摘要
目前的选课系统存在着一些普遍问题,如选课不公平、实时性差、人工干预工作量大等,这些现象主要是和选课算法的好坏有直接的关系.本文对志愿分级筛选算法进行了改进,采取的改进方法是多级志愿、动态概率筛选.通过改进后的算法在选课系统中的应用和对实验数据的分析,证明了该算法是可行的,并且具有良好的公平性,实时性和选课的高命中率,达到了预期的设计目标.
There are pervasive problems in Course-selecting system such as electing course unfair,inferior real-time and big workload of manual intervention at present.These appearances relate to selecting course algorithm.In the paper,voluntary ranking screening algorithm was improved.Multilevel voluntary and screening of the dynamic probability were applied.Improved algorithm applied in selecting course system and analysis of test data proved the feasibility of the algorithm,good fairness,real-time and high percentage of selecting course were achieved.
