--------------------------------------------------------------------
It needs to be fixed on an architectural level:
maybe each Score should have an unitialized entity count which counts as a higher score
level (harder than hard).
Planner must manage that unitialized entity count itself, it shouldn't force the users
to deal with that.

Key: JBRULES-3577
URL: https://issues.jboss.org/browse/JBRULES-3577
Project: Drools
Issue Type: Bug
Security Level: Public(Everyone can see)
Components: drools-planner
Reporter: Geoffrey De Smet
Assignee: Geoffrey De Smet
DefaultSolver.runSolverPhases() will go through each phase, and will revert
the changes if they're not better. Or, more exactly, here are lines 191-193:
if (it.hasNext()) {
// solverScope.setWorkingSolutionFromBestSolution();
}
Now, if this involved setting the planning variables for the first time,
those will be reverted.
