## Member Function Documentation

virtual bool CbcCompareBase::newSolution | ( | CbcModel * |  | ) | `[inline, virtual]`

Reconsider behaviour after discovering a new solution.

This allows any method to change its behaviour. It is called after each solution.

The method should return true if changes are made which will alter the evaluation criteria applied to a node. (So that in cases where the search tree is sorted, it can be properly rebuilt.)

Definition at line 45 of file CbcCompareBase.hpp.

virtual bool CbcCompareBase::newSolution | ( | CbcModel * | ,
|  | double | ,
|  | int |  |
