Optimization of checking the feasibility of transitions when verifying formal models

A.V. Kolchin


Transitions feasibility analysis becomes a significant part of operation time of verification tools for formal models of programs, which control flow is expressed implicitly. This paper describes a new method of model checking performance improvement. The main idea is a localization of a transition’s unsatisfiability reason in some state and it’s usage for the satisfiability analysis in subsequent states.
