出差旅行推销员的问题，解决问题使用人工智能此代码

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

一个vb程序，用坐标系来演示各种圆锥曲线,非常直观.-a procedure used to coordinate the various demonstration conic and very intuitive.

应用背景This application is to focus on the numerical methods in Computational Fluid Mechanics, dealing with aeronautics, hydraulics, heat and mass transfer etc. We konw fluids have the ability to transport matter and its propertities as well as transmit force, therefore fluid mechanics is a subject that is particularly open to cross fertilization with other sciences and disciplines of engineering. The subject of fluid mechanics will be highly relevant in domains such as chemical,metallurgical, biological and ecological engineering.关键技术 SIMPLE (Semi-Implicit Method for Pressure Linked Equations) algrithm is the principal numerical method to numerical simulate incompressible fluid flow, it can remove the difficults of fake pressure disturbance and neglecting specific pressure equation for incompressible fluid flow successful. The main thoughts and steps of SIMPLE algorithm are given in this application. The single-phase loc
