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

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.
True, but that applies for the other cloning events too (at least
the ones initiated by Planner).
In the 6.0 docs, the term "clone" has been replace by the term
"planning clone",
and it's expectations have been explained.
See 4.3.5.6. Cloning a Solution.
https://hudson.jboss.org/hudson/view/Drools%20jBPM/job/drools-planner/lastSuccessfulBuild/artifact/drools-planner-docs/target/docbook/publish/en-US/html_single/index.html#d0e2680
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?

Hi,
I think a planning solution gets cloned in two
different scenarios:
1) a better solution is found
2) the solver propagates from one solving phase to
another.
Is this right?
Currently this is right IIRC. But mix in multi-threading
for 6.1 or 6.2 and there will be more cases of cloning.
If so, how do I know (inside the cloneSolution()
method) if the 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.

[rules-users] planner: when gets a solution cloned?
Hi, I think a planning solution gets cloned in two different scenarios: 1) a better solution is found 2) the solver propagates from one solving phase to another. Is this right? If so, how do I know (inside the cloneSolution() method) if the clone is intended for a best-solution or a new working-solution?
