Fuzzy Approach for Optimization of Cold-Formed Cross Sections

This paper presents a fuzzy procedure for obtaining optimal design of channel section shapes under bending moment. The proposed approach refers to an ideal, equivalent single objective representation for the bicriteria objectives, where the cross-sectional area of thin-walled beam is the first objective, while the deflection of the beam is the second one. The design variables were selected as t...

SWITCHING TEAMS ALGORITHM FOR SIZING OPTIMIZATION OF TRUSS STRUCTURES

Meta-heuristics have received increasing attention in recent years. The present article introduces a novel method in such a class that distinguishes a number of artificial search agents called players within two teams. At each iteration, the active player concerns some other players in both teams to construct its special movements and to get more score. At the end of some iterations (like quart...

Truss Optimization Using Genetic Algorithms

This paper reports research on the design of structures using genetic algorithms. It presents the design of a program that uses genetic algorithms to optimize a truss structure, along with an example of truss optimization.

A FAST GA-BASED METHOD FOR SOLVING TRUSS OPTIMIZATION PROBLEMS

Due to the complex structural issues and increasing number of design variables, a rather fast optimization algorithm to lead to a global swift convergence history without multiple attempts may be of major concern. Genetic Algorithm (GA) includes random numerical technique that is inspired by nature and is used to solve optimization problems. In this study, a novel GA method based on self-a...
