[Coin-discuss] How to trace Cbc?

[John J Forrest]

Spencer,

It is not finished but there is a class CbcStatistics. 

If you use branchAndBound(n) when n is 1 2 or 3 you will get increasing 
amounts of printout.  Tell me what sort of things you want.

Default is obviously 0 as it takes a lot of memory to keep entire tree.

At present it is only printed but I will add other methods if useful.

[Coin-discuss] How to trace Cbc?






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.
