摘要
针对随机抽题过程中出现的重复抽选问题,设计了一种优化的数据结构,实现了无回溯快速组卷.基于该方式,抽题前预先评估已抽取试题的分布情况,确定待抽取试题的章节范围,再从其候选集合中随机抽选试题,进而有效解决组卷过程中试题分布不合理的问题.该算法已经在试题库考试系统中得到成功应用.
Aiming at the repeated problems in the process of random extraction,an optimized data structure is designed,which can realize the rapid test paper generation without backtracking.Based on this method,the distribution of the test questions is pre evaluated in advance,so as to determine the scope of the section to be extracted.Then questions are randomly selected from the candidates,so as to effectively solve the problem of the irrational distribution in test questions.The algorithm has been successfully applied in the examination question system.
