Topology Optimisation of A Two Point Load case Continuum Structure using Firefly Algorithm - IV

Topology optimization is a relatively new and emerging area of research in the field ofstructural engineering. The idea is to determine the optimum distribution of material in thegiven design domain and not to focus on shape or correcting the dimensions of initialdesigns. Metaheuristics are widely used in the field of optimization of continuum structures.Firefly algorithm proposed by Xin-She Yang is considered as one of the best performingalgorithms which require fewer iterations to converge. This paper is a series of ongoingresearch work in structural optimization using firefly algorithm. The focus of this paper is tooptimize a two point load case problem one of the complex in the field of optimizationinvolving several degrees of freedom. An attempt has been made to verify the distribution ofmaterial and the convergence of the firefly algorithm. The analysis shows that the algorithmis very effective to determine the distribution of material and the final distribution is a nearapproximation of the theoretical distribution
