Verification of the Deutsch-Schorr-Waite Marking Algorithm with Modal Logicograms. In this paper, the method is applied to verify the correctness of the Deutsch-Schorr-Waite marking algorithm, which is regarded as a benchmark of such analysis. Both the partial correctness and the termination are discussed. For the former, we built a system on top of the proof assistant Agd

CLEFT

Bounded Verification of Voting Softwareed within a finite space given by a bound on the size of the heap and the number of loop unrollings. The technique involves an encoding of the procedure in an intermediate relational programming language, a translation of that language to relational logic, and an analysis of the logic that exploits

Expression Decomposition in a Rely/Guarantee Contextsion evaluation. This decomposition provides a means of addressing the fact that the logical meaning of expressions relative to a single state and the semantic evaluation of expressions in a fine-grained concurrent language do not provide the same results; in particular, the former results in a sing

A Verification Approach for System-Level Concurrent Programspractically used programming languages such as C . a realistic model of concurrency, i.e. a model that copes with the granularity of atomic operations actually used in a target machine..Our approach serves as the foundation for the verification of concurrent programs in C0 – a C fragment enriched by

Flexible Immutability with Frozen Objectss. However, class-based approaches are restrictive because programmers can neither make instances of arbitrary classes immutable, nor can they control when an instance becomes immutable. These restrictions prevent many interesting applications where objects of mutable classes go through a number of
