Perhaps GA/GP can be a part of this?

Yes, here's a Genetic Algoritms prototype for OptaPlanner:
  https://github.com/elsam/optaplanner
Results with GA's were poor, but we're going to add it sooner or later.
Here's the relevant issue to add it:
  https://issues.jboss.org/browse/PLANNER-154

Also Monte Carlo.

Maybe the current way to do is awkward? Is this covered in the documentation?

simulation isn't covered in the documentation.

What kind of simulation do you want to do?
What's the problem definition?

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 yourself, start by looking at
DefaultLocalSearchSolverPhase.java.

Simulation support would be great indeed - but the requirements aren't
clearly definied yet (feedback, examples or use cases welcome).

It's already possible to do simulation + optimization
by doing the simulation inside the score function (for example by
running a monte carlo simulation)
and doing the optimization with optaplanner.

drools-chance (very experimental currently) has a lot of constructs that
can help in simulation (bayes stuff etc).
