The focus of this research was to formulate optimization model 16-bar trussesalong with stress, stability and deflection constraints. derivative free methods were used for theoptimization engineering design problems. These basically designed forunconstrained In formulated truss problems the constraints werehandled by using exterior penalty functions. results obtainedby MATLAB which demonstrated...

The success of embedded chaos in metaheuristic algorithms is mainly due to providing good balance between exploration and exploitation for metaheuristics. Comparison optimization results with standard mode shows a significant improvement quality the algorithms, thus reducing weight truss structures. Four logistic, Tenet Gaussian maps are considered improve results. Despite severely nonlinear no...
