A Kind Of Course-Choosing Algorithm Based On The Dynamic Probability Distribution And Its Application

With the fast development and generally using of the internet, the students are widely demanded to select the course independently after the credit system is put in practice in the colleges in china. The course-selection system is transferred form manned filling table to selecting the courses in the web. Based on the methods used in other course-selection systems, one kind of course-selection algorithm on the base of dynamic probability distribution, which can be more open, more equitable, more rational for most of the students, is proposed.This algorithm starts from the equity for the students to select the courses. It can make most of the students can choose some courses with almost the same probability, and can make all the students can know if they pitched on the course in the time as short as possible. Firstly the algorithms proposed by others are compared and studied. Then the distribution of the students during the period is analyzed and the algorithm is proposed according to the size of the total students sample. Finally based on the research above, a modified dynamic probability distribution algorithm is proposed to meet the the real-time and equity demand of the course-selection system. Compared with the known algorithms, this algorithm can put in practice real-time course-selection. At the same time the anticipator can select the course with the same probability.
