Abstract

We consider the problem of controller synthesis under imperfect information in a setting where there is a set of available observable predicates, each of the subset having a cost. The problem that we address is the computation of a subset of predicates sufficient for control and whose cost is minimal. Our solution avoids a full exploration of all possible subsets of predicates, uses an on-the-fly algorithm for solving the underlying games with imperfect information and reuses some information between different iterations. We apply our approach to timed systems. We have developed a prototype of tool and show the interest of our optimization algorithm on two case studies.
