judgements r t -> b meaning ``logical term t is represented by BDD b with respect to variable order r''. The two methods are illustrated by showing how to perform the standard fixed-point calculation of the BDD of the set of reachable states of a finite state machine.} }

This allows algorithms based on binary decision diagrams (BDDs) to be programmed as derived proof rules in a calculus of representation judgements. The derivation of representation judgements becomes an LCF-style proof by defining an abstract type for judgements analogous to the LCF type of theorems. The primitive inference rules for representation judgements correspond to the operations provided by an efficient BDD package coded in C (BuDDy). Proof can combine traditional inference with steps inferring representation judgements. The resulting system provides a platform to support a tight and principled integration of theorem proving and model checking. The methods are illustrated by using them to solve all instances of a generalised Missionaries and Cannibals problem.} }

The goal is to see if it is feasible to implement useful tools that work directly from the official semantics by mechanised proof. Such tools will have a high assurance of conforming to the standard. We have implemented two experimental tools: an interpreter that evaluates whether a finite trace $w$, which may be generated by a simulator, satisfies a PSL formula $f$ (i.e.~$w \models f$), and a compiler that converts PSL formulas to checkers in an intermediate format suitable for translation to HDL for inclusion in simulation test-benches. Although our tools use logical deduction and are thus slower than hand-crafted implementations, they may be speedy enough for some applications. They can also provide a reference for more efficient implementations.} }

Some important systems of real-valued propositional and predicate calculus are defined and investigated. The aim is to show that fuzzy logic as a logic of imprecise (vague) propositions does have well-developed formal foundations and that most things usually named `fuzzy inference' can be naturally understood as logical deduction. There are two main groups of intended readers. First, logicians: they can see that fuzzy logic is indeed a branch of logic and may find several very interesting open problems. Second, equally important, researchers involved in fuzzy logic applications and soft computing. As a matter of fact, most of these are not professional logicians so that it can easily happen that an application, clever and successful as it may be, is presented in a way which is logically not entirely correct or may appear simple-minded. (Standard presentations of the logical aspects of fuzzy controllers are the most typical example.) This fact would not be very important if only the bon ton of logicians were harmed; but it is the opinion of the author (who is a mathematical logician) that a better understanding of the strictly logical basis of fuzzy logic (in the usual broad sense) is very useful for fuzzy logic appliers since if they know better what they are doing, they may hope to do it better. In addition, a better mutual understanding between (classical) logicians and researchers in fuzzy logic, promises to lead to deeper cooperation and new results. Audience: mathematicians, logicians, computer scientists, specialists in artificial intelligence and knowledge engineering, developers of fuzzy logic.} }

We show that the two approaches can be easily combined, allowing us to reason in a straightforward way about statistical information and degrees of belief. We then consider axiomatizing these logics. In general, it can be shown that no complete axiomatization is possible. We provide axiom systems that are sound and complete in cases where a complete axiomatization is possible, showing that they do allow us to capture a great deal of interesting reasoning about probability.} }

Using techniques pioneered in Edinburgh LCF, this can be made palatable. However, some believe such an approach will never be efficient enough for large, complex proofs. One alternative, commonly called reflection, is to analyze proofs using a second layer of logic, a metalogic, and so justify abbreviating or simplifying proofs, making the kinds of shortcuts humans often do or appealing to specialized decision algorithms. In this paper we contrast the fully-expansive LCF approach with the use of reflection. We put forward arguments to suggest that the inadequacy of the LCF approach has not been adequately demonstrated, and neither has the practical utility of reflection (notwithstanding its undoubted intellectual interest). The LCF system with which we are most concerned is the HOL proof assistant. The plan of the paper is as follows. We examine ways of providing user extensibility for theorem provers, which naturally places the LCF and reflective approaches in opposition. A detailed introduction to LCF is provided, emphasizing ways in which it can be made efficient. Next, we present a short introduction to metatheory and its usefulness, and, starting from Gödel's proofs and Feferman's transfinite progressions of theories, look at logical `reflection principles'. We show how to introduce computational `reflection principles' which do not extend the power of the logic, but may make deductions in it more efficient, and speculate about their practical usefulness. Applications or proposed applications of computational reflection in theorem proving are surveyed, following which we draw some conclusions. In an appendix, we attempt to clarify a couple of other notions of `reflection' often encountered in the literature. The paper questions the too-easy acceptance of reflection principles as a practical necessity. However I hope it also serves as an adequate introduction to the concepts involved in reflection and a survey of relevant work. To this end, a rather extensive bibliography is provided.} }

The optimized size-bounded mode seems to be the overall winner, but for each strategy there are problems on which it performs best. Some attempt is made to analyze why. We emphasize that our optimization, and other implementation techniques like caching, are rather general: they are not dependent on the details of model elimination, or even that the search is concerned with theorem proving. As such, we believe that this study is a useful complement to research on extending the model elimination calculus.} }

But another important consideration, which we consider particularly significant, is the bias towards a `procedural' or `declarative' proof style. We will explore this choice in depth, and discuss the strengths and weaknesses of declarative and procedural styles for proofs in pure mathematics and for verification applications. We conclude with a brief summary of our own experiments in trying to combine both approaches.} }

While retaining the reliability and programmability of earlier versions, it is more elegant, lightweight, powerful and automatic; it will be the basis for the Cambridge component of the HOL-2000 initiative to develop the next generation of HOL theorem provers. HOL Light is written in CAML Light, and so will run well even on small machines, e.g. PCs and Macintoshes with a few megabytes of RAM. This is in stark contrast to the resource-hungry systems which are the norm in this field, other versions of HOL included. Among the new features of this version are a powerful simplifier, effective first order automation, simple higher-order matching and very general support for inductive and recursive definitions. Many theorem provers, model checkers and other hardware verification tools are tied to a particular set of facilities and a particular style of interaction. However HOL Light offers a wide range of proof tools and proof styles to suit the needs of various applications. For work in high-level mathematical theories, one can use a more `declarative' textbook-like style of proof (inspired by Trybulec's Mizar system). For larger but more routine and mechanical applications, HOL Light includes more `procedural' automated tools for simplifying complicated expressions, proving large tautologies etc. We believe this unusual range makes HOL Light a particularly promising vehicle for floating point verification, which involves a mix of abstract mathematics and concrete low-level reasoning. We will aim to give a brief tutorial introduction to the system, illustrating some of its features by way of such floating point verification examples. In this paper we explain the system and its possible applications in a little more detail.} }

Since the early 1990s two different kinds of endgame databases are publicly available, namely Edwards' so-called "tablebases" and Thompson's collection of 5-piece databases. Although Thompson's databases enjoy much wider international fame, most current chess programs use tablebases because they integrate far better with the rest of the search. For the benefit of all those enthusi- asts who intend to incorporate endgame databases into their own chess programs, this article describes the index schemes of Edwards' tablebases and Thompson's databases in detail, explains their differences, and provides a comparative evaluation of both. In addition we introduce new indexing methods that improve on the published state-of-the-art and shrink the respective index ranges even further (especially for large databases and endgames with Pawns). This reduces the overall space requirements of the resulting databases substantially. We also propose several solutions for the problem of potential en-passant captures in endgame databases with at least one Pawn per each side. Shortly after the initial submission of our original text, Nalimov independently applied similar techniques as ours and even more advanced index schemes to his new tablebases which are now publicly available on the Internet, too.

We begin with an extensive foundational development of probability, creating a higher-order logic formalization of mathematical measure theory. This allows the definition of the probability space we use to model a random bit generator, which informally is a stream of coin-flips, or technically an infinite sequence of IID Bernoulli(1/2) random variables. Probabilistic programs are modelled using the state-transformer monad familiar from functional programming, where the random bit generator is passed around in the computation. Functions remove random bits from the generator to perform their calculation, and then pass back the changed random bit generator with the result. Our probability space modelling the random bit generator allows us to give precise probabilistic specifications of such programs, and then verify them in the theorem prover. We also develop technical support designed to expedite verification: probabilistic quantifiers; a compositional property subsuming measurability and independence; a probabilistic while loop together with a formal concept of termination with probability 1. We also introduce a technique for reducing properties of a probabilistic while loop to properties of programs that are guaranteed to terminate: these can then be established using induction and standard methods of program correctness. We demonstrate the formal framework with some example probabilistic programs: sampling algorithms for four probability distributions; some optimal procedures for generating dice rolls from coin flips; the symmetric simple random walk. In addition, we verify the Miller-Rabin primality test, a well-known and commercially used probabilistic algorithm. Our fundamental perspective allows us to define a version with strong properties, which we can execute in the logic to prove compositeness of numbers.} }

For illustration, we verify in HOL two example probabilistic algorithms that necessarily rely on probabilistic termination: an algorithm to sample the Bernoulli(p) distribution using coin-flips; and the symmetric simple random walk.} }

They can also be used to support MLS policies on SELinux. However, the policies are very complex, and creating them is a difficult and error-prone process. Furthermore, it is not possible to state explicit constraints on an SELinux policy such as ``information flowing to the network must be encrypted''. We present two related Domain Specific Languages (DSL) to make it much easier to specify SELinux security policies. The first DSL is called Lobster. Lobster allows the user to state an information flow policy at a very high level of abstraction, and then refine the policy into lower and lower levels until it can be translated by the Lobster compiler into an SELinux policy. The second DSL is called Symbion. Symbion allows the user to state policy constraints such as ``information flowing to the network must be encrypted''. Symbion and Lobster will then interface with tools that can check that the policy satisfies the constraints. We also present the analysis tool Shrimp, with which we are able to analyze and find errors in the SELinux Reference Policy. Shrimp is also the basis for our ongoing effort in reverse translating the Reference Policy into Lobster. Since Lobster and Symbion represent information flows and contraints on information flows, they are more broadly applicable than to just SELinux. We will point to some of the directions we wish to take Lobster and Symbion beyond SELinux.} }

The Z notation was used for documenting the system specification and part of the design, and the SPARK1 subset of Ada was used for coding. However, perhaps the most distinctive nature of the project lies in the amount of proof that was carried out: proofs were carried out both at the Z level-approximately 150 proofs in 500 pages-and at the SPARK code level-approximately 9,000 verification conditions generated and discharged. The project was carried out under UK Interim Defence Standards 00-55 and 00-56, which require the use of formal methods on safety-critical applications. It is believed to be the first to be completed against the rigorous demands of the 1991 version of these standards. The paper includes comparisons of proof with the various types of testing employed, in terms of their efficiency at finding faults. The most striking result is that the Z proof appears to be substantially more efficient at finding faults than the most efficient testing phase. Given the importance of early fault detection, we believe this helps to show the significant benefit and practicality of large-scale proof on projects of this kind.} }

We present our experience in performing the formal, machine-checked verification of the seL4 microkernel from an abstract specification down to its C implementation. We assume correctness of compiler, assembly code, and hardware, and we used a unique design approach that fuses formal and operating systems techniques. To our knowledge, this is the first formal proof of functional correctness of a complete, general-purpose operating-system kernel. Functional correctness means here that the implementation always strictly follows our high-level abstract specification of kernel behaviour. This encompasses traditional design and implementation safety properties such as the kernel will never crash, and it will never perform an unsafe operation. It also proves much more: we can predict precisely how the kernel will behave in every possible situation. seL4, a third-generation microkernel of L4 provenance, comprises 8,700 lines of C code and 600 lines of assembler. Its performance is comparable to other high-performance L4 kernels.} }

Type systems are hard to get right, and getting them wrong can lead to inconsistencies. Set theory can serve as the basis for a specification languuage without types. This possibility, which has been widely overlooked, offers many advantages. Untyped set theory is simple and is more flexible than any simple typed formalism. Polymorphism, overloading, and subtyping can make a type system more powerful, but at the cost of increased complexity,and such refinements can never attain the flexibility of having no types at all. Typed formalisms have advantages too, stemming from the power of mechanical type checking. While types serve little purpose in hand proofs, they do help with mechanized proofs. In the absence of verification, type checking can catch errors in specifications. It may be possible to have the best of both worlds by adding typing annotations to an untyped specification language. We consider only specification languages, not programming languages.} }

In this paper we present a scheme for automatic dependency analysis of verified software, which for each program checks that the collection of installed libraries is sufficient to guarantee its functional correctness. We illustrate the scheme with a case study of Haskell packages verified in higher order logic. The dependency analysis reduces the burden of maintaining verified Haskell packages by automatically computing version ranges for the packages they depend on, such that any combination provides the functionality required for correct operation.} }

Probabilistic predicate transformers extend that facility to programs containing probabilistic choice, so that one can in principle determine not only whether a program is guaranteed to establish a certain result, but also its probability of doing so. We bring together independent work of Claire Jones and Jifeng He, showing how their constructions can be made to correspond; from that link between a predicate-based and a relation-based view of probabilistic execution we are able to propose "probabilistic healthiness conditions", generalising those of Dijkstra for ordinary predicate transformers. The associated calculus seems suitable for exploring further the rigorous derivation of imperative probabilistic programs.} }

Using theorems as rewrite rules helps to simplify the subgoals that arise during a proof. LCF is an interactive theorem-prover intended for reasoning about computation. Its implementation of rewriting is presented in detail. LCF provides a family of rewriting functions, and operators to combine them. A succession of functions is described, from pattern matching primitives to the rewriting tool that performs most inferences in LCF proofs. The design is highly modular. Each function performs a basic, specific task, such as recognizing a certain form of tautology. Each operator implements one method of building a rewriting function from sim- pler ones. These pieces can be put together in numerous ways, yielding a variety of rewriting strategies. The approach involves programming with higher-order functions. Rewriting functions are data val- ues, produced by computation on other rewriting functions. The code is in daily use at Cambridge, demon- strating the practical use of functional programming.} }

This paper reports on our success in verifying the "core" transformations of the compiler -- those transformations over the sub-language of Cryptol that begin after "higher-order" aspects of the language are compiled away, and finish just before hardware or software specific transformations are exercised. The core transformations are responsible for aggressive optimizations. We have written an ACL2 macro that automatically generates both the correspondence theorems and their proofs. The compiler also supplies measure functions that ACL2 uses to automatically prove termination of Cryptol programs, including programs with mutually-recursive cliques of streams. Our verifying compiler has proved the correctness of its core transformations for multiple algorithms, including TEA, RC6, and AES. Finally, we describe an ACL2 book of primitive operations for the general specification and verification of encryption algorithms.} }

Session types statically enforce that client-server communication proceeds according to protocols. They have been added to several concurrent calculi, but few implementations of session types are available. Our embedding takes advantage of Haskell where appropriate, but we rely on no exotic features. Thus our approach translates with minimal modification to other polymorphic, typed languages such as ML and Java. Our implementation works with existing Haskell concurrency mechanisms, handles multiple communication channels and recursive session types, and infers protocols automatically. While our implementation uses unsafe operations in Haskell, it does not violate Haskell's safety guarantees. We formalize this claim in a concurrent calculus with unsafe communication primitives over which we layer our implementation of session types, and we prove that the session types layer is safe. In particular, it enforces that channel-based communication follows consistent protocols.} }

The Omega test is based on an extension of Fourier-Motzkin variable elimination to integer programming, and has worst-case exponential time complexity. However, we show that for many situations in which other (polynomial) methods are accurate, the Omega test has low order polynomial time complexity. The Omega test can be used to simplify integer programming problems, rather than just deciding them. This has many applications, including accurately and efficiently computing dependence direction and distance vectors.} }

Probability distributions form a monad, and the monadic definition leads to a simple, natural semantics for a stochastic lambda calculus, as well as simple, clean implementations of common queries. But the monadic implementation of the expectation query can be much less efficient than current best practices in probabilistic modeling. We therefore present a language of measure terms, which can not only denote discrete probability distributions but can also support the best known modeling techniques. We give a translation of stochastic lambda calculus into measure terms. Whether one translates into the probability monad or into measure terms, the results of the translations denote the same probability distribution.} }

The need for ``correct'' designs in safety-critical applications, coupled with the major cost associated with products delivered late, are two of the main factors behind this. In addition, as the complexity of the designs increase, an ever smaller percentage of the possible behaviors of the designs will be simulated. Hence, the confidence in the designs obtained by simulation is rapidly diminishing. This paper provides an introduction to the topic by describing three of the main approaches to formal hardware verification: theorem-proving, model checking and symbolic simulation. We outline the underlying theory behind each approach, we illustrate the approaches by applying them to simple examples and we discuss their strengths and weaknesses. We conclude the paper by describing current on-going work on combining the approaches to achieve multi-level verification approaches.} }

Previous attempts to resolve this tradeoff have resulted either in poor selection of models, or in fragility as the search becomes over-sensitive to the order of clauses, or in extreme slowness. Here we present a fresh approach, whereby most of the clauses for which a model is sought are treated as soft constraints. The result is a partial model of all of the clauses rather than an exact model of only a subset of them. This allows our system to combine the speed of maintaining just a single model with the robustness previously requiring multiple models. We present experimental evidence of benefits over a range of first order problem domains.} }

Vardi}, title = {Why Is Modal Logic So Robustly Decidable?}, number = {TR97-274}, institution = {Rice University}, month = apr, year = 1997, abstract = {In the last 20 years modal logic has been applied to numerous areas of computer science, including artificial intelligence, program verification, hardware verification, database theory, and distributed computing. There are two main computational problems associated with modal logic. The first problem is checking if a given formula is true in a given state of a given structure. This problem is known as the model-checking problem. The second problem is checking if a given formula is true in all states of all structures. This problem is known as the validity problem. Both problems are decidable. The model-checking problem can be solved in linear time, while the validity problem is PSPACE-complete. This is rather surprising when one considers the fact that modal logic, in spite of its apparent propositional syntax, is essentially a first-order logic, since the necessity and possibility modalities quantify over the set of possible worlds, and model checking and validity for first-order logic are computationally hard problems. Why, then, is modal logic so robustly decidable? To answer this question, we have to take a close look at modal logic as a fragment of first-order logic. A careful examination reveals that propositional modal logic can in fact be viewed as a fragment of 2-variable first-order logic. It turns out that this fragment is computationally much more tractable than full first-order logic, which provides some explanation for the tractability of modal logic. Upon a deeper examination, however, we discover that this explanation is not too satisfactory. The tractability of modal logic is quite and cannot be explained by the relationship to two-variable first-order logic. We argue that the robust decidability of modal logic can be explained by the so-called tree-model property, and we show how the tree-model property leads to automata-based decision procedures.} }

In the situation where a Hol user would normally employ the built-in function GEN\_REWRITE\_CONV, a function that directly produces a conversion of the desired functionality, this article demonstrates how producing the conversion in the form of a program text instead of as a closure can lead to significant speed-ups. The Hol system uses a set of 31 simplifying equations on a very large number of intermediate terms derived, e.g., during backwards proofs. For this set the conversion generated by the two-step method is about twice as fast as the method currently used. When installing the new conversion, tests show that the overall running times of Hol proofs are reduced by about 10\%. Apart from the speed-up this is completely invisible to the user.

Although intended for use in writing proof verification systems, OIL is an interesting general-purpose programming language. In some cases, very simple OIL programs can achieve an efficiency which requires a much more complicated algorithm in a traditional programming language. This thesis gives a formal semantics for OIL and some new results related to its efficient implementation. The main new result is a method of transforming bottomup logic programs with equality to bottom-up logic programs without equality. An introduction to OIL and several examples are also included.} }

As these theorem proving systems are usually very complex, it is extremely difficult if not impossible to formally verify them. This calls for an independent means of ensuring the consistency of mechanically generated proofs. This paper describes a method of recording HOL proofs in terms of a sequence of applications of inference rules. The recorded proofs can then be checked by an independent proof checker. Also described in this paper is an efficient proof checker which is able to check a practical proof consisting of thousands of inference steps.} }

Today, certification relies as much on evaluation of the software development process as it does on the system s properties. While the latter are preferable, the complexity of these systems usually makes them extremely difficult to evaluate. To explore these and related issues, the National Coordination Office for Information technology Research and Development asked the NRC to undertake a study to assess the current state of certification in dependable systems. The study is in two phases: the first to frame the problem and the second to assess it. This report presents a summary of a workshop held as part of the first phase. The report presents a summary of workshop participants presentations and subsequent discussion. It covers, among other things, the strengths and limitations of process; new challenges and opportunities; experience to date; organization context; and cost-effectiveness of software engineering techniques. A consensus report will be issued upon completion of the second phase.} }
