- Abstract:
- A hybrid evaluation algorithm is proposed in this paper by combining BP neural network with genetic algorithms，in order to evaluate groundwater quality accurately and efficiently．In view of the multi—varia·ble and nonlinear characteristics of water assessment，BP neural network is introduced here to make compre—hensive evaluation and calculation．As for the shortcoming that BP algorithm is easily trapped to a local optimum，it can be overcomed through the introduction of genetic algorithms，and the two will work organically together to achieve the training and knowledge base establishment of the neural network．Through the compari—son of the algorithms and analysis of the results of the examples，the result shows this algorithm is valid．
