Brief Information About Metaheuristic Methods

Abstract

First, the reasons of using metaheuristic algorithms are listed for optimum design of reinforced concrete (RC) structures and members. The main reason is the non-linear formulation of RC design problems including various types of design constraints. The basic terms and formulation of optimization methods are presented. A general process of metaheuristic-based optimization methods is presented. This process is summarized as three stages: pre-optimization, analysis, and optimization. Details of several metaheuristic algorithms effectively used in structural engineering problems are summarized by giving all formulations according to the inspiration of algorithms. The flowcharts for the optimization processes are also included.
