最优化问题本质是一个求极值问题，几乎所有类型的优化问题都可概括为如下模型：给定一个集合（可行集）和该集合上的一个函数（目标函数），要计算此函数在集合上的极值。-Optimization problem is an extremum nature of the problem, almost all types of optimization models can be summarized as follows: given a set of (feasible set) and a funct

经典最优化方法最优化方法是一门古老而又年青的学科。这门学科的源头可以追溯到17世纪法国数学家拉格朗日关于一个函数在一组等式约束条件下的极值问题（求解多元函数极值的Lagrange乘数法）。-Classical optimization methods optimization method is an old and young subjects. The source of this discipline can be traced back to 17th century French ma

K-means算法是硬聚类算法，是典型的基于原型的目标函数聚类方法的代表，它是数据点到原型的某种距离作为优化的目标函数，利用函数求极值的方法得到迭代运算的调整规则。-K-means clustering algorithm is hard, is a typical prototype-based clustering method on behalf of the objective function, it is a method of data points to a certain di
