The Dimensional Synthesis of the Four-Bar Mechanism with a Symbiotic Organisms Search Algorithm

The dimensional synthesis of the four-bar mechanism has been solved by using many meta-heuristic approaches such as genetic algorithm (GA), differential evolution (DE), and/or particle swarm optimization (PSO) However, the performance of a symbiotic organisms search (SOS) for the dimensional synthesis of the four-bar mechanism has not been investigated so far. Thus, this study aims to investigate the applicability of SOS in the optimal dimensional design of a four-bar mechanism by comparing the results gotten by SOS with those of DE, GA, and PSO. The results of SOS for the dimensional synthesis of the four-bar mechanism show that the SOS has a good exploitation ability for a fast converge rate but it has a limited exploration capability to find accurate solutions.
