Techniques for Distributed Reachability Analysis with Partial Order and Symmetry based Reductions

Abstract

In this work we propose techniques for efficient reachability analysis of the state space (e.g., detection of bad states) using a combination of partial order and symmetry based reductions in a distributed setting. The proposed techniques are focused towards explicit state space enumeration based model-checkers like SPIN. We consider variants for both depth-first as well as breadth-first based generation of the reduced state graphs on-the-fly.
