具有实际应用前景.

Abstract

An analysis is made on the difficulty of genetic algorithms

in which the convergence is strongly dependent on the selection of initial population.A measure is proposed to alleviate the dependence of convergence on the initial population

in which two reproduction operations of different types are alternatively used in generating chromosoms.The model of improved genetic algorithm for the pattern synthesis of ultra-low side lobe linear array antenna is established.A worked out example is given to demonstrate that the independence of convergence on the selection of initial population is realized in the improved genetic algorithm

showing its good application potentials.
