3、thm is Very’popular in recent years，it is widelyused in complex optimization questions because of it’s easy imp lementation and has lesscontrol parameters ． But conventional differential evolution algorithm has a problem

4、 ofstagnation that can stop the algorithm convergence．Aiming to solve the problem anotherending condition was proposed，also can change the number of population(N)，variationcoeficient(F)and crossover coeficient (CR)in com

5、puting process．Elite tactic was added tothe computing process to quicken the convergence speed and make diff-erentialevolution algorithm converge to best solutions．Via computing typical testing function,theresults comput

6、ed by modified differential evolution algorithm are more excellent thanconventional differential evolution algorithm and also converge more faster，so it provedthe DE is very usefu1．Key words：differential evolution algori
