Abstract: Combinatorial optimization and thermodynamics seemed to be completely unrelated fields until simulated annealing, a thermodynamic simulation procedure, proved to be so successful for combinatorial optimization problems. Some combinatorial optimization problems, like quadratic assignment problems, are extremely hard to solve by exact methods, but good suboptimal solutions are fast at hand. It will be shown that this strange asymptotic behaviour of some combinatorial optimization problems can be explained by means of the Boltzmann distribution.
