Description
Summary:The minimum (maximum) matching problem is a fundamental problem in combinatorial optimization. The special structure of matching found by Edmonds allows to use different approximations. The idea of this work is to present a general insight of the matching problem, different sorts of algorithms for solving its original and the bi-objective formulations and a computational approach. In section 1 we describe the problem, its applications and the Grötschel-Holland algorithm (for solving using linear programming). In section 2 we introduce the theoretical background necessary for understanding the SAP algorithm and the sensitive analysis. In section 3 we implement some methods in Python 3.7 with Gurobi to study their computational properties and sensitive analysis. In section 4 we present our conclusions.
