本文考虑半正定矩阵锥上的一般线性规划问题。首先,我们提供了一个简单的充分条件存在的最优解和不存在的对偶差距,而不需要存在一个严格可行的解决方案。然后,我们简单地描述线性规划的标准概念的类似物,即,极值点、基、降低的成本、退化、旋转步骤以及类似单纯形的算法。
We consider the general linear programming problem over the cone of positive semi-definite matrices. We first provide a simple sufficient condition for existence of optimal solutions and absence of a duality gap without requiring existence of a strictly feasible solution. We then simply characterize the analogues of the standard concepts of linear programming, i.e., extreme points, basis, reduced cost, degeneracy, pivoting step as well as a Simplex-like algorithm.
