Genetic Local Search Algorithms for the Travelling Salesman Problem

We briefly review previous attempts to generate near-optimal solutions of the Traveling Salesman Problem by applying Genetic Algorithms. Following the lines of Johnson [1990] we discuss some possibilities for speeding up classical Local Search algorithms by casting them into a genetic frame. In an experimental study two such approaches, viz. Genetic Local Search with 2-Opt neighbourhoods and Li...

Parallel GPU Implementation of Iterated Local Search for the Travelling Salesman Problem

The purpose of this paper is to propose effective parallelization strategies for the Iterated Local Search (ILS) metaheuristic on Graphics Processing Units (GPU). We consider the decomposition of the 3-opt Local Search procedure on the GPU processing hardware and memory structure. Two resulting algorithms are evaluated and compared on both speedup and solution quality on a state-of-the-art Ferm...

A Gpu Implementation of Local Search Operators for Symmetric Travelling Salesman Problem

The Travelling Salesman Problem (TSP) is one of the most studied combinatorial optimization problem which is significant in many practical applications in transportation field. The TSP is an NP-hard problem and requires large computational power to be optimally solved by exact algorithms. In the past few years, fast development of generalpurpose Graphics Processing Units (GPUs) has brought huge...

Accelerating ant colony optimisation for the travelling salesman problem on the GPU

Recent Graphics Processing Units (GPUs) can be used for general purpose parallel computation. Ant Colony Optimization (ACO) approaches have been introduced as nature-inspired heuristics to find good solutions of the Traveling Salesman Problem (TSP). In ACO approaches, a number of ants traverse the cities of the TSP to find better solutions of the TSP. The ants randomly select next visiting citi...

Effective Local and Guided Variable Neighbourhood Search Methods for the Asymmetric Travelling Salesman Problem

In this paper we present effective new local and variable neighbourhood search heuristics for the asymmetric Travelling Salesman Problem. Our local search approach, HyperOpt, is inspired by a heuristic developed for a sequencing problem arising in the manufacture of printed circuit boards. In our approach we embed an exact algorithm into a local search heuristic in order to exhaustively search ...
