线性数学方程的方程求解器 [英] Equation Solvers for linear mathematical equations

问题描述

我需要在我的应用程序中解决几个数学方程。下面是一个典型的例子：

  a + b * c  -  d / e = a 
  
 
 
 
其他规则：
 
 
 
 
 
 10 = 0 
 
 
 b> = 0 
 
 
 b <= 100 
 
 
 
 
 
 ... 
 
 
 
 
 
我想为a，b ，c，d和e。
 
 
 
是否有任何图书馆，无论是开源或商业，求解这样的方程？如果是，他们提供什么样的结果？
解决方案
解决。可以使用线性规划来解决线性系统。我建议您查看 Boost uBLAS 为初学者 - 它有一个简单的三角解算器。然后，您可以使用指向更多特定领域方法的结帐库，也许 QSopt 。 
 
I need to solve a few mathematical equations in my application. Here's a typical example of such an equation:
a + b * c - d / e = a
Additional rules:


b % 10 = 0
b >= 0
b <= 100
Each number must be integer
...


I would like to get the possible solution sets for a, b, c, d and e.

Are there any libraries out there, either open source or commercial, which I can use to solve such an equation? If yes, what kind of result do they provide?
解决方案
Solving linear systems can generally be solved using linear programming. I'd recommend taking a look at Boost uBLAS for starters - it has a simple triangular solver. Then you might checkout libraries targeting more domain specific approaches, perhaps QSopt.
