This paper presents an efficient hash table based method to optimally overcome a new variant of the state space explosion which appears during the quasi-static task scheduling of embedded, reactive systems.

Our application domain is targeted to one-processor software synthesis, and the scheduling process is based on Petri net reachability analysis to ensure cyclic, bounded and undeadlocked programs. To achieve greater flexibility, we employ a dynamic, history based criterion to prune the search space. This makes our synthesis approach different from most existing code generation techniques.

Our experimental results reveal a significant reduction in algorithmic complexity (both in memory storage and CPU time) obtained for medium and large size problems.
