Research and Development of Algorithmic Program Transformation

Due to the creative work involved, the development of algorithmic programs is still one of the most challeng- ing problems in computer field. In order to improve algorithmic programs' reliability and productivity, people are turn- ing to the automation of its development. Algorithmic program transformation, is an efficient approach to realize algo- rithmic programs development automation, has been an important research topic in software automation field, and now on which many researches have made progress. The basic concepts about algorithmic program transformation are intro- duced, and then its classification is presented. Several typical algorithmic program transformation projects are com- pared and analyzed in many aspects, such as methodology, language, the capability of algorithm design, the supported tool and its application, etc. The existing problems of current works and future research direction are discussed.
