[Coin-discuss] How to trace Cbc?

[Spencer Fung]

Hi,

 

Does anyone know how to trace the branch-and-bound search with Cbc?
Actually, I want to know the following information at each variable branch:

 

1.       The solution of the LP relaxation

2.       The variable is being branched

3.       The direction of the branch (left or right?)

 

Also, what is the default branching heuristic for Cbc?

 

Thanks.

 

Spencer
