[rules-users] planner environmentMode

[Michiel Vermandel]

Hi Geoffrey,

Thanks for your response.
Indeed I use Simulated Annealing with maximumSecondsSpend. So that explains the randomness of the LocalSearchPhase.
Sorry for not remembering.

Can you tell me please some more on "Use of HashSet in your Solution class"?
Do you mean a planning fact as a HashSet?
I have some HashMap fields in my Solution (which I also pass in the cloneSolution method) but non of these fields are planning variables/entity.

Regards,
Michiel

Common causes:
- Use of HashSet in your Solution class.
- Combination of Simulated Annealing with time spend termination
    (clearly documented in manual)
