Abstract

A novel optimization algorithm named Ω-CMA-ES, which combines Oracle penalty function and metaheurastic, is proposed to solve a typical multi-modal and highly non-linear problem: truss sizing and shape optimization. This algorithm can alleviate the cumbersome burden of parameters setting, and thus adaptively handle the constraints of truss design. Only parameter Ω needs to be set manually while this algorithm is applied to handle various complex truss optimization problems. Numerical examples show the robustness of proposed algorithm to parameter Ω, for the algorithm can effectively handle various types of dynamic constrains; and the potential of proposed algorithm in finding global optimal solution, for the relevant performance indicators are better than the results published in the literature.
