选课

Then thedistribution of the students during the period is analyzed and thealgorithm is proposed according to the size of the total students sample.Finally based on the research above, a modified dynamic probabilitydistribution algorithm is proposed to meet the the real-time and equitydemand of the course-selection system. Compared with the knownalgorithms, this algorithm can put in practice real-time course-selection.At the same time the anticipator can select the course with the sameprobability.

本文首先对已有的选课算法进行了比较研究，随后对选课人数随时间的分布进行了分析，并进行相关算法研究，按照选课样本的大小提出了相应的算法；最后综合上述算法，提出了一种改进的基于概率动态分布的选课算法思想，使得整个选课过程中，实时性与概率动态分布有了很好的结合与体现，既实现了实时选课，又能后使得参选人尽可能的拥有相等的机会(即实现选课过程中的相对公平合理性)选中某个课堂。

Elective system can complete a simple course, the number of control, curriculum, etc., is good.
