Re: [rules-users] KnowledgeAgent to update knowledge base built with Guvnor pkg
Thank you very much for the detailed explanation, things are clearer now. I would have liked to be able to initialize the KA with an empty KB but I need to be able to set the configuration options for it and for now I don't see how that is done. Can the options, like STREAM mode be set when creating the KB from the KA? Otherwise I will continue to re-create the environment before running a session since for now it is the only option that works.

Re: [rules-users] KnowledgeAgent to update knowledge base built with Guvnor pkg
The options are set at the KB level, way before rules etc.. are added. So yes, you can initialize an empty KB and use changesets to add rules dynamically later. Notice this: KnowledgeBase knowledgeBase = KnowledgeBaseFactory.newKnowledgeBase(conf); /* knowledgeBase.addKnowledgePackages(builder.getKnowledgePackages()); */ return knowledgeBase; You can define a changeset in a file, or you can create it programmatically.

Re: [rules-users] [Planner]
Mats Norén wrote Hi, I've got a really simple problem that I can't seem to fix. :-) I'm trying to use a simplified model for a room planning problem. The planning entity is a Topic and the planning variables are Room and TimeSlot. A Person is tied to a Topic as a moderator. Each Person can have multiple Topics as an interest. The hard constraints are that a Person cannot be moderator in two Topics at the same TimeSlot and that there cannot be multiple Topics in the same Room at the same TimeSlot. rule conflictingModeratorInSameTimeslot when $leftTopic : Topic($leftId : id, $leftTimeslot : timeSlot, timeSlot != null, $leftModerator: moderator) $rightTopic : Topic(timeSlot == $leftTimeslot, moderator == $leftModerator, id $leftId) then scoreHolder.addHardConstraintMatch(kcontext, -1); end rule multipleTopicsInSameRoomAndTimeslot when $leftTopic : Topic($leftId : id, $leftTimeslot : timeSlot, timeSlot != null, $leftRoom: room) $rightTopic : Topic(timeSlot == $leftTimeslot, room == $leftRoom, id $leftId) then scoreHolder.addHardConstraintMatch(kcontext, -1); end yep, that's like in the curriculum course scheduling example Mats Norén wrote The soft constraint that I have a problem with is that a Person has multiple Topics as interests and I would like to penalize the Solution with the number of Topics in the Persons interests collection with the number of Topics that are allocated at the same TimeSlot.

Re: [rules-users] Some Puzzles in planner
erere121 wrote Hello every one ,I study the drool.plannar recently and both tried the planner 5.5 and planner 6.0(optaplanner) to solve my problem. I found something puzzles: 1 Is there any big difference between planner 5.5 and planner 6.0. I run the same process in both planner 5.5 and planner 6.0 with the same config, I find planner 5.5 gives the solution with 19hard broken while planner 6.0 give the solution with 502hard broken ! I am not sure why it happens. 2 When I open the demo in optaplanner in eclipse, I find every scoreHolder.addConstraintMatch(); have the error like this:The method addConstraintMatch(kcontext，..) in the type SimpleScoreHolder is not applicable for the arguments (RuleContext, int), can anybody help me. 3 The problem has a solution which breaks no rules while both planner 5.5 and 6.0 never found it using the tabu search and hill climb search. I wonder is it right or is there any other global search method in planner. 1. That should not happen. Turn on enviromentMode FAST_ASSERT to validate you don't have any score corruption. 2. Sounds like your eclipse is using the wrong optaplanner-core jar on it's classpath to compile 3. It could be that there's no feasible solution (= 0 hard constraints broken) to your solution, but I 'd only start believing this if environmentMode doesn't find any score corruption. If it's a really tiny problem, you can use the configuration bruteForce to be 100% sure. (Note: Tabu search currently doesn't automatically scale down to tiny problems (= less than 10 planning entities), you have to manually lower the planingEntityTabu configuration setting. -- View this message in context: http://drools.46999.n3.nabble.com/Some-Puzzles-in-planner-tp4023580p4023659.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

[rules-users] Camel get ksession results
Hi, I'm using Drools integration with Camel and have to be able to get the objects that were validated by a rule in a stateless ksession later in the Camel route. My camel-server.xml has something similar to this: policy ref=droolsPolicy bean ref=createList / to uri=drools:node1/ksession1 / bean ref=afterRules / /policy in the createList bean I create a list of java objects and call CommandFactory.newBatchExecution(commandList); My Drools rule responds as expected. So far so good. But then later when execution reaches afterRules bean, the exchange body has empty lists for both facts and results. What I want at this point is to be able to get all the objects which were compatible with the rule (a simple sysout). The ones that didn't match the rule, are simply disposed. How can I solve that?

[rules-users] How to find rules, that use special fields in their Condition
Hi,
the following code traverses rules and their conditions. However, I did not
find a method to find conditions, that match over a certain field of a
declared class. I know, that the rule API should be hidden for good reasons
(Mark Proctor).
for(Rule ruleDef : kb.getKnowledgePackages().iterator().next().getRules()) {
for(RuleConditionElement rce :
((RuleImpl)ruleDef).getRule().getLhs().getChildren()) {
for(Map.EntryString, Declaration entry :
rce.getInnerDeclarations().entrySet()) {
??
Thanks, Marc

successfully, if I insert 150k events, I receive a ConsequenceException
caused by an NPE. Being new to Drools I must be doing something wrong, can
anyone please provide some guidance?

Re: [rules-users] Does Drools have memory address equals check operator
There's a paragraph or two about assertion modes, i.e., equality or identity in the Drools Expert manual. Note that inserting identical objects is against the meaning of fact, and that may also be true for objects that are equals(). For explicit control about the distinction between == and equals() wrap your condition code in eval(), where Drools does not interfere. -W On 03/05/2013, Sean Su sean.x...@gmail.com wrote: In another word, do we have operator doing what object == object in Java? thanks Sean ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
