In this paper an improved Hopfield neural network algorithm was given, the applicable conditions of Hopfield neural network models of memory storage is greater than the storage capacity of the perfect search. To overcome the following limitations of Hopfield neural network algorithm: It is not the ideal storage capacity problem, it lack of inter-related, the Pattern of memory and sometimes cannot be too close to the Hopfield neural network algorithm recal1 a stored memory pattern mode1 is not any one model, but it drop into a “pse...
