Abstract

Inference and optimisation of real-value edge variables in sparse graphs are studied using the tree based Bethe approximation optimisation algorithms. Equilibrium states of general energy functions involving a large set of real edgevariables that interact at the network nodes are obtained for networks in various cases. These include different cost functions, connectivity values, constraints on the edge bandwidth and the case of multiclass optimisation

Keywords: Approximation algorithms Bandwidth Communication system control Computer networks Cost function Distributed computing Message passing Physics Resource management Routing
