Magnetic charged system search for structural optimization

Abstract

In this paper the Magnetic Charged System Search algorithm is applied to structural optimization. This algorithm uses the Biot-Savar law of electromagnetism to incorporate magnetic forces into the already existing Charged System Search algorithm and thus can be considered as an extension of it. Each search agent exerts magnetic forces on other agents based on the variation of its objective function value during its last movement. This additional force provides some additional information and enhances the performance of the Charged System Search. The efficiency of the Magnetic Charged System Search is examined by application of this algorithm to four structural optimization problems. The results are compared to those of CSS and some of the methods available in the literature.
