Abstract

Enhancements to two exact algorithms from the literature to solve the vertex P-center

problem are proposed. In the first approach modifications of some steps are introduced to reduce

the number of ILP iterations needed to find the optimal solution. In the second approach a simple

enhancement which uses tighter initial lower and upper bounds, and a more appropriate binary search

method are proposed to reduce the number of subproblems to be solved. These ideas are tested

on two well known sets of problems from the literature (i.e., OR-Lib and TSP-Lib problems) with

encouraging results
