SCIP：如何比较两个SCIP_SOL的目标值？

Question

Is there a function that can compare two SCIP_SOLs and determine whether one SCIP_SOL is more optimal than the other?

I am hoping to use this in a branching rule using the solutions in the solution pool.

Answer 1

To get the objective value of a solution you need to call SCIPgetSolOrigObj() . SCIP will automatically store the best found solution - call SCIPgetBestSol() to get it.

There is no such thing as a "more optimal" solution. If you want to compare solutions based on something other than their objective values you need to implement that metric yourself.
