“…A new stochastic search algorithm and an innovative approach called Social Spider Optimization (SSO) technique has been developed in 2013 by adopting movement and mating behaviors of spider colony [12]. Despite being the new technique, the SSO algorithm has been applied on many fields such as: dispatch of thermal power unit [13], design of plug-in electric vehicle [14], wind tribune systems [15], feed forward neural networks learning [16], optical flow methods parameters [17], field weakening control of a DC motor [18] and energy theft detection systems [19]. However, any article about an application of the SSO algorithm for RW design problems has been found in the literature.…”
