Hello! After trying cloudComputer example i'm trying to implement my own schedule distributor, but now i'm facing heap space error, but i see that it does distribute some work orders. Here's the console error: ------------------- 17:05:02.776 [main] INFO o.d.p.core.solver.DefaultSolver - Solving started: time spend (255), score (null), new best score (null), random seed (0). 17:05:02.821 [main] DEBUG o.d.p.c.c.g.DefaultGreedyFitSolverPhase - Step index (0), time spend (309), score (0hard/0soft), initialized planning entity ([Engineer-5]). 17:05:02.822 [main] DEBUG o.d.p.c.c.g.DefaultGreedyFitSolverPhase - Step index (1), time spend (310), score (0hard/0soft), initialized planning entity ([Engineer-4]). 17:05:02.824 [main] DEBUG o.d.p.c.c.g.DefaultGreedyFitSolverPhase - Step index (2), time spend (311), score (0hard/0soft), initialized planning entity ([Engineer-3]). 17:05:02.824 [main] DEBUG o.d.p.c.c.g.DefaultGreedyFitSolverPhase - Step index (3), time spend (312), score (0hard/0soft), initialized planning entity ([Engineer-2]). 17:05:02.825 [main] DEBUG o.d.p.c.c.g.DefaultGreedyFitSolverPhase - Step index (4), time spend (313), score (0hard/0soft), initialized planning entity ([Engineer-1]). 17:05:02.825 [main] INFO o.d.p.c.c.g.DefaultGreedyFitSolverPhase - Phase constructionHeuristic ended: step total (5), time spend (313), best score (0hard/0soft). 17:05:03.020 [main] DEBUG o.d.p.c.l.DefaultLocalSearchSolverPhase - Step index (0), time spend (508), score (0hard/0soft), best score (0hard/0soft), accepted/selected move count (1000/1000) for picked step ([Engineer-3] => [WorkOrder-12]). 17:05:03.315 [main] DEBUG o.d.p.c.l.DefaultLocalSearchSolverPhase - Step index (1), time spend (803), score (0hard/0soft), best score (0hard/0soft), accepted/selected move count (1000/1703) for picked step ([Engineer-4] => [WorkOrder-8]). 17:05:03.736 [main] DEBUG o.d.p.c.l.DefaultLocalSearchSolverPhase - Step index (2), time spend (1224), score (0hard/0soft), best score (0hard/0soft), accepted/selected move count (1000/2657) for picked step ([Engineer-1] => [WorkOrder-8]). 17:05:03.951 [main] DEBUG o.d.p.c.l.DefaultLocalSearchSolverPhase - Step index (3), time spend (1439), score (0hard/0soft), best score (0hard/0soft), accepted/selected move count (1000/4315) for picked step ([Engineer-5] => [WorkOrder-9]). 17:05:04.251 [main] DEBUG o.d.p.c.l.DefaultLocalSearchSolverPhase - Step index (4), time spend (1739), score (0hard/0soft), best score (0hard/0soft), accepted/selected move count (1000/9309) for picked step ([Engineer-2] => [WorkOrder-9]).

Custom UI to create rules and inserting them via REST API

by benq2188

Hi everyone, I would like to implement an Expert System which I can have my own UI to generate user defined rules, and I am planning to use REST API to insert/update/delete the rules,which are in the guvnor repository. Inside the guvnor, I would like to store my rules in .drl format. So I was wondering two thing: - Is that possible to create a brl file in XStream xml format as output of the UI, and store it in the repository as .drl format?. (I know the conversion from .brl to .drl is possible by using BRDRLPersistance object.) If it is possible then which object is the key point to create it from the "package org.drools.ide.common.client.modeldriven.brl"? -Another problem, by using REST API I can update and retrieve an asset in text/plain format, however I could not succeed to insert new asset into repository by using POST method. So how can I insert a new .drl rule into repository via REST. I will appreciate if you have some sample code for any of them and will be greatful for any help, Thanks, Bengi. -- View this message in context: http://drools.46999.n3.nabble.com/Custom-UI-to-create-rules-and-inserting...

Planner: localSearch > unionMoveSelector

by Michiel Vermandel

Hi, If I have a default unionMoveSelector in my configuration: <unionMoveSelector> <...MoveSelector/> <...MoveSelector/> <...MoveSelector/> ... </unionMoveSelector> then is the next move selected by random amongst the different move selectors. I think I can understand that from the manual, though want to verify that. Thanks Michiel ----------------- http://www.codessentials.com - Your essential software, for free!

by Binyala, Krishna Gopal IN BLR SISL

Hello, I am new to drools community... I want to develop an expert system for medical application using drools. can you please let me know how to use history data in drools... Because as far as i know we have to keep all the data in the working memory to access. How should i implement such system? Would be better if you can provide some reference to existing expert system implemented using drools. Thanks in advance.

DSL Translation

by prashantmirajkar＠gmail.com

In my project coding standard is as follows class members names as nameWithEachWordWithFirstLetterUpperCase and related getters and setters have getNameWithEachWordWithFirstLetterUpperCase and setNameWithEachWordWithFirstLetterUpperCase respectively. While using the DSL unlike ucfirst which converts first letter to upper case and rest to lower case, I want to have only first letter converted to upper case leaving other letters as they are. How can it be achieved? I am using drools 5.3.3 thanks in advance, Prashant -- View this message in context: http://drools.46999.n3.nabble.com/DSL-Translation-tp4021842.html Sent from the Drools: User forum mailing list archive at Nabble.com.

Dedication to Wolfgang Laun - Thank You

by Reinis

I want to thank you all. You, the members of drools community, for making this platform alive by giving away your knowledge and contributing the development of drools by sharing your thought and inducing the discussion. You, the developers of drools, for having ability to make it work and for actually making it work! And this time I want to say a special thanks to you, Wolfgang Laun, for being selfless, humble and having the gift of explaining things not because you're a doctor (of math btw) but because you have it down pat. And I thank you for sacrificing a lot of your private time to help me to solve my drools problem. So cheers to you, Wolfgang - a scientist, a mentor, a friend. Reinis

Duration rule attribute

by starfish15

Hello, A project is trying to weigh between BLAZE & DROOLS. N am a Drools FAN personally, since w/o doubt OPEN SOURCE always ROCKS. ;-) It was mentioned that in BLAZE there is a manner in which they decide on the rules validity period. Though even i mentioned that the same definitely exists in Drools as well. Since i had read a bit about. However, i did get confused with a part of the thing. 1. It was asked that in Drools will the rules be able to be valid for up til a year. Cause it seems in Blaze it is possible to change the validity till a year as well. 2. If yes, then i would appreciate if an example is given for the same Kindly help with this.

Error selecting order decrease

by André Fróes

Hello there, i'm getting this error: ------------------- 11:26:50.394 [main] INFO o.d.p.core.solver.DefaultSolver - Solving started: time spend (187), score (null), new best score (null), random seed (0). Exception in thread "main" java.lang.IllegalStateException: The selectionOrder (DECREASING_DIFFICULTY) can not be used on a PlanningEntity (com.swa.planner.domain.CloudProcess) that has no support for difficulty sorting. Check the @PlanningEntity annotation. at org.drools.planner.core.heuristic.selector.entity.PlanningEntitySelector.validate(PlanningEntitySelector.java:53) at org.drools.planner.core.heuristic.selector.entity.PlanningEntitySelector.phaseStarted(PlanningEntitySelector.java:45) at org.drools.planner.core.constructionheuristic.greedyFit.selector.GreedyPlanningEntitySelector.phaseStarted(GreedyPlanningEntitySelector.java:41) at org.drools.planner.core.constructionheuristic.greedyFit.DefaultGreedyFitSolverPhase.phaseStarted(DefaultGreedyFitSolverPhase.java:111) at org.drools.planner.core.constructionheuristic.greedyFit.DefaultGreedyFitSolverPhase.solve(DefaultGreedyFitSolverPhase.java:57) at org.drools.planner.core.solver.DefaultSolver.runSolverPhases(DefaultSolver.java:190) at org.drools.planner.core.solver.DefaultSolver.solve(DefaultSolver.java:155) at com.swa.planner.domain.CloudTest.main(CloudTest.java:51) ------------------------- I know why it is happening though (at least i think so), but will I have to implement the comparator to every planner I do or is there any other way to make it work? I'm reproducing the example from the guide, when it passes the drools rules it gives that message. I didn't implement CloudComputerStrengthComparator neither CloudProcessDifficultyComparator, will I have to implement those so this example works?
