Abstract

In this work we deal with regular model checking which is a technique for analyzing programs whose state space can be infinite due to dealing with, e.g. unbounded queues, parameters, dynamically linked data structures, recursive procedures, or strings. The goal of this work was to implement improvements to the existing prototype tool ASMA implementing regular model checking over the Microsoft Automata library. We analysed the source code of ASMA and reran analyses of all available benchmark programs. We identified some bottlenecks and have tackled several of them. In particular, we integrated a library containing additional reduction algorithms into ASMA, created several new versions of the reverse concatenation operation, which tuned out to be very costly in the benchmarks, improved the command line interface of ASMA, and implemented some other optimizations for ASMA. The computation time was reduced by 90 % when analysing bigger programs.
