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
