Chaotic imperialist competitive algorithm for optimum design of truss structures

The imperialist competitive algorithm is a new socio‐politically motivated optimization algorithm which recently is applied for structural problems. This paper utilizes the idea of using chaotic systems instead of random processes in the imperialist competitive algorithm. The resulting method is called chaotic imperialist competitive algorithm (CICA) in which chaotic maps are utilized to improve the movement step of the algorithm. Some well‐studied truss structures are chosen to evaluate the efficiency of the new algorithm.
