摘 要: 计算机辅助教学 CAI(Com puter Assisted Instruction)的一个重要应用是计算机辅助测验 CBT(Com puter-Based Testing) .智能组卷是 CBT的基础 ,组卷中关键是解决约束优化问题 .在研究现代教育测试理论与计算机辅助测验 CBT的基础上 ,提出一种解决计算机组卷中约束优化问题的方法自适应遗传算法 .该方法有效地解决了基于IRT的智能组卷问题 ,为解决约束优化问题提供一种新的有效途径 ,具有较好的性能和实用性 . One of the important applications on Computer Assisted Instruction (CAI) is Computer-based Testing. Computer Test Construction is the basis of CBT, which key problem is to solve constraint optimization problems. On the research of modern test theory and CBT, an adaptive genetic algorithm is given here to solve the problems of computer test construction based on IRT. The results indicated that AGA could solve the problems effectively, which gives us a new way to solve constraint optimization problems with good performance and practicability.
