Improving Pushdown System Model Checking

Akash Lal and Thomas Reps

In this paper, we reduce pushdown system (PDS) model checking to a graph-theoretic problem, and apply a fast graph algorithm to improve the running time for model checking. Several other PDS questions and techniques can be carried out in the new setting, including witness tracing and incremental analysis, each of which benefits from the fast graph-based algorithm.
