Three derivative free methods, namely Nelder-Meed method, Hooke-Jeeve Method and Multidirectional search Methods are used. In this model penalty functions are utilized to remove constraints. In thusly the constrained optimization model is changed into unconstrained model. MATLAB is being used to get results which show the efficiency and success of these methods.enMathematicsDerivative free methods, Penalty function, Structural optimization problem, Unconstrained optimization.Article
