志愿分级筛选算法在选课系统中的分析与改进

在选课系统中,当同一门课程有多个教学班或要求学生选课必须有多个志愿时,适合使用志愿分级筛选算法。为了使选课过程更加科学化、人性化,对该算法进行了系统的分析,并从选课前准备工作、预选和正选三方面提出了改进措施,从而得到一个实用性更强,更加完善的选课算法。用改进后志愿分级筛选算法设计的选课系统,使优秀的学生可以优先选到自己感兴趣的课程,使选课系统更加人性化,更加适合学生学习的需求。

Improvement of Voluntary Screening Algorithm for Classification in Course-selecting System

In course-selecting system,the voluntary screening algorithm for classification is suitable for the situation that there is a course with several classes or a student must select more than one courses as he makes selection.The algorithm is analyzed in this paper for making the process of the course selection more scientific and humane.The improvement measures are proposed in three aspects：preparation before course selection,pre-selection and formal selection,which allow the course selection algorithm to be more perfect.The course-selecting system designed with the improved voluntary screening algorithm for classification causes the good students to have priority in course selection to their own interest,and makes the elective system more humane and more appropriate to the students.
