Abstract

This article studies the synthesis of control policies for an agent that has to satisfy a temporal logic specification in a partially observable environment, in the presence of an adversary. The interaction of the agent (defender) with the adversary is modeled as a partially observable stochastic game. The goal is to generate a defender policy to maximize satisfaction of a given temporal logic specification under any adversary policy. The search for policies is limited to the space of finite-state controllers, which leads to a tractable approach to determine policies. We relate the satisfaction of the specification to reaching (a subset of) recurrent states of a Markov chain. We present an algorithm to determine a set of defender and adversary finite-state controllers of fixed sizes that will satisfy the temporal logic specification and prove that it is sound. We then propose a value-iteration algorithm to maximize the probability of satisfying the temporal logic specification under finite-state controllers of fixed sizes. Finally, we extend this setting to the scenario where the size of the finite-state controller of the defender can be increased to improve the satisfaction probability. We illustrate our approach with an example. [ABSTRACT FROM AUTHOR]
