Analysis and improvement on roulette wheel method of genetic algorithm

Roulette wheel method is the base of Genetic Algorithm(GA),and it is firmly related to the operations of reproduction and crossover.This paper researches into the optimization for roulette wheel method from the view of pure Genetic Algorithm,and analyzes the large numbers of actual computing results by the tools of database and statistic.The analysis indicates that it can obviously improve the successful probability of obtaining global optimization result as well as the computing efficiency while using the improved roulette wheel method in Genetic Algorithm.
