Hello,
Is there any guidance about the domain model of the examination example?
The examination example has a problem description, problem size and
domain model documentation:
http://docs.jboss.org/drools/release/5.4.0.Final/drools-planner-docs/html_single/index.html#d0e1267
It even includes a class diagram of the model
The class InstitutionalWeighting has some properties that I cannot undestand
the purpose of them
InstitutionalWeighting is basically a set of parameters of a single
dataset to dynamically configure when the constraints active and how
big their penalty is.
For example: if periodSpreadLength = 5, than students want to have 5
free periods between 2 exams.
Some universities use periodSpreadLength = 5, others
periodSpreadLength = 3, etc, but they all use the same drl file (in
the current implementation).
// Exams which share students have to few periods between them
rule "periodSpread"
when
$institutionalWeighting :
InstitutionalWeighting(periodSpreadPenalty != 0)
$topicConflict : TopicConflict($leftTopic : leftTopic,
$rightTopic : rightTopic)
$leftExam : Exam(topic == $leftTopic, $leftPeriod : period)
$rightExam : Exam(topic == $rightTopic, $rightPeriod :
period)
eval(Math.abs($leftPeriod.getPeriodIndex() -
$rightPeriod.getPeriodIndex())
($institutionalWeighting.getPeriodSpreadLength()
+ 1))
then
insertLogical(new IntConstraintOccurrence("periodSpread",
ConstraintType.NEGATIVE_SOFT,
$topicConflict.getStudentSize() *
$institutionalWeighting.getPeriodSpreadPenalty(),
$leftExam, $rightExam));
end
Thank you

Re: [rules-users] planning difficulty problem
[I locally answered this question last time already, but it looks like my mail never reached the mailing list due to a local misconfiguration at the time] If it's in anything like the nurse rostering example, I would presume the following domain: - Planning entity: ShiftAssignment. There are 9 (3 shifts for 3 hospitals) - Planning variable: ShiftAssignment.get/setDoctor() - Planning values for that variable: 10 doctors So Planner will put a doctor in each of those 9 ShiftAssignments and 1 doctor won't be assigned to any shift. Actually, Planner might assign the same 2 doctor to 2 different ShiftAssignments if none of the constraints are broken (such as no 2 ShiftAssignements at the same time for the same doctor). See nurse rostering example. Play around with it. Take a look at this video about contentious planning with nurse rostering: http://blog.athico.com/2012/08/continuous-planning-video.html Mentally replace nurse with doctor and department with hospital.

[rules-users] Combining Drools Expert and Planner
Hi. Is it possible to combine Drools expert and planner to solve NP problems (or some kind of model checking). For example, I have a model described as a .drl file declare Project x : int end And, then I have a constraint (or rule) - something like this - rule Rule on x agenda-group Group 2 dialect mvel no-loop true when P : Project(P.x 5 P.x 7) then System.out.println(Rule satisfied); end Is it possible to obtain a value propagation mechanism by combining with Planner, by which I finally get a value for x as 6 ? I am working on model checking for models that have various constraints, on boolean, int, real, strings, container types and also on types that are similar to C structs. There is hardly any reasoner/solver that does model checking for constraints on such a varied types of datatypes. I checked planner, but defining planning variables and stuff on score generation seemed to me a bit new and confusing.

Re: [rules-users] Capturing DDLs from Guvnor
What did you mean log the DDLs? I thought you needed the DDL to create the JCR schema on different RDBMS's - hence I pointed you to the DDL JackRabbit uses. IIRC you can enable logging of SQL statements (DDL and DML) on Oracle (and probably other RDBMS's) if you want to log the DDL JackRabbit uses - but I suspect it'll be the same as the DDL files I pointed you to. If you are expecting a schema that shows a table for Asset, Rule, Enum etc etc you will have along time looking. If JackRabbit is configured to store it's internal data-structures in a RDBMS it uses (and I quote the JavaDocs) ...a simple custom binary serialization format and a very basic non-normalized database schema If you want to use a RDBMS not natively supported I suspect you'll need to write your own DatabasePersistenceManager, but this is out of the scope of the Drools mailing lists and questions should be submitted to the JackRabbit mailing lists.

There is hardly any reasoner/solver that does model checking for constraints on such a varied types of datatypes. I checked planner, but defining planning variables and stuff on score generation seemed to me a bit new and confusing.

Re: [rules-users] Which proper way to test for Event expiration in Drools Fusion?
Found solution! Obviously it was me being stupid and not realizing I was using Drools 5.4.0.Final while still referring to old documentation of 5.2.0.Final. In the updated documentation for Drools Fusion 5.4.0.Final, this box is added for 2.6.2. Sliding Length Windows: Please note that length based windows do not define temporal constraints for event expiration from the session, and the engine will not consider them. If events have no other rules defining temporal constraints and no explicit expiration policy, the engine will keep them in the session indefinitely. Therefore the 3rd requirement I originally enlisted of You must define temporal constraints between Events is obviously NOT met because I now understand Sliding Length Window in Drools 5.4.0.Final: Message() over window:length(1) are indeed NOT a definition of a temporal constraints for event expiration from the session. Updating this answer hopefully somebody will find it helpful (and Stackoverflow original reference updated as well). Also, just so for your know, me being stupid actually for relying on googling in order to reach the doc, and sometimes you don't get redirected to the current release documentation, so it seems...

Re: [rules-users] Deserialzation Error running test example
So, what versions do I use? I downloaded the guvnor from Jboss web site. 5.4.0 final and I got the example code from github repository. -- View this message in context: http://drools.46999.n3.nabble.com/Deserialzation-Error-running-test-example-tp4019874p4019882.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] factorize rules
Hello, I am trying to make my rules more readable and wonder wether or not we can factorize rules for a particular ruleflow-group. As an example, I would like to convert this: // begin rules rule Rule 1 ruleflow-group work when condition 0 condition1 then doSomething(); rule Rule 2 ruleflow-group work when condition0 condition2 then doSomethingElse(); // end rules to the following // begin rules pre_conditions_for_rules ruleflow-group work condition0 rule Rule 1 ruleflow-group work when condition1 then doSomething(); end rule Rule 2 ruleflow-group work when condition2 then doSomethingElse(); end // end rules Thank you for your time.
