GMP是计算任意精度的数学库, 包括支持整数,有理数和浮点. GMP包括大量的接口函数.-GMP is a free library for arbitrary precision arithmetic, operating on signed integers, rational numbers, and floating point numbers. There is no practical limit to the precision except the ones implied by the available memory in the machine GMP runs on. GMP has a rich set of functions, and the functions have a regular interface.

EM算法，基于期望最大化原则进行密度估计-EM algorithm, based on the expectation maximization of the principle of density estimation

The CVRP is a hard combinatorial optimisation problem. The scenario is that a set of depots contains goods to be delivered to customers by a fleet of trucks. Each customer wants a certain integer amount of goods called their demand and each truck can only carry a certain amount called its capacity. All trucks have the same capacity. The objective is to find a set of routes, one for each truck, which minimises the total distance travelled by all trucks (the  请点击左侧文件开始预览 ！预览只提供20%的代码片段，完整代码需下载后查看 加载中 侵权举报

xfoi是一个为设计和分析亚音速飞机独立翼型编写的互动式的程序。它由下列执行各种函数的一系列菜单操作程序组成：-对一种已经存在的的翼型的粘流（或无粘流）分析，允许：*强制或自由转换*转捩的气泡分离*除了最大升力系数还可以对升力和阻力预测*卡门- 钱学森压缩性修正-通过屏幕指针或鼠标操作指定特定的表面速度分布，对翼型进行设计和优化设计。两种这样的工具可以实现：*完全反设计：基于一个复杂的绘图公式；*混合反设计: 一种xfoil的基本嵌版方法（面涡法）的扩展完全反设计允许多点设计，而混合反设计则需要对翼型个部分相对严格的几何约束
