How to Solve the Inequality Formulations?

Hi, I come from Taiwan.I have a experiment and need a algorithm to solve the inequality formulations.Does anybody know how to do it? Or Anybody can provide me some websites.Thanks. :D

Be a little more explicit. What type of solution are you looking for? Do you want a symbolic solution, or do you have a series of functions for which you need to grind out values for?

Additionally, let us know what you've thought of/tried in your attempts to solve this program.

Sorry, my post is not explicit.My variables are all integer and I want to achieve one of variables to be minimized.The formulations are like as below:
goal: minimize K
constraints:
a1 - b1 >= -X1;
a1 - b1 <= K - X2;
a2 - b2 >= -X3;
a2 - b2 <= K - X4;
.....................
.....................
{X1, X2, X3 , X4.....} are given values.{a1, a2,....}{b1,b2,...} are variables.That's my problem.
