Re: [rules-users] Planning Under Uncertainty

I'm adding support native for uncertainty to drools: the code is in a sub-project repository called "drools-chance". I'll probably commit an update next week, supporting the declaration of beans with distributions as fields. Full support in the rules, instead, will take some more time. I would lik

Re: [rules-users] Changeset does not monitor folder correctly

I wrote a small test for loading your drl files with different change sets, and both methods worked fine and the rules executed the same way for both. I don't have time today to do a more extensive test. my change sets are: http://drools.org/drools-5.0/change-set"; xmlns

[rules-users] Planning Under Uncertainty

Hi, Does Drools Planner support uncertainty / probabilistic planning? I've Googled, and only found a single reference, in the form of a research paper, "Reasoning with Uncertainty in Drools", which doesn't even appear to be publicly downloadable. If not, how difficult would it be to add? Regards

Re: [rules-users] Expiry of events not occurring for sliding window

Thanks for the quick turnaround. Hmm...ok, I added a sliding window to the CE you called (5s), but still, no expiry (and I removed the log instance to make sure there wasn't some oddness there). So, it seems there is there some implicit expiration that is greater than my 10s that I declared--it's

Re: [rules-users] Expiry of events not occurring for sliding window

Looking pretty quickly to the rules it looks like: $mih:InstanceHealth($id:id, $luid:name, $stat:stat ) from entry-point "stat-stream" Will match for every InstanceHealth without any time restriction, causing that your events will be never evicted . Cheers On Fri, Sep 23, 2011 at 1

[rules-users] Expiry of events not occurring for sliding window

I'll preface this by saying this may not be the correct way to do this, so suggestions welcome... For this example, the name can be something like 'collector1', 'collector2'. For each collector, there are normalized stats, like 'CPU', 'IO', etc. // Imports and other stuff dec

Re: [rules-users] CEP sliding window in the past

I can (belatedly) confirm that this works for this instance. We want to do averages and other accumulations in the future, so it won't be as applicable then. I looked at the source and it shouldn't be that difficult to implement that offset, so when that time comes when we need those different

Please follow Thomas' advice. That now.time worked in 5.1.1 was actually an "accident", as it contradicted the specs. I'm not sure whether this behaviour is going to be reinstated. If you do need to do the comparison on long (milliseconds since the epoch) values you'd have to do subObject.d

Re: [rules-users] Issue using global 'variable' with Drools 5.2 in DRL

If it a java.util.Date then drools supports comparing them out of the box so you can just do subObjcet.dateField >= now. Just make sure you don't mix up instances of java.util.Date and java.sql.Timestamp (eg if you have jpa code fetching object from the db) as sun in their wisdom made it that y
