组卷难度分布算法的研究

Study of difficulty distribution algorithm in intelligent grouping test paper

创建了离散型随机分布函数Poisson分布构建程序算法,来完成计算机智能组卷系统中试题的难度分布问题,并结合循环约束抽题算法,快速准确的从试题库中抽取符合出题者要求的试卷,此算法不仅保证了组卷的成功率,而且提高了数据运算的时间效率。

A kind of programme algorithm is constructed using discrete sequence of random variable distribution function Poisson,which can achieve the difficulty distribution of test questions in the wit selecting test paper programme , and the circle constraint is used in this algorithm. The test questions which accord with the needs of teachers can be selected quickly from test questions storeroom. This grouping algorithm improved not only the success ratio of grouping test paper, but also the time efficiency of date operation.
