virtualinherited |
This method is called when a solution is found.
It asserts whether the solution is valid. A value of false indicates that the solution should be discarded.

Just after refuting or applying the decision, apply is true after Apply.
This is called only if the Apply() or Refute() methods have not failed.

|
virtualinherited |
This method is called when a valid solution is found.
If the return value is true, then search will resume after. If the result is false, then search will stop there.
