适合数据，其中包含异常值使用许多不同的方法对椭圆大多数都基于：1 / 5 点多做适合2 选择最好的一个3 / 标记相4/抛光 (即改装到使用标准的最小二乘代数距离准则相)".

背景：在需求工程中，将有许多不同的股权持有人。经常要求

大数类，重载了各类操作符，可以完成大数计算功能-big number function

大致想法就是对于一个数abcdefg。。。比他小或等于的有abcdefg 个，其中不包括9的有（大致就是转成9进制， 如果不存在9的话转出来的大小就是小于等于abcdefg有几个十进制的数）a*9^n + b * 9 ^(n-1)....这样。但对于在高位出现过9了，那么低位的数字也就没有意义了，计算的话反而会重复，就在高位的下一位不+就好了 所以比abcdefg小的9的个数就是abcdefg-a*9^n + b * 9 ^(n-1)。。。这样多个。 一个高精度*纯洁的数字 + 高精度的加减操作就好了（因为确认了b >= a）。。 很奇怪大神们的思想都是一开始打表10^n - 9 ^ n什么的这样。。 渣渣的思路一开始就是一级一级往上乘果然跟大神们不是一个思维方式

应用背景下面是我对纪律的随机搜索方法实现：优化方法关键技术无约束优化

本实验主要涉及解线性方程组的列主元消去法.通过编辑程序,能更深入地了解到列主元消去法的内涵.并且通过计算比较,也可以了解到数据的精度及舍入误差等一系列有关因素.-this study involved solving linear equations of main-element elimination. Through the editorial process, to better understand out to the main yuan elimination connotations. through calculation and comparison, Data can also understand that the accuracy of rounding error and a series of other relevant factors.

C4.5的简化版本是一个决策树的算法-C4.5 is a simplified version of the Decision Tree Algorithm

一个有关进制的和程序，它将一定范围内的数编制成组，通过从二进位制到十进位制， 进行编组，输入进制数和组数，即可自动计算出数据，并显示在屏幕上，同时输出到文件中，是很不错的程序，我用了好几天才编好，很精悍！-one of the 229 and procedures, it would certainly within the scope of the report into several groups, By binary system to the decimal system, organization, and the importation of 229 for a group, they will automatically calculate data, displayed on the screen, while the output to a file, is a very good procedure, I spent several days prepared and very lean!

平均因子分解法，适用于正定矩阵First, let s recall the definition of the Cholesky decomposition: Given a symmetric positive definite square matrix X, the Cholesky decomposition of X is the factorization X=U U, where U is the square root matrix of X, and satisfies: (1) U U = X (2) U is upper triangular (that is, it has all zeros below the diagonal). It seems that the assumption of positive definiteness is necessary. Actually, it is "positive definite" which guarantees the existence of such kind of decomposition. -Average factor decomposition method applied to positive definite matrix First, let s recall the definition of the Cholesky decomposition: Given a symmetric positive definite square matrix X, the Cholesky decomposition of X is the factorization X = UU, where U is the square root matrix of X, and satisfies: (1) UU = X (2) U is upper triangular (that is, it has all zeros below the diagonal).
