[Scip] Branched variables

[Stefan Heinz]

Hi Ina,

yes that is possible. To do that (assuming you are using the interactive 
shell in case of the callable library its is also possible) you just 
have to specify the file in which the tree should be saved.

SCIP> set vbc filename tree.vbc

After that you read and solve your problem. This will save the search 
tree into the specified file. Using the vbctool you can visualize this tree.

Each search node knows its branching decision and dual bound. Just click 
on the a node. The color of the node gives you also some information. 
Therefore see

That is very neat feature which I use all the time.

Best Stefan
