基于随机抽题策略的算法改进

Improved Analysis Based on Random Selection Algorithm

组卷策略是考试系统的重点和难点,合理设置试题库和组卷参数是组卷策略的关键.本文基于传统随机抽题算法提出了“数据结构+分类分段随机抽取”的方法,能够使题库系统更符合教师的习惯和实际需求,组卷更灵活.

The strategy of test paper formation is the key and difficult point in the examination system.The key to the strategy is to set the test question bank and the test paper parameters reasonably.Based on the traditional random question extraction algorithm,this paper proposes a method of"data structure+classification segmentation random extraction",which can make the question bank system more in line with teachers5 habits and actual needs,and make the test paper more flexible.
