Is there a way to debug my project monitoring if it passes by my rule? In my console i don't see the score of hard constraint of this rule: ---- rule "requiredWorktimeToFinish" when $engineer : Engineer($worktime : worktime) $requiredWorktimeTotal : Number(intValue < $worktime) from accumulate( WorkOrder ( engineer == $engineer, $requiredWorktime : requiredWorktime), sum($requiredWorktime) ) then insertLogical(new IntConstraintOccurrence("requiredWorktimeToFinish", ConstraintType.NEGATIVE_HARD, $requiredWorktimeTotal.intValue() - $worktime, $engineer)); end rule "hardConstraintsBroken" salience -1 when $hardTotal : Number() from accumulate( IntConstraintOccurrence(constraintType == ConstraintType.NEGATIVE_HARD, $weight : weight), sum($weight) ) then scoreHolder.setHardConstraintsBroken($hardTotal.intValue()); end ---- in my console it points no score ---- 17:02:49.009 [main] INFO o.d.p.core.solver.DefaultSolver - Solving started: time spend (127), score (null), new best score (null), random seed (0). 17:02:49.041 [main] DEBUG o.d.p.c.c.g.DefaultGreedyFitSolverPhase - Step index (0), time spend (164), score (0hard/0soft), initialized planning entity ([WorkOrder-7]). 17:02:49.042 [main] DEBUG o.d.p.c.c.g.DefaultGreedyFitSolverPhase - Step index (1), time spend (165), score (0hard/0soft), initialized planning entity ([WorkOrder-9]). 17:02:49.043 [main] DEBUG o.d.p.c.c.g.DefaultGreedyFitSolverPhase - Step index (2), time spend (166), score (0hard/0soft), initialized planning entity ([WorkOrder-8]). 17:02:49.045 [main] DEBUG o.d.p.c.c.g.DefaultGreedyFitSolverPhase - Step index (3), time spend (168), score (0hard/0soft), initialized planning entity ([WorkOrder-6]). 17:02:49.045 [main] INFO o.d.p.c.c.g.DefaultGreedyFitSolverPhase - Phase constructionHeuristic ended: step total (4), time spend (168), best score (0hard/0soft). 17:02:49.274 [main] DEBUG o.d.p.c.l.DefaultLocalSearchSolverPhase - Step index (0), time spend (397), score (0hard/0soft), best score (0hard/0soft), accepted/selected move count (1000/1000) for picked step ([WorkOrder-7] => [Engineer-5]). 17:02:49.592 [main] DEBUG o.d.p.c.l.DefaultLocalSearchSolverPhase - Step index (1), time spend (715), score (0hard/0soft), best score (0hard/0soft), accepted/selected move count (1000/1926) for picked step ([WorkOrder-8] => [Engineer-3]). 17:02:50.045 [main] DEBUG o.d.p.c.l.DefaultLocalSearchSolverPhase - Step index (2), time spend (1168), score (0hard/0soft), best score (0hard/0soft), accepted/selected move count (1000/3686) for picked step ([WorkOrder-6] => [Engineer-2]). 17:02:50.464 [main] DEBUG o.d.p.c.l.DefaultLocalSearchSolverPhase - Step index (3), time spend (1587), score (0hard/0soft), best score (0hard/0soft), accepted/selected move count (1000/7516) for picked step ([WorkOrder-9] => [Engineer-2]). 17:02:53.877 [main] DEBUG o.d.p.c.l.DefaultLocalSearchSolverPhase - Step index (4), time spend (5000), score (0hard/0soft), best score (0hard/0soft), accepted/selected move count (0/350227) for picked step ([WorkOrder-7] => [Engineer-4]). 17:02:53.877 [main] INFO o.d.p.c.l.DefaultLocalSearchSolverPhase - Phase localSearch ended: step total (5), time spend (5000), best score (0hard/0soft). 17:02:53.878 [main] INFO o.d.p.core.solver.DefaultSolver - Solving ended: time spend (5000), best score (0hard/0soft), average calculate count per second (72872).

Question about caching of MoveListFactory

by Michiel Vermandel

Hi, Is it possible to use caching on a custom created MoveListFactory? I mean, I created a custom MoveListFactory and configured it like this: <moveListFactory> <moveListFactoryClass>my.planner.solver.ProjectShiftFactory</moveListFactoryClass> </moveListFactory> I noticed that the createMoveList method is called upon every step. Though, if I get things right, in the case that the step did not result in a better score, the solution will not be cloned and thus (in my case) the calling of the createMoveList in the next step will result in exactly the same list containing the same object instances. I think it would be OK if the createMoveListis only called when a better score is reached and a cloneSolution will be executed (and thus my object instances get obsolete). 1) I hope my theory makes sense end if so my question is: can I cache the list on the level as described? 2) One more question about steps: if a step does not result in a better score, what happens then? - A new number of moves is launched up to the limit defined by minimalAcceptedSelection? But what is the difference with the previous step? Is it the fact that a "different" solution with the same score will be used as starting point of the new step (given that one uses tabu)?

Re: [rules-users] [JBRULES-3703] Error parsing negative numbers in decision table

by metatech

Hi, (Attempt #2 after registering to the mailing list ...). For some reason, I do not have permission to add a comment in JIRA. Please add this answer in a comment on the case JBRULES-3703. Thanks. =============== The reason of the exception is because the number is treated as a float, ie "-1.0". The workaround is to add a single quote before the number and it will work. =============== Lubos Pechac wrote > Compiling attached .xls table results in exception, K12 column contains > "-1".

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!

FW: Implementation of expert system

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.
