The initial states of the Hopfield models in this population are modified by a genetic algorithm and the energy functions are constructed by using a non\-negative convex combination method. Accordingly, optimization neural networks for the related optimization problem are designed. Simulation results are also presented to illustrate the effectiveness of the approach."]
