en Optimal design Optimal design پژوهشي Research <p>In this paper, MATLAB code for a recently developed meta-heuristic methodology, the vibrating particles system (VPS) algorithm, is presented. The VPS is a population-based algorithm which simulates a free vibration of single degree of freedom systems with viscous damping. The particles gradually approach to their equilibrium positions that are achieved from current population and historically best position. Two truss towers with 942 and 2386 elements are examined for the validity of the present algorithm; however, the performance VPS has already been proven through truss and frame design optimization problems.</p> <p></p> vibrating particles system algorithm, MATLAB, meta-heuristic, structural optimization. 355 366 http://ijoce.iust.ac.ir/browse.php?a_code=A-10-66-144&slc_lang=en&sid=1 A.
