摘要
针对计算机辅助测试中试卷生成问题的约束指标,详细设计了试题的数据结构,在解决试卷难度、曝光度和章分数约束的基础上,建立了组卷问题的多目标约束数学模型.以此数学模型作为适应度评价函数,利用遗传算法进行组卷.在组卷过程中,完成了编码方案和遗传算子的优化设计.
In view of constraint index of paper generation problem in computer aided test,this paper designs the test data structure of examination questions detailed.On the basis of solving difficulty of exam paper,constraint of exposure and chapter fraction,the paper establishes the test paper problem multi objective constrained mathematical model.Using this mathematical model as the fitness function,genetic algorithm is used to generate examination paper.In the process of examination paper generating,the coding scheme and genetic operators optimization design is completed.
