关于流动推销员问题的半定规划松弛

On semidefinite programming relaxations of the traveling salesman problem

Etienne de Klerk, Dmitrii V. Pasechnik, Renata Sotirov

摘要:

我们考虑一个新的半定规划(SDP)松弛的对称流动推销员问题(TSP),可以通过一个SDP松弛的更一般的二次指派问题(QAP)。我们证明了新的弛豫优于[D. Cvetkovic,M. Cangalovic和V. Kovacevic-Vujcic,对称流动推销员问题的半定规划方法,第7届国际IPCO会议,Springer,伦敦,1999年,第100页。126- 136]。与Cvetkovic等人的边界不同,新的SDP界不受Held-Karp线性规划界的支配,反之亦然。

英文摘要:

We consider a new semidefinite programming (SDP) relaxation of the symmetric traveling salesman problem (TSP) that may be obtained via an SDP relaxation of the more general quadratic assignment problem (QAP). We show that the new relaxation dominates the one in [D. Cvetkovic, M. Cangalovic, and V. Kovacevic-Vujcic, Semidefinite programming methods for the symmetric traveling salesman problem, in Proc. 7th Int. IPCO Conference, Springer, London, 1999, pp. 126--136]. Unlike the bound of Cvetkovic et al., the new SDP bound is not dominated by the Held-Karp linear programming bound, or vice versa.
