智能组卷中遗传算法的改进研究

On the Improvement of Genetic Algorithm in Intelligent Test Paper Composition

在基本遗传算法的基础上,针对智能组卷的特点,对算法作了小生境遗传算子和操作概率的自适应调整相结合的改进。实验结果表明,改进算法具有较好的克服早熟的能力,能够满足实际组卷需求。

This paper,based on the Simple Genetic Algorithm,along with the characteristics of intelligent test paper composition,aims to improve the Simple Genetic Algorithm by introducing Niche genetic operators and self- adjusting of the probability of genetic operators.The actual tests have indicated that the intelligent test paper composition based on improved genetic algorithm can be better to overcome the premature convergence and satisfy the needs for actual examinations.
