Nettet1. mai 1980 · The complexity of linear programming and other problems in the geometry of d -dimensions is studied. A notion of LP-completeness is introduced, and a set of … NettetDefine a linear program as follows: Given that the constraints limit to either 0 or 1, any feasible solution to the integer program is a subset of vertices. The first constraint implies that at least one end point of every edge is included in this subset. Therefore, the solution describes a vertex cover.
