Minimum-Cost-Flow
最小费用最大流问题是经济学和管理学中的一类典型问题。在一个网络中每段路径都有“容量”和“费用”两个限制的条件下,此类问题的研究试图寻找出:流量从A到B,如何选择路径、分配经过路径的流量,可以达到所用的费用最小的要求。(Minimum cost maximum flow problem is economics and management in a class of typical problems. Each path in a network has the " capacity" and " costs" two limiting conditions, such problems of trying to find out: Flow from A to B, how to choose the path, the path of the flow through the distribution can be achieved The use of the minimum cost requirements.)

Minimum-Bayes-classifier-error-rate
这是模式识别中最小错误率Bayes分类器设计方案。
自行完善了在不同先验概率的条件下,男、女错误率和总错误率的统计,放入各个数组当中。
全部程序由主函数、最大似然估计求取概率密度子函数、最小错误率贝叶斯分类器决策子函数三块组成。
调用最大似然估计求取概率密度子函数时,第一步获取样本数据,存储为矩阵;第二步对矩阵的每一行求和,并除以样本总数N,得到平均值向量;第三步是应用公式(3-43)采用矩阵运算和循环控制语句,求得协方差矩阵;第四步通过协方差矩阵求得方差和相关系数,从而得到概率密度函数。
调用最小错误率贝叶斯分类器决策子函数时,根据先验概率数组,通过比较概率大小判断一个体重身高二维向量代表的人是男是女。
主函数第一步打开“MAIL.TXT”和“FEMALE.TXT”文件,并调用最大似然估计求取概率密度子函数,对分类器进行训练。第二步打开“test2.txt”,调用最小错误率贝叶斯分类器决策子函数,然后再将数组中逐一与已知性别的数据比较,就可以得到不同先验概率条件下错误率的统计。
