摘要
计算机考试系统广泛地应用于各种考试,其中抽题算法的优劣在某种程度上决定了考试系统的性能.本文运用数据结构中的"哈希函数"为模型表述了回溯抽题算法,分析了试题库的知识点模型和试题的冲突处理,对考试系统的设计有一定的理论指导意义.
The computer exam system is widely applied in a great variety of exams, and in some degree the arithmetic for selecting examination questions determines the performance of the exam system. This paper relates the tracing and arithmetic for selecting examination questions with the model of the Hash function of data structure, and analyses the knowledge point model of the test storeroom and the conflict disposal of test. It has some instructional meanings in the design of the exam system in theory.
