| Abstract: | How to solve the sinusoid curve-fit equation current ly is introduced in this paper, and a new method, which is based on Genetic Algori thms and Simplex Method, is proposed according to theoretical analysis of the ke y issue in the process of curve fitting. It is validated by experiment that the hybrid algorithm can find the optimized parameters of the objective function fas t and precisely. By this means, the waveform parameters of sinusoid model are ac hieved. |
