Genetic Algorithm In The Test Paper In The Examination System And Research

The establishment of the item bank based on computer and realization of automatic paper-design is the important measure to make the examination more standard and scientific and a key way to separate the examination from teaching. The function of automatic paper-design is an important factor for evaluation of the system.Many Scholars make a lot of research on this problem, but there is not an appropriate method to solve this problem effectively by far. On the basis of analysis of a lot of related records, the article applies genetic algorithm to the automatic paper-design problem. According to the characteristics of the problem, the design includes individual genetic algorithm fitness function, encoding and genetic operators. The analysis has been done for the feasibility and effectiveness of the algorithm in the item bank. The results show that the algorithm can generate the approximate optimal solution in a relatively short period of time, which can meet the user's requirements, and the efficiency has increased over the previous algorithm.The main work includes:1. Establish mathematical model for automatic paper-design problem.2. Design individual genetic algorithm fitness function, encoding and genetic operators according to characteristics of the automatic paper-design problem.3. Do automatic paper-design test in the item bank.
