Abstract:

Since the filled function algorithm is proposed, parameters have been regarded as the main factor restricting the efficiency of the algorithm. So it is particularly important to construct a filled function without parameters. In order to improve the efficiency and accuracy of the algorithm, a new class of parameter-free filled tunnel functions is constructed in this paper. Some properties of the new class of filled tunnel functions are analyzed. Based on the filled tunnel functions, a new global optimization algorithm is proposed, and numerical experiments are carried out on the algorithm. The numerical experiment results show that the algorithm is feasible and effective.

Key words: filled function methods, tunnel function methods, global optimization algorithm, local minimizer, global minimizer
