Abstract

Hybrid electromagnetism-like mechanism and migration strategy(EM-MS) algorithm is a recently developed optimizationmethod which tries to benefit from both electromagnetism-likemechanism (EM) algorithm and migration strategy (MS). TheEM algorithm is a population-based meta-heuristic methodthat simulates the attraction and repulsion mechanism betweenthe charged particles to move them around the solution space.In the EM-MS method, the EM algorithm has a role of the globaloptimizer, while migration strategy (MS) helps the particles toexploit search space efficiently. In the current study, this hybridmethod is utilized for optimum design of pin jointed structuresunder stress and deflection constraints. The efficiency of theEM-MS algorithm is demonstrated through four benchmarkdesign examples. The results obtained confirm the potentialand effectiveness of the EM-MS algorithm compared to othermethods published in the recent state-of-the art literatures forthe optimum design of pin jointed structures under stress anddeflection constraints.
