| Abstract: | In this paper, a kind of improved real coded genetic algorithm based on the judgement of searching performance is put forward. The characteristics of some real coded genetic operators are discussed, and the strategy of field division is used in the new algorithm. Numerical experiments show that the new algorithm can find the global solution of complex functions and can improve the precision of searching result greatly. The new algorithm is also used in parameter estimate, and the results of linear estimate and nonlinear estimate all show the effective of the improved algorithm. |
