Figure (IMAGE) Kanazawa University Caption Schematic diagram of SFABC. The scale-free artificial bee colony algorithm (SFABC) in which the search is guided by a scale-free network is proposed. The mechanism enables the SFABC search to follow two rules. First, the bad food sources can learn more information from the good sources of their neighbors. Second, the information exchange among good food sources is relatively rare. The employed bees are ranked based on the qualities of their food sources and labeled by the ranking values.
