摘要
以2017年全国大学生数学建模比赛B题为基础,运用K-means算法,初步观测定价大致的分布规律,接着采用数据拟合和倒推算法分析任务未完成的原因,探讨关于“拍照赚钱”APP任务定价的相关问题.提出利用微量随机舍弃算法和定价偏差取舍原理建立定价模型,在一定程度上提高任务的完成度.
Based on Question B of the 2017 National Mathematical Contest in Modeling for college students,issues related to the task pricing of“Make Money by Photographing”APP are studied through k-means algorithm and preliminary observation of the general price distribution.Data fitting and backward inferring algorithms are used to analyze the cause of the unfinished task.Then the trace stochastic discard algorithm and the pricing deviation selection principle are proposed to establish a pricing model to improve the completion of the task.
