Semidefinite Programming Relaxations for the Graph Partitioning Problem
A semideenite programming, SDP, relaxation for the graph partitioning problem, GP, is derived using the dual of the (homogenized) Lagrangian dual of appropriate equivalent representations of GP. The special structure of the relaxation is exploited in order to project the SDP onto the minimal face, of the cone of positive semideenite matrices, which contains the feasible set. This guarantees tha...
متن کاملSemide nite programming relaxations for the graph partitioning problem (
A new semide nite programming, SDP, relaxation for the general graph partitioning problem, GP, is derived. The relaxation arises from the dual of the (homogenized) Lagrangian dual of an appropriate quadratic representation of GP. The quadratic representation includes a representation of the 0,1 constraints in GP. The special structure of the relaxation is exploited in order to project onto the ...
متن کاملSemidefinite Programming Relaxations for the Quadratic Assignment Problem
Semideenite programming (SDP) relaxations for the quadratic assignment problem (QAP) are derived using the dual of the (homogenized) Lagrangian dual of appropriate equivalent representations of QAP. These relaxations result in the interesting, special, case where only the dual problem of the SDP relaxation has strict interior, i.e. the Slater constraint qualii-cation always fails for the primal...
متن کاملStrengthened Semidefinite Programming Relaxations for the Max-cut Problem
In this paper we summarize recent results on finding tight semidefinite programming relaxations for the Max-Cut problem and hence tight upper bounds on its optimal value. Our results hold for every instance of Max-Cut and in particular we make no assumptions on the edge weights. We present two strengthenings of the well-known semidefinite programming relaxation of Max-Cut studied by Goemans and...
متن کاملOn semidefinite programming relaxations for the satisfiability problem
This paper is concerned with the analysis and comparison of semidefinite programming (SDP) relaxations for the satisfiability (SAT) problem. Our presentation is focussed on the special case of 3-SAT, but the ideas presented can in principle be extended to any instance of SAT specified by a set of boolean variables and a propositional formula in conjunctive normal form. We propose a new SDP rela...
