چکیده
|
The success of chaos-embedded meta-heuristic algorithms mainly results from the satisfactory tradeo between exploration and exploitation phases in meta-heuristics. comparison of optimization results with algorithms in standard mode and embedded chaos indicates the significant improvement in the quality of the meta-heuristic algorithms, thus reducing the weight of truss structures. four chaos meta-heuristic algorithms with logistic, tenet, and gaussian maps are considered to improve the results. despite truss optimization being extremely nonlinear and non-convex and often having several local optima issues, the use of di erent chaotic maps allows avoiding local optima and achieving global optimum.
