Re: [rules-users] [planner] getBestSolution not returning the correct Solution?
2. Question about the cloneSolution.
I have 3 properties in my Solution implementation.
ArrayList<Material> materials; // Problem Facts
ArrayList<ServiceRequest> serviceRequests; // Planning Entities
SimpleScore score;
In example, I noticed that Planning Entity is cloned but Problem Facts is
not cloned.
Why problem facts not cloned?
It's a waste of performance time: they don't
change during planning.
Only entity classes changes during planning.
The clone() method is called every time a new best solution is found (to
recall it later while the workingSolution proceeds).
This works even in the face of real-time planning, where the problem
facts look like they change during planning,
but actually the problem facts only change "in between" planning, not
during.
