Stochastic Multi-Robot Monitoring on Graphs under Markovian Mobility

We study a stochastic multi-robot monitoring problem on a connected graph $G=(V,E)$, where each robot moves according to a Markov chain on $G$ and monitors the closed neighborhood of its current vertex. The performance of $r$ robots is evaluated in steady state via two objectives: average-case coverage (the expected nu...

On the Delay-Constrained Maximum Concurrent Flow Problem

A new convex relaxation expressed through second-order cone constraints is obtained from the convex envelope of a function representing the conditional delay associated with a single arc of a given path, and is shown to outperform existing formulations based on disjunctive programming.
