[Coin-discuss] Very hard MIP Models

[Mauro Scarioni]

Hi all

i've a consolidated set of MIP models running under OSL and solving well.

In particular a class of model are solved by OSL MIP presolver in very
small time.
Now i need to solve these models with Coin, but i'm not able to find
solution in reasonable time.

Has anyone got a Coin configuration that simulate the OSL MIP Presolver ?

Thank in advance

Mauro
