Weight and deflection optimization of Cantilever Beam using a modified Non-Dominated sorting Genetic Algorithm

Abstract

Many problems having single or multiple objectives are routinely solved using GA methodologies. This paper is devoted to the simultaneous weight and deflection optimization of cantilever beam by using a modified Non-Dominated sorting Genetic Algorithm, subjected to maximum stress and maximum deflection constraints. The multi-objective optimization algorithm used in this paper has better sorting, incorporates elitism and no sharing parameter needs to be chosen a priori.
