Symbolic Synthesis of Knowledge-based Program Implementations with Synchronous Semantics

Abstract

This paper deals with the automated synthesis of implementations of knowledge-based programs with respect to two synchronous semantics (clock and synchronous perfect recall). An approach to the synthesis problem based on the use of symbolic representations is described. The method has been implemented as an extension to the model checker MCK. Two applications of the implemented synthesis system are presented: the muddy children puzzle (where performance is compared to an explicit state method for a related problem implemented in the model checker DEMO), and a knowledge-based program for a dynamic leader election problem in a ring of processes.
