An improved fast adaptive simulated annealing algorithm

The Corana method which controls the neighborhood range is very useful since the. method automatically determines the neighborhood range,but the performance of the method in terms of the search ability is not good for multivariables optimal problems. It always falls in the local optimum. So it investigates the performance of the Corana method,, and points out the reason why couldn't finds the best optimun. Then it advances a new scheme for adjusting the neighborhood range in continuous optimization problems to obtain good solutions in shorter annealing steps. The results are tested in some examples by using simulated annealing algorithm, Corana method and improved algorithm with same parameters. The results show that this improved method has higher precision and efficiency for multivariables optimal problem than foregoing methods.
