Survey on self-adaptive evolution software
自适应演化软件研究进展*

Through evolution technology,self-adaptive evolution may increase dynamic, flexible and changeable characteristics to software and satisfy the requirements in dynamic,opening and hard-control network environment better.Also it has been turn out well in many areas such as pervasive and embedded computing.So it is becoming one of the noteworthy focuses on the area of software technology.For further research,must summarize and conclude current achievements in self adaptive software.So the paper first summarized the characteristics of self adaptive software and proposed the main challenges.Based on these,described achievements form the level of language,architecture and framework.Then classified and compared some representative self adaptive software and gave a conceptual structure.Finally discussed the further research issues and some deficiency.
