[SCIP] NodeSelector hirachy

Dear SCIP-collective mind, 

 

I would like to implement a NodeSelector which calls nodes again that have
previously been branched by early branching, but which would now potentially
lead to bounds due to a newly found Primalbound in a different leaf. 

My starting point was, similar to the branching rules, to build a new
NodeSelector that checks whether it finds a suitable node and if not, to use
the next-best NodeSelector from SCIP.

Now with "SCIP_DECL_NODESELSELECT" I see no possibility to say that no
interesting node has been found by this selector, but there might still be
one.

 

Perhaps one of you has already dealt with a similar problem with
hierarchical NodeSelectors and has a suggestion on how I should proceed. 

 

best regards

Lars Jäger
