....latter. A variant of the Homer and Peinado algorithm was proposed by Burer and Monteiro [7] Their idea is based on the constrained nonlinear programming reformutation of the MAX CUT semidefinite programming relaxation obtained by a change of variables. More recently, Burer, Monteiro, and Zhang [8] proposed a rank 2 relaxation heuristic for MAX CUT and described a computer code, called circul: that produces better solutions in practice than the randomized algorithm of Goemans and Williamson. The remainder of this paper is organized as follows. In Section 2 we propose various randomized ....
....our heuristics with the randomized algo rithm of Goemans and Williamson [22] to show that the solutions produced by our randomized heuristics are of much better quality than theirs and can be found in a fraction of the time taken by their algorithm. Recently, however, Burer, Monteiro, and Zhang [8] showed that circut, a Fortran 90 implementation of their rank 2 re laxation heuristic for MAX CUT, produces higher quality approximate solutions in practice than the randomized algorithm of Goemans and Williamson. In addition, running times were shown to be small. For this reason, in this ....

....primal matrix X as LDiag(d)L T , where L is unit triangular and d # IR n . The constraint that X # 0 is replaced with the requirement that d # 0. The authors show that d is a concave function and give computational results for this reformulation. Finally we must mention that Burer et al. [8, 9] have come up with attractive heuristics for max cut and maximum stable set problems, where they solve (SDP ) with an additional restriction on the rank of the primal matrix X. AN LP APPROACH TO SDP PROBLEMS 3 The spectral bundle method requires the following assumption 1.1, which enables ....

....problems. We present an overview of this scheme in section 4. Other large scale methods include Burer et al. [10, 11, 12] who formulate (SDP ) as nonconvex programming problems using low rank factorizations of the primal matrix X, and Vanderbei et al. [43] Finally we must mention that Burer et al. [13, 14] have come up with attractive heuristics for max cut and maximum stable set problems, where they solve (SDP ) with an additional restriction on the rank of the primal matrix X. The primary objective in this paper is to develop an LP approach to solving (SDP ) The aim is to utilize some of the ....
