对等间隔数据 ，使用快速傅里叶变换到频率域进行补零， 之后反变换回来实现数据插值的过程。程序调用了fftw库，所以在调试前请先准备fftw库。此算法目前只支持等间隔采样的数据，对于高维数据的插值可以通过，分别对每一个维度插值后最后整合起来，实现高维数据的插值。

One of the world-wide cooperative computing tasks is the "Grand Internet Mersenne Prime Search" -- GIMPS -- striving to find ever-larger prime numbers by examining a particular category of such numbers. A Mersenne number is defined as a number of the form (2p–1), where p is a prime number -- a number divisible only by one and itself. (A number that can be divided by numbers other than itself and one are called "composite" numbers, and each of these can be uniquely represented by the prime numbers that can be multiplied together to generate the composite number — referred to as its prime factors.) Initially it looks as though the Mersenne numbers are all primes. Prime Corresponding Mersenne Number 2 4–1 = 3 -- prime 3 8–1 = 7

用对分法求非线性方程f(x)=0的实根.基本思想：逐步缩小这个有根的区间，当这个区间长度减小到一定程度是，就取这个区间的中点作为根的近似值-Use of sub-method of nonlinear equation f (x) = 0 the real roots. The basic idea: to gradually narrow the range of this well-established, when the interval length decreases to a certain extent, we take the midpoint of this range as the root approximation

滤波器的设计一直是信号 iiii 重要问题处理。kCdUSe intinite 冲激响应 (IIR) 滤波器有liequency 选择和高精度的良好特性与较低的订单，它 atlracts 很多研究者的关注，是一般应用于许多领域。通讯技术、 雷达信号处理、 语音和图像信号处理。数字过滤、-IDTV。等。因为那里是没有分析方法显然当 IIR设计了数字分蘖与任何频率响应，一般采用优化方法。在本文中，NQGA 用于优化设计 01" IIR 数字分蘖频率域直接。

类是将一个未知样本分到几个预先已知类的过程。 在众多的分类模型中，应用最为广泛的两种分类模型是决策树模型(Decision Tree Model)和朴素贝叶斯模型（Naive Bayesian Model，NBC）。
