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.
