阐述了“电路分析基础”题库系统中等概率选题数学模型的建立方法、图形信息的数字化处理及存贮方法、沿任意角α画出电路元件的算法.题库系统可同时进行汉字信息处理、图形信息处理及数值计算,达到了按实际试卷格式出题、组卷迅速、多界面人机对话的目的,既可全自动选题,又可人为选题。

Here we give a strategy for creating test papers using the Algorithm of genetics, which applies the knowledge of statistics to choosing item by probability according to the demands of test papers. And keep the chromosome of more large fitness down to next generation, this can avoid the occurrence of prematurity. At last the papers can not only satisfy the needs of creating test papers , but also refuse repetitious item in a paper.

本文提出了一个运用遗传算法来进行成卷的策略。它根据成卷要求,运用统计学的知识来进行以概率选题;并且保留了适值比较大的染色体到下一代,这样防止了早熟现象的发生。最后得出的试卷不仅能满足命题要求,还杜绝了在一张试卷中出现重题。
