Thank you for the advice.
I've downloaded 5.5.0.Beta1 and carried out the required update steps. BTW
the new selector system seems to be a giant leap forward.
First question: Given that I want to keep certain entities together, do I
still need to employ changeMoveSelector's? or should I only use pillars?
I
usually mix both:
<unionMoveSelector>
<changeMoveSelector/>
<swapMoveSelector/>
<pillarSwapMoveSelector/>
</unionMoveSelector>
Just try it out and use the benchmarker to find the best set for your
use case.
With respect to the pillarSwapMoveSelector, as in my example above, how do I
tell it I want to base the pillar on the planningVariable timeSlots? I tried
to add a valueSelector/planningVariableName but it doesn't work. I had a
look at the source code and it seems that the planningVariableName section
of the code has been commented out.
You mean you have multiple planning vars, but
only want to pillarSwap to
base on and affect 1 var (and ignore the other vars)?
The PillarSwapMoveSelectorConfig class doesn't support that yet,
but the PillarSwapMoveSelector class itself does.
Currently the PillarSwapMoveSelectorConfig always pillarSwaps around all
vars:
public MoveSelector buildBaseMoveSelector(EnvironmentMode
environmentMode, SolutionDescriptor solutionDescriptor,
SelectionCacheType minimumCacheType, SelectionOrder
resolvedSelectionOrder) {
...
Collection<PlanningVariableDescriptor> variableDescriptors =
leftPillarSelector.getEntityDescriptor()
.getPlanningVariableDescriptors(); // This should be a
singleton of just the variable you want
return new PillarSwapMoveSelector(leftPillarSelector,
rightPillarSelector, variableDescriptors,
resolvedSelectionOrder == SelectionOrder.RANDOM);
}
That class really needs something like this:
@XStreamImplicit(itemFieldName = "swapPlanningVariable")
private List<String> swapPlanningVariableList = null;
so you can do
<pillarSwapMoveSelector>
<swapPlanningVariable>timeSlot</swapPlanningVariable>
</pillarSwapMoveSelector>
Same story for SwapMoveSelectorConfig.
Pull requests welcome :)
Thanks,
Jason
