Vibrating Particles System (VPS) is developed based on some principles of physics in which the free vibration of a system with single degree of freedom including viscous damping is concerned. In this algorithm, each possible solution or vibrating particle seeks its equilibrium position in the search space. Despite of a relatively good exploration ability of the VPS algorithm, it is poor at exploitation and the convergence speed of this algorithm is also an issue in some cases. In this paper, the VPS algorithm is hybridized with the Migration-Based Local Search (MBLS) mechanism of the Biogeography-Based Optimization (BBO) algorithm with the strong local search capability to concentrate the search process around promising vibrating particles and locate the optimum solution more precisely. Three hybrid algorithms are developed based on how to use the VPS and MBLS methods as parallel, series and mixed series–parallel schemes. In order to evaluate the capability of the proposed hybrid methods in dealing with difficult structural optimization problems, a 24-story benchmark frame problem, a 10-story steel structure with 1026 structural members alongside a 20-story steel structure with 3860 members are optimized using presented algorithms. The findings affirm the robustness and efficiency of the proposed hybrid methods over the standard existing relevant approaches for optimum design of steel building structures.
