[rules-users] planner: when gets a solution cloned?

[Michiel Vermandel]

>Why would you need to know that?

Well, if I understand everything correctly, a "Best-solution clone" is needed just to remember/represent that state of the solution.
It does not have to do anything anymore, therefor some data should not be copied and/or initialized upon cloning.
It might be "not optimal" design that drives me to initializing stuff upon cloning, but anyway I think there might be more scenarios where it is useful to know if the solution object is the working solution or a best solution.
Right?

Michiel

Currently this is right IIRC. But mix in multi-threading for 6.1 or 6.2 and there will be more cases of cloning.

        clone is intended for a best-solution or a new working-solution?

Why would you need to know that? Would it alter your cloning behavior somehow?

It's probably hackable through BestSolutionRecaller, but it will
    give you a hard time when upgrading to 6.0 if you do hack it there.
