Interpolants in two-player games

We present a new application of interpolants in the context of two-player games. Two-player games is a useful formalism for the synthesis of reactive systems, with applications in device driver development, hardware design, industrial automation, etc.In particular, we consider reachability games over a finite state space, where the first player (the controller) must force the game into a given goal region given any valid behaviour of the second player (the environment). In this work, we focus on the strategy extraction problem in the context of a new counter example guided SAT-based algorithm for solving reachability games, recently proposed by Narodytska et al. We demonstrate how interpolants can be used to find a winning strategy.
