Abstract

We consider systems of cooperating logic programs which generalize dynamic deductive databases (DDDBs) from [1,2]. Some properties of the system behavior are defined which ensure an infinite steady life of the system. Decision problems for these properties of cooperating productional logic programs are investigated. It is shown that these problems are reducible to the satisfiability problem for the propositional temporal logic of branching time. It follows that stability problems for the cooperating productional logic programs are decidable with the exponential time complexity.
