<para> In this paper, we investigate the use of message- passing algorithms for the problem of finding the max-weight independent set (MWIS) in a graph. First, we study the performance of the classical loopy max-product belief propagation. We show that each fixed-point estimate of max product can be mapped in a natural way to an extreme point of the linear programming (LP) polytope associated...
Consider the well-studied decentralized Bayesian detection problem with the twist of an undirected network topology, each edge representing a bidirectional (and perhaps unreliable) finite-rate communication link between two distributed sensor nodes. Every node operates in parallel, processing any particular local measurement in two (discrete) decision stages: the first selects the symbols (if any)...
