[Coin-discuss] Counting the number of branches

[John J Forrest]

Spencer,

I am not sure what you mean by backtracks as Cbc does not really do a 
depth first search.  Cbc does not give the statistics you want but you can 
get much of the information you want.  If you uncomment the #define 
PRINTIT at line 2657 of CbcNode.cpp you will get all the useful 
information I can think of which you could then summarise in some way. 

I modified the code so that the parent node was easily obtainable.

As a general point do people want more statistics and if so what sort?

[Coin-discuss] Counting the number of branches






Dear All,
 
I am using the CBC MIP solver thru the OsiCbc interface to solve a large 
0-1 Integer Problem. I want to know is there any function to retrieve the 
number of (left/right) branches, and number of backtracks?
 
Thanks.
 
Regard,
Spencer_______________________________________________
