An Improved Imperialist Competitive Algorithm Based on a New Assimilation Strategy

Meta-heuristic algorithms inspired by the natural processes are part of the optimization algorithms that they have been considered in recent years, such as genetic algorithm, particle swarm optimization, ant colony optimization, firefly algorithm. recently, a new kind of evolutionary algorithm has been proposed that it is inspired by the human evolution process. this new algorithm has been called imperialist competitive algorithm (ica). the ica is a population-based algorithm where the population is represented by countries that are classified as colonies or imperialists. this paper is going to present a modified ica with high accuracy, referred to here as ica2. the ica2 is tested with six well-known benchmark functions. results show high accuracy and avoidance of local optimum traps to reach the minimum global optimal. two main operators of the ica are assimilation and revolution. assimilation policy is the more important than revolution. this research focuses on an assimilation policy in the ica to propose a meta-heuristic optimization algorithm for optimizing function with high accuracy and avoiding to trap in local optima rather than using original ica.
