The aim of this work was to investigate the possibility of using statistical mechanics as an alternative framework to study complex combinatorial optimization problems. This deep connection, suggested in ref. [1] by analogy with the annealing of a solid, allows to design a searching procedure which generates a sequence of admissible solutions. This sequence may be viewed as the random evolution of a physical system in contact with a heat-bath. As the temperature is lowered, the solutions approach the optimal solution in such a way that a well organized structure is brought out of a very large number of unpredictable outcomes. To speed up the convergence of this process, we propose a selecting procedure which favours the choice of neighbouring trial solutions. This improved version of the simulated annealing is illustrated by two examples: the N-city Travelling Salesman Problem [2] and the Minimum Perfect Euclidean Matching Problem [3].
