Belief Propagation and LP Relaxation for Weighted Matching in General Graphs
Loopy belief propagation has been employed in a wide variety of applications with great empirical success, but it comes with few theoretical guarantees. In this paper we analyze t...

A decision procedure for a decidable fragment of generalized constraint diagrams
Constraint diagrams were introduced by Kent, in 1997, as an alternative to the OCL for placing formal constraints on software models. Since their introduction, constraint diagrams...

DMT optimality of LR-aided linear decoders for a general class of channels, lattice designs, and system models
The work identifies the first general, explicit, and non-random MIMO encoder-decoder structures that guarantee optimality with respect to the diversity-multiplexing tradeoff (DMT),...
