RESUMO
In this work a fixed cost essentially local optimization method, which becomes global if the number of evaluations increases is developed. Globalization is achieved by probabilistic restarts based on past searches. An improved Nelder-Mead method is the local optimizer. Improvements concern the variables which are bounded, the nonlinear inequality constraints which are taken into account by adaptive penalization, and the failures by simplex degeneration which are detected and handled through restart. The resulting method is called Globalized and Bounded Nelder-Mead (GBNM). Numerical experiments on multimodal test functions and composite laminated design problems illustrate the performance of the method as compared to an evolutionary optimizer. More complex applications are dealt with GBNM : the flexural stiffness optimization and the identification of the ply drop positions of swimming monofins.
