An Agent-based Logic Description Language for Dynamic Evolution

Application of Agent technology to software evolution is considered to be a possible approach to make software be adaptable to environment change. The dynamic characteristic of environment causes difficulty to predict and control the act of Agent in software. Well-defined evolution logic is helpful to describe and limit individual behavior of Agent and coordination among Agents. In this paper, in view to dynamic environment, a process of software evolution in this kind of environment is given. In this process, Agent-based Software Evolution Logic Description Language (Agent SELDL) presented in this paper can give a particular description of evolution process and its logic. Finally, the validity of Agent SELDL is proved by an experiment of software evolution process in dynamic environment.

I. Introduction

Compared with the early software, in the amount of code and data are handled of current software are higher than several orders of magnitude. This prompts the software must contain a large number of independent and autonomous unit through interaction and computing resources can join or leave the system dynamically. Software in its life cycle should meet changing needs based on the constantly environment evolving [1]. As a basic unit of computing and programming abstraction, Agent can support the realization of target software system, while describe and modeling software system as high-level abstraction [2] [3] and Agents in the system should have self-organizing, adaptive capacity to adapt to the environment and requirements [4]. How to define the logic of software evolution which can consistent with the requirements of the dynamic evolution and application logic is important.
