【Abstract】 The new organism called Genetic BP based neural net is established, which integrates Genetic algorithm with BP neural net. To compare the performance of the Genetic BP based neural net with the traditional BP neural net, a test is carried out. It is shown that the performance of the Genetic BP based neural net in speed of convergence and stability of convergence is very good. An application of Genetic BP based neural net to solve the mechanical parameters of ZWT nonlinear viscoelastic equation of high polymer is conducted.更多还原
