We consider a network topology design problem in which an initial undirected graph underlying the network is given and the objective is to select a set of edges to add to the graph to optimize the coherence of the resulting network. We show that network coherence is a submodular function of the network topology. As a consequence, a simple greedy algorithm is guaranteed to produce near optimal edge...
We develop a procedure for computing viable (also known as controlled invariant) polytopes of a given subset of the state space under linear dynamics. The advantage of the proposed algorithm is that at every step it maintains a polytope that is itself viable. Therefore, even if the algorithm is stopped before termination it will still return a viable polytope, that can be subsequently used for controller...
We propose a method for designing randomized patrolling strategies that take into account the presence of high value areas. An importance map of the surveilled environment is constructed that explicitly accounts for (and prioritizes) high value areas. The method translates the designed importance map into pan-tilt-zoom camera specific guidance maps. Considering multiple cameras, the mapping between...
