I was wondering now if I can achieve the same with the drools rule file.
That's a bit harder, but not that hard.
Look in the Drools Planner manual for setRuleBase() (as an alternative
to using scoreDrl's in your SolverConfig.xml)
and look in the Drools Expert manual on how to create a
A corrupted score normally indicates a problem with the Move
implementation (or sometimes the score drl).
Basically this happened: for a number of moves, it did the move,
calculated the score and undo the move.
One of those move was associated with a score -10hard/0soft, that was
the best
Probably you forgot to notify the workingMemory.update in the doMove method:
public void doMove(WorkingMemory workingMemory) {
FactHandle factHandle = workingMemory.getFactHandle(activity);
activity.setAssignee(...);
workingMemory.update(factHandle, activity);
}
Do you want a new Jira issue raised for this?

Hi Michael,

But wouldn't the KnowledgeAgent be created as part of an application, by
application code. Why should it ever be recreated, changes in the knowledge
base or no changes?

Wolfgang is correct. Just an additional distinction that is important:
expiring an event is different then retracting an event/fact. Imagine that
there was a computer with infinite processing power and infinite memory. In
that case, we would never need to expire any events, we would just keep

In your doMove you're doing:
crew.addActivity(activity);
remainingActivities.remove(activity);
If crew and/or remainingActivities are used by your score rules, the
working memory should be notified of their changes.
That's causing the corruption

I think it will work fine for currencies, perhaps only 100 messages per

You need to analyze if you can handle 100k objects creation per second in
java first.. I think that will be the first bottle neck :)

And before the object creation, you'll have to get the data into your system...

ok bad example.
Are there any metrics on drools performance that I could reference?

No such thing, just like there is no metrics on the performance of a
C program. Reason: it depends.
Before you invest heavily, rig up a set of rules according to what
you'll need, create some data and benchmark *your application*, or at
least as close as possible. The speed of Drools for solving
Unfortunately, it is a hard question to answer, because it is the same as
asking: what is the performance of a database (postgreSQL, Oracle, etc)? It
is totally dependent on the data you load, the queries you write and the
indexes you use.
So you need to think about overhead and pay-off of
