基于遗传算法的分布式数据库数据分配策略研究
Research of Data Allocation Strategy in DDB Based on Genetic Algorithm
摘要
Abstract
In order to improve further the accessing efficiency of DDBS,this paper analyzes the data allocation problem and builds a corresponding mathematical model in consideration of practical application.Based on the existing research of solving this problem with genetic algorithm,new measures are adopted to improve the genetic algorithm,for examples,an excellent original population is created by selective breeding in the initialization phase,the individuals are chosen by a rule which combines order selection and elitist selection during the evolutionary process,the big mutation is utilized to broaden the searching extent of the algorithm,and so on.Then a new data allocation strategy is put forward.The simulation results show that this strategy can be used to get a better data allocation scheme compared with other methods.关键词
