报告摘要:In this talk, we discuss the design of stochastic strategies for robotic surveillance tasks where a mobile robot moves on a graph to prevent potential intrusions. We will focus on two different approaches, i.e., an entropy maximization approach and a Stackelberg game-based approach. In the first approach, we study the novel problem of maximizing the return time entropy of a Markov chain, subject to a graph topology with travel times and stationary distribution. The return time entropy is the weighted average, over all graph nodes, of the entropy of the first return times of the Markov chain. The approach features theoretical and computational contributions. In the second approach, we consider the case where a potential intruder strategically attacks a location on the graph. The intruder is assumed to be omniscient: it knows the current location of the mobile agent and can learn the surveillance strategy. The goal for the mobile robot is to find a stochastic strategy so as to maximize the probability of capturing the intruder. We model the strategic interactions between the surveillance robot and the intruder as a Stackelberg game, and optimal and suboptimal surveillance strategies in star, complete and line graphs are studied.
