[Scip] A question regarding node selection

[Tue Christensen]

Hello SCIP list!

After having (re)read the Coloring example I have a question. In coloringplugins.c the following is stated

   SCIP_CALL( SCIPincludeNodeselBfs(scip) );
   SCIP_CALL( SCIPincludeNodeselDfs(scip) );
   SCIP_CALL( SCIPincludeNodeselEstimate(scip) );
   SCIP_CALL( SCIPincludeNodeselHybridestim(scip) );
   SCIP_CALL( SCIPincludeNodeselRestartdfs(scip) );

I am however puzzled as to which strategy is actually employed with these calls. Some kind of mixture of them? Just the first? Or the last? What decides which strategy is used?

Best regards,

Tue Christensen
