Hi every one,
I have developed an algorithm for solving linear integer programming, and I need a set of medium and large size samples to test my algorithm. It would be appreciated, if you let me any database in this regard.
Dear All
I found the related database, If you are looking for integer programming model samples you can refer to following cite:
