Afandi, A.N. Pendahuluan. 2013. Recent years evolutionary methods are frequent used to solve optimization problems. A novel method of this group is Artificial Bee Colony (ABC) algorithm imitated foraging behavior of honeybees in nature [1]. Presently, the important challenges of the ABC are devoted to convergence speed, searching mechanism and real applications [2], [5]. As part of works to improve the ABC becomes Harvest Season Artificial Bee Colony (HSABC), this paper introduces multiple food sources for composing the HSABC applied to economic dispatch problem.
