,Monoidal Strengthening and Unique Lifting in MIQCPs,for quadratically-constrained optimization problems by exploiting integrality requirements. We provide an explicit construction that allows an efficient implementation of the strengthened cuts along with computational results showing their improvements over the standard intersection cuts. We also shNIL 发表于 2025-3-27 01:35:58

,On the Correlation Gap of Matroids,has been identified as the performance guarantee in a range of approximation algorithms and mechanism design settings. It is known that the correlation gap of a monotone submodular function is at least ., and this is tight for simple matroid rank functions..

,A 4/3-Approximation Algorithm for Half-Integral Cycle Cut Instances of the TSP,he TSP (sometimes called the Subtour LP or the Held-Karp bound) is at most 4/3 for symmetric instances of the TSP obeying the triangle inequality. In this paper we consider the half-integral case, in which a feasible solution to the LP has solution values in .. Karlin, Klein, and Oveis Gharan [.], i
