This paper describes a fast heuristic algorithm based on branch-and-bound for the traveling salesman problem with a set approximation ratio, i.e. with a parameter k that guarantees that the solution obtained by the algorithm is at most 1/k times worse than the optimal solution. The algorithm is designed for shared-memory systems.
Keywords: traveling salesman problem, exact algorithm, parallel algorithm, branch-and-bound.
Mots-clés : heuristic algorithm
