摘要:

针对考试系统中的试卷生成问题,提出一种基于题型的递归随机分割算法。该算法根据输入的试卷生成参数,利用概率密度函数与矩阵方程计算参数,确定各难度级别中不同题型的试题抽取数量,从而生成试卷。通过对算法的分析和生成试卷的测评,证明该算法的效率较高且通用性强,能够较好地满足考试系统需要。

Abstract:

Aiming at the test papers generating problems in examination system, a recursion random division algorithm is presented. The algorithm need input parameters for generating test papers. It uses probability density function and matrix equation to calculate parameters. It confirms the number of draw-out questions in different types and different difficulty. It uses the algorithm to generate test papers. The efficiency and adaptivity of the algorithm are demonstrated by analyzing the algorithm and evaluating the generated test papers, and the algorithm meets the requirements of examination system well.
