Upgrade to 6.0.0.CR5 (follow the upgrade recipe txt)
and take advantage of the new feature called "shadow variables" (see
docs).
Also see the VRP with timewindows example for an implementation that
uses shadow variables :)

Hi,
Is it possible to provide more out of the box optimisers and solvers as part
of OptaPlanner.
Also add functionality for simulations (Monte Carlo) which would be a good
addition and fit.

Yes, we're trying to add more every major release.
For 6.1 we 'll probably add the CH's cheapest insertion and regret
insertion.
If you want to add one
After several tries and jar additions to war file I got more logs on the

I fixed the issue today, it was a subtle bug that I overlooked in the helper

session but I never used it. Therefore, when ever I called the
getKnowledgeSession method it built a new one, instead of returning the one

Where is Drools chance hosted?
Perhaps GA/GP can be a part of this?
Also Monte Carlo.
Maybe the current way to do is awkward? Is this covered in the
documentation?

Yes, here's a Genetic Algoritms prototype for OptaPlanner:

Results with GA's were poor, but we're
Option pricing and calculating the Greeks.
Why is GP/GA poor in performance? Best is to find a way to make it gain
performance. Otherwise what is the use of adding just for the sake of
adding it.
Also it would be good to have journaling / event sourcing option for the
engine along side logging.
On a somewhat related note:
I have a rule, where the value of #getResult may match the constraint at
some point during the accumulation, but later on will result in a value that
does not match the constraint anymore.
So in my scenario, the LHS of the rule is true at some point during the
