Re: [rules-users] Optaplanner rule to assign employee only to shift when he/she has the skills
If you copied the employee rostering example, you can click on the shifts to assign them to another employee. Before you do that, write down the score. Then use the trick above the reassign the shifts as you believe it's better. Now write down the score again. Is the score better?

Re: [rules-users] Drools 5.5.0 - Execution Performance
Thanks for your fast reply ... I did not retract the facts after each cycle, I inserted the facts within the loop and fired rules afterwards ... but i repeated the test with fireing rules and retract facts for each cycle - the effect is the same ... the elapsed time is nearly the same (about 2 sec for 600 facts) and it gets faster after the first loop cycle Working memory was in Identity mode (which is default) but I also tried with equality ... same result I changed mode this way: RuleBaseConfiguration ruleBaseConfiguration = new RuleBaseConfiguration(); ruleBaseConfiguration.setAssertBehaviour(RuleBaseConfiguration.AssertBehaviour.IDENTITY); should be correct or am i wrong? BatchExecution resulted in about 2 sec total time as well ... so it seems there is no difference ... It would be great if the rule engine somehow learns over time and assertion gets faster but I am still not sure whether this is because asserting same instances of facts -- View this message in context: http://drools.46999.n3.nabble.com/Drools-5-5-0-Execution-Performance-tp4026936p4026942.html Sent from the Drools: User forum mailing list archive at Nabble.com. ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
Re: [rules-users] Optaplanner rule to assign employee only to shift when he/she has the skills
I have based my code on the nurse rostering example. But I have completely stripped out the GUI part. But I have found the error. My rule was wrong. A rule that works for me is: rule alternativeSkill when ShiftAssignment($employee : employee, $shiftType : shiftType) not SkillProficiency(employee == $employee, shiftType == $shiftType) then scoreHolder.addHardConstraintMatch(kcontext, -1); end -- View this message in context: http://drools.46999.n3.nabble.com/Optaplanner-rule-to-assign-employee-only-to-shift-when-he-she-has-the-skills-tp4026879p4026943.html Sent from the Drools: User forum mailing list archive at Nabble.com. ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users

Re: [rules-users] Drools 5.5.0 - Execution Performance
Are creating a new ksession for each batch of insertions? Or using the same one? If the same one, are you deleting them after insertion? And as per wolfgang’s message, JIT might have a big impact for this. Mark On 25 Nov 2013, at 22:50, ch3xy igor.stri...@gmail.com wrote: Hello, first of all I'd like to mention that i am pretty new to Drools, so please be patient :-) We are using Drools 5.5.0. we have a knowledgeBase of about 500 rules and a pretty complex object structure. So far everything is working fine … at the moment we are testing the performance of the engine and we encountered a quite strange thing. We generated about 10 objects, inserted it into the session and measured time needed for execution of rules. To simulate a high number of facts, we inserted the same objects over and over again (100x, 1000x, 1x). When the first objects were inserted, the time of execution was about 100ms but for each iteration the execution got faster and faster (20ms, 10ms and later on even 1ms) .. Now my question: Are the objects somehow cached in the working memory, so that execution gets faster or does this increase of performance has an other reason? I read a few things about shadow facts which are not present anymore since Drools 5 and sync and async Rete and I think this could be a potential answer for my question, but I am not able to understand this completely. For me it is important to know whether the increase of performance is only due to the fact that we are inserting the same facts over and over again or if a significant increase of performance is still possible if facts are not identical? Can someone help me?

Re: [rules-users] Jetty NoSuchMethodError Lorg/eclipse/jdt/core/compiler/CategorizedProblem
I noticed this same error when attempting to use the Run Jetty Run eclipse plugin with Jetty 6.1.26. Changing it to use Jetty 7.5.1 fixed the problem. We still use version 6 on our test servers without a problem though so I just put it down to some classpath issue with the plug-in. --- Steven Williams On Wed, Nov 27, 2013 at 3:01 AM, captainrhino graeme.kitc...@axa-travel-insurance.com wrote: I am running some drools application code through Jetty and I get the following error.

[rules-users] Multiple rule violation
Hi, I have a problem scenario. I insert two facts - obj1 (on which rules needs to be validated, used in when part), - obj2 (to retrieve output, used in then part) Let's say there are two rules Rule1 and Rule2 for this fact type and both of them get violated. In this case I am getting only one instance of updated obj2. I need two instances of obj2 as both rules are violated. So, that I can perform operation on based on those. I have also seen on internet that DROOLS skips checking for other rules if any one gets violated. So, requirement is as 1. DROOLS should check for all rules (What is performance cost for this. Does fire all rules work this way?) 2. All instances of obj2 to perform actions accordingly (What is best way to do this. Should I insert an array of this type? If so please, say how to achieve this?)
