Software Model-Checking as Cyclic-Proof Search [article]

Takeshi Tsukada, Hiroshi Unno
2021 arXiv   pre-print
This paper shows that a variety of software model-checking algorithms can be seen as proof-search strategies for a non-standard proof system, known as a cyclic proof system.  ...  Our use of the cyclic proof system as a logical foundation of software model checking enables us to compare different algorithms, to reconstruct well-known algorithms from a few simple principles, and  ...  BASIC NOTIONS OF SOFTWARE MODEL-CHECKING The Goal Sequent As the first step to establish a connection between software model-checking and cyclic-proof search, this section describes the goal sequent  ...

ActionScript bytecode verification with co-logic programming

Brian W. DeVries, Gopal Gupta, Kevin W. Hamlen, Scott Moore, Meera Sridhar
2009 Proceedings of the ACM SIGPLAN Fourth Workshop on Programming Languages and Analysis for Security - PLAS '09  
Our experience with co-logic programming indicates that it is an extremely useful paradigm for elegantly expressing algorithms that lie at the heart of model-checking technologies.  ...  While important, these systems do not address certain significant practical issues, such as state space explosion, that typically arise when model-checking real software systems.  ...  LTL underpins many modern software model checking technologies, and allows us to conveniently draw upon existing techniques from the field.  ...

Small flag complexes with torsion [article]

As a consequence we confirm a folklore conjecture that the smallest poset whose order complex is homotopy equivalent to the real projective plane (and also the smallest poset with torsion in the first  ...  We now proceed with the proof of Theorem 2. Proof. This is an immediate brute-force computer check. Proof of Theorem 2.  ...  From this set we need to choose graphs with cyclic links. This condition is easily verified as follows.  ...

Non-intrusive Repair of Reactive Programs

David Harel, Guy Katz, Assaf Marron, Gera Weiss
2012 2012 IEEE 17th International Conference on Engineering of Complex Computer Systems  
Our repair algorithms apply model checking to the program and transform the counterexamples produced by the model-checker into corrective modules.  ...  Our work is supported by a proof-ofconcept tool, which creates understandable modules that can be further manually managed as part of ongoing incremental system development.  ...  The cyclic patching algorithm is as follows (G denotes the full state graph traversed by the model-checker): Cyclic Patching(P, Φ): Run the model checker on (P, Φ) if P ⊧ Φ then return P for each violating  ...

Satisfiability Modulo Heap-Based Programs [chapter]

Quang Loc Le, Jun Sun, Wei-Ngan Chin
2016 Lecture Notes in Computer Science  
In each iteration, it searches for a proof of either satisfiability or unsatisfiability. Our procedure is further enhanced with automatically inferred invariants as well as detection of cyclic proof.  ...  We have evaluated our system on benchmark programs from a software verification competition.  ...  If there is a cyclic proof of λ ind 0 , λ ind 0 is UNSAT. Proof We reduce our cyclic proof problem for satisfiability to the cyclic proof problem for entailment check, i.e., λ ind 0 false of CYCLIC.  ...

Lazy Annotation Revisited [chapter]

Kenneth L. McMillan
2014 Lecture Notes in Computer Science  
Lazy Annotation is a method of software model checking that performs a backtracking search for a symbolic counterexample.  ...  The resulting algorithm is compared both conceptually and experimentally to two approaches based on similar principles but using different learning strategies: unfolding-based Bounded Model Checking and  ...  Comparing LA with PDR on software model checking problems, we found that PDR's interpolation strategy as implemented in Z3 produced less effective learned annotations.  ...

At the same time, it is often useful to have an explicit proof that certifies the satisfiability. This is exactly what the certified model checking (CMC) has been introduced for.  ...  The standard model checking setup analyses whether the given system specification satisfies a dedicated temporal property of the system, providing a positive answer here or a counter-example.  ...  A model M is cyclic if it is a cyclic path.  ...

Non-cyclic Sorts for First-Order Satisfiability [chapter]

Konstantin Korovin
2013 Lecture Notes in Computer Science  
The non-cyclic fragment can be seen as a generalisation of the effectively propositional fragment (EPR) in the many-sorted setting.  ...  We show that the non-cyclic fragment is decidable by instantiation-based methods and present a linear time algorithm for checking whether a given clause set is in this fragment.  ...  Another explanation can be that in some cases searching for minimal models can still be quicker.  ...
