英文文献摘要:
A standard quadratic optimization problem (StQP) consists of nding the largest or smallest value of a (possibly indenite) quadratic form over the standard simplex which is the intersection of a hyperplane with the positive orthant. This NP-hard problem has several immediate real-world applications like the Maximum-Clique Problem, and it also occurs in a natural way as a subproblem in quadratic programming with linear constraints. We propose unconstrained reformulations of StQPs, by using dierent approaches. We test our method on clique problems from the DIMACS challenge.
一个标准二次优化问题(StQP)是由确定一个(可能是缩denite)二次型在标准单形上的最大或最小值,即超平面与正正交的交点。这个NP-hard问题有几个直接的现实应用,如最大团问题,它也以一种自然的方式出现在带有线性约束的二次规划中的子问题。我们通过使用不同的方法,提出了无约束的StQPs的重新表达式。我们用DIMACS挑战中的派系问题来测试我们的方法。
