Application Of Automatic Composing Test Paper Based On The Genetic Algorithm

As the development of computer technique and Network technology, the intelligent exam paper generating system is more and more paid attention to by a lot of scientists. The establishment of the item bank based on computer and realization of automatic paper-design is the important measure to make the examination more scientific and a key way to separate the examination from teaching. The development of the intelligent exam paper generating system not only saves a lot of time, but also makes the examination more standardization.The author analyzes a great deal of articles, based on Genetic Algorithm, analyzing the papers of indicators and the role of several important indicators of the relationship between them. According to the knowledge based on the use of indicators constructed distribution model definition into the evaluation of the quality of the papers and finally, a mathematic modal to generate exam paper was established. At the same time, use the properties of Genetic Algorithm of full-selecting-excellent and intelligence searching, so a satisfying exam papers from exam storeroom is obtained.The exam paper generating system not only comes down to the establishment of mathematics model, but also relates to the applied algorithm. While leading the Genetic Algorithm into auto generating exam paper, several researches must be solved: the Code problem, the design of fitness, genetic operators and control parameters, etc. The test results showed that the improved algorithm could evidently improve success ratio convergence speed and solve the problem of intelligent generating exam paper more effectively.In use of ASP.NET Dynamic website technology and SQL Server 2000 database, this paper Designed and realized of the intelligent exam paper generating system based on Genetic Algorithm, and conducted a lot of experiments. The result of the experiments shows that the system is reasonable and effective.
