Abstract

One of the most important open problems of parallel LTL model-checking is to design an on-the-fly scalable parallel algorithm with linear time complexity. Such an algorithm would give the optimality we have in sequential LTL model-checking. In this paper we give a partial solution to the problem. We propose an algorithm that has the required properties for a very rich subset of LTL properties, namely those expressible by weak Büchi automata.
