Cutting Planes Gruppe 2

Idea

The Idea of the Cutting Plane is to add Restrictions (the Cutting Planes) to contract the solution space more and more to get integers. These restrictions cut of the non-integer parts of the solution.


Approach

First of all you should divide your restrictions trough the greates common factor.

Example: 6x1 – 15x2 <= 120
