Firefly algorithm with chaos

A recently developed metaheuristic optimization algorithm, firefly algorithm (FA), mimics the social behavior of fireflies based on the flashing and attraction characteristics of fireflies. In the present study, we will introduce chaos into FA so as to increase its global search mobility for robust global optimization. Detailed studies are carried out on benchmark problems with different chaotic maps. Here, 12 different chaotic maps are utilized to tune the attractive movement of the fireflies in the algorithm. The results show that some chaotic FAs can clearly outperform the standard FA.

► Novel Chaotic Improved Firefly Algorithms (CFAs) are presented for global optimization.
► Twelve different chaotic maps are utilized to improve the attraction term of the algorithm.
► Comparing the new chaotic algorithms with the standard FA demonstrates superiority of the CFAs for the benchmark functions.
