SAT-Based ATL Satisfiability Checking

Synthesis of models and strategies is a very important problem in software engineering. The main element here is checking the satisfiability of formulae expressing the specification of a system to be implemented. This paper puts forward a novel method for deciding the satisfiability of formulae of Alternating-time Temporal Logic (ATL). The method presented expands on one for CTL exploit ing SAT Modulo Monotonic Theories solvers. Similarly to the CTL case, our approach appears to be very efficient. The experimental results show that we can quickly test the satisfiability of large ATL formulae that have been out of reach of the existing approaches.
