Abstract

Metaheuristic algorithm is a powerful optimization method, in which it can solve problems by exploring the ordinarily large solution search space of these instances, that are believed to be hard in general. However, the performances of these algorithms signicantly depend on the setting of their parameter, while is not easy to set them accurately as well as completely relying on the problem's characteristic. To ne-tune the parameters automatically, many methods have been proposed to address this challenge, including fuzzy logic, chaos, random adjustment and others. All of these methods for many years have been developed independently for automatic setting of metaheuristic parameters, and integration of two or more of these methods has not yet much conducted. Thus, a method that provides advantage from combining chaos and random adjustment is proposed. Some popular metaheuristic algorithms are used to test the performance of the proposed method, i.e. simulated annealing, particle swarm optimization, dierential evolution, and harmony search. As a case study of this research is contrast enhancement for images of Cameraman, Lena, Boat and Rice. In general, the simulation results show that the proposed methods are better than the original metaheuristic, chaotic metaheuristic, and metaheuristic by random adjustment
