Abstract

In the game theoretic approach to the synthesis of reactive systems, specifications are often given in linear time logic (LTL). Computing a winning strategy to an infinite game whose winning condition is the set of LTL properties is the main step in obtaining an implementation. We present a practical hybrid algorithm--a combination of symbolic and explicit algorithm--for the computation of winning strategies for unrestricted LTL games that we have successfully applied to synthesize reactive systems with up to 1011 states.
