Selection of Relaxation Problems for a Class of Asymmetric Traveling Salesman Problem Instances

It is commonly believed that the use of the assignment problem works well when one selects a relaxation problem within the framework of a branch and bound algorithm to solve an asymmetric traveling salesman problem (TS P) optimally. In this paper, we present asymmetric TSP instances found in real-life setting, and show that t.he above common belief is not necessarily appropriate. Based on the r...

An Approach for Solving Traveling Salesman Problem

In this paper, we introduce a new approach for solving the traveling salesman problems (TSP) and provide a solution algorithm for a variant of this problem. The concept of the proposed method is based on the Hungarian algorithm, which has been used to solve an assignment problem for reaching an optimal solution. We introduced a new fittest criterion for crossing over such problems, and illu...

When is the Assignment Bound Tight for the Asymmetric Traveling Salesman Problem?

We consider the probabilistic relationship between the value of a random asymmetric traveling salesman problem ATSP (M) and the value of its assignment relaxation AP (M). We assume here that the costs are given by an n × n matrix M whose entries are independently and identically distributed. We focus on the relationship between Pr(ATSP (M) = AP (M)) and the probability pn that any particular en...

Solving Traveling Salesman Problem based on Biogeography-based Optimization and Edge Assembly Cross-over

Biogeography-Based Optimization (BBO) algorithm has recently been of great interest to researchers for simplicity of implementation, efficiency, and the low number of parameters. The BBO Algorithm in optimization problems is one of the new algorithms which have been developed based on the biogeography concept. This algorithm uses the idea of animal migration to find suitable habitats for solvin...
