The solution to it has experienced from global justification to local justification and to new global justification.

To overcome these deficiencies resulting in the precocity and stagnation,the parameters of the city selective strategy and the local optimization searching strategy are adopted.

The improvements of NGA are as following:the discriminating standard L for distances among individuals set as dynamic function to keep the diversity of colonies;the elitist strategy is adopted to ensure the convergence of the algorithm;the circling strategy of local extreme values is used as auxiliary termination principle to avoid falling into local optima.
