Re: [rules-users] Unexpected, Unclear, Unperiodic error
Are the admin module and user module running in the same box? Can you access the package's URL from user's side? The error is clear, the kagent is getting a HTTP-502 error when it tries to read the package binary. Maybe a network configuration issue?

Re: [rules-users] Optaplanner - Multiday / Periodic Vehicle Routing Problems
On 15-05-13 03:35, Raoul Cousins wrote: I am interested in solving periodic vehicle routing problems and other multi-day (but static and deterministic) vehicle routing variants. These are similar to standard VRP except that not every customer is visited each day. In some variants, the days to visit each node are chosen from some predefined schedules; in others, each node has to be visited a specific number of times over the course of several days. Would Optaplanner be a good choice to model such problems? I know it's not a very well-defined question, but I'm wondering if there would be any serious difficulties modeling this type of problem before I dive into the programming. Definitely :) It's just a matter of choosing your class design wisely. Just like the VRP example: - Use a single PlanningEntity Visit, which represents 1 stop at a customer. - Use a single PlanningVariable previousAppearance, which is a Visit or a VehicleSingleDayTrip (instead of a Vehicle) The difference with the example is that the anchor of a chain (see "chained variables" in documentation) is not a Vehicle, but a VehicleSingleDayTrip. A VehicleSingleDayTrip is the combination of a Vehicle and a Day. The rest are just score constraint rules: - "days to visit each node are chosen from some predefined schedules" - "each node has to be visited a specific number of times over the course of several days" Thank you! ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users

[rules-users] Drools Fusion Dropping Events?
I've been working to load test Drools 5.3 to determine if its a fit for a project. As part of the test I programmatically insert events as rapidly as possible; an example, my earlier test inserted 10k events in about 300ms. There is currently a single rule which reads the event and stores the event's value into the only fact in Drools. I'm very happy to report, and I'm sure it will be no surprise to anyone, that the engine processes all the events in roughly 1 sec. However I have noticed that any large number of events (~1000) usually sees that a small number of events don't get processed. I think after 10k events as many as 7 appear to have gone unprocessed. If 100 events are inserted, rather than 10k, no events get disregarded. Being new to Drools I can easily accept that my java code or DRL code is off or unoptimized in some way. However not knowing how Drools does its magic I'm currently inclined to think that Drools gets swamped (10k in 300ms is a lot) and a few events get dropped so Drools can keep operating. Is this a known or expected behavior from Drools? If not I am happy to post my code, it is similar to the other code sets I've posted in the last few days. I'm still new to Drools and trying to learn its behavior so any insight or enlightenment is greatly appreciated.

Re: [rules-users] Drools Fusion Dropping Events?
What you describe is definitely not expected behaviour - it's more like that race condition (or another one) already being in 5.3. Posting your code might be a good idea ;-) -W On 16/05/2013, Jason Barto jason.p.ba...@gmail.com wrote: I've been working to load test Drools 5.3 to determine if its a fit for a project. As part of the test I programmatically insert events as rapidly as possible; an example, my earlier test inserted 10k events in about 300ms.
