NGA with Adaptive Crossover and Its Application in Nonlinear Circuit Analysis

A Niched Genetic Algorithm with adaptive crossover(ACNGA) is proposed.The modified algorithm can be used to solve the parameter optimization problems with multimode functions.With varying of parameter structure of solution space siutable crossover operators are adaptivly chosen and corresponding operation rates are detemined in order to maintain the diversity ofsolutions and get higher rate of convergence.ACNGA can solve nonlinear equations and nonlinear resistive circuits with arbitrary constitutive relation.
