WebOur goal in this paper is to present a framework for the approximation of a class of integer programming problems (covering problems) through generic heuristics all based on … WebHowever, solving integer linear programs is NP-Hard. Therefore we use Linear Programming (LP) to approximate the optimal solution, OPT(I), for the integer program. First, we can relax the constraint x v2f0;1gto x v2[0;1]. It can be further simpli ed to x v 0, 8v2V. Thus, a linear programming formulation for Vertex Cover is: min X v2V w vx v ...
