Abstract

Given a finite set of concurrent processes executing asynchronously, such that each process may use randomization in its course of execution, we consider the problem of computing the worst-case probability for the program which consists of these processes to terminate (i.e, to converge to a specified set of common goal states), under a fair interleaving scheduling of the processes. Several methods for computing this probability are presented, and characterizations of the special case in which this probability is 1 are derived. Specializations of these characterizations to the case of deterministic and nondeterministic programs are also discussed.
