Abstract:

A confluent process (of a given transition system G) is an acyclic confluent transition system that is a `partial unfolding' of G. Intuitively, it represents a concurrent run of G. Given a non-confluent G, how to find maximal confluent processes of G is a theoretical problem having many practical applications.

In this talk we propose an unfolding procedure for extracting maximal confluent processes from transition systems. The key technique we utilize in the procedure is the construction of granular configuration structures (i.e. a form of event structures) based on diamond structures inside transition systems.
