This paper analyses characters of BP algorithm、 GA algorithm and GA-BP-APARTING algorithm.GA-BP-NESTING algorithm is proposed in this paper.Under the mode of on-line learning,off-line learning of neural network,using three algorithms to train the network respectively: Backpropagation(BP) algorithm、Genetic Algorithm(GA)、GA-BP-APARTING algorithm and GA-BP-NESTING algorithm.In the end of the paper,simulating a case under the two modes does a comparative study of the three algorithms.We can obtain the conclusion that initializing weights of networks is vital of training ANN and the GA-BP-NESTING algorithm under the mode of off-line learning is the best.
