HYBRID SIMULATED ANNEALING AND DIRECT SEARCH METHOD FOR NONLINEAR UNCONSTRAINED GLOBAL OPTIMIZATION Abdel-Rahman Hedar and Masao Fukushima Speaker : UFO

Outline 2  Introduction  Simple direct search (SDS)  Simplex simulated annealing (SSA)  Direct search simulated annealing(DSSA)  Experimental results  conclusion

Introduction 3  This paper suggest a Simple Direct Search method  SDS is still a local search method  hybridize SDS with the standard simulated annealing called Simplex Simulated Annealing (SSA) method  Apply Nelder-Mead method on the best solutions to obtain faster convergence
