CHAOTIC VARIANTS OF THE PSO-SRM FOR OPTIMUM DESIGN OF THE STEEL FRAMES

This paper presents the chaotic variants of the particle swarm optimization-statistical regeneration mechanism (PSO-SRM). The nine chaotic maps named Chebyshev, Circle, Iterative, Logistic, Piecewise, Sine, Singer, Sinusoidal, and Tent are used to increase the performance of the PSO-SRM. These maps are utilized instead of the random number, which defines the solution generation method. The robustness and performance of these methods are tested in the three steel frame design problems, including the ۱-bay ۱۰-story steel frame, ۳-bay ۱۵-story steel frame, and ۳-bay ۲۴-story steel frame. The optimization results reveal that the applied chaotic maps improve the performance of the PSO-SRM.
