Real optimum method was built to calculate the weights and threshods of multi layer neural network. Through defining network average error as optimum objective function, weights and thresholds as design variable, network weights and threshods were computed quickly by terraced and conjugate terraced optimizations. Comparing terraced and conjugate terraced optimum methods with BP algorithm, validity of the methods was testified, which results in rapid computing of weights and thresholds.
