Re: [rules-users] [Drools Planner] Hard constraint appears to be ignored
Op 26-02-12 19:47, Reinis schreef: Hello, 1) TRACE It did actually crash! Good :) java.lang.IllegalStateException: The presumedScore (0hard/-860soft) is corrupted because it is not the realScore (0hard/-858soft). It's not crashing on the hard constraint difference, but that probably means it doesn't get there yet. Presumed workingMemory: Score rule (reward Resource consolidation) has count (44) and weight total (44). Real workingMemory: Score rule (reward Resource consolidation) has count (46) and weight total (46). But the rule causing it looks normal to me: rule reward Resource consolidation when $leftAssignment : Assignment($project : project, $leftResource : resource != null, $leftId : id) $rightAssignment : Assignment(project == $project, resource == $leftResource, id != $leftId) eval(new Duration(Math.abs($leftAssignment.getInterval().getStartMillis() - $rightAssignment.getInterval().getStartMillis())).getStandardDays() == 0) Looks good to me. What you could do is make a Assignment.getIntervalStartMillis() and Assignment( ..., $leftStartMillis : intervalStartMillis) and add that rightAssignment's startMillis should be then leftAssignment's $leftStartMillis to avoid the Math.abs and double counting of this constraint. then insertLogical(new IntConstraintOccurrence(reward Resource consolidation, ConstraintType.POSITIVE , 1, $leftAssignment, $rightAssignment)); end 2) drools version and planner version drools-core-5.3.1.Final Can you try TRACE with drools-core, drools-compiler and knowledge-api 5.4.0.Beta2? There was a working memory corruption bug fixed in drools 5.4 over 5.3, not sure if it made 5.3.1. drools-planner-core-5.3.1.Final (No need to upgrade planner itself at this time - as that will force you down the UpgradeRecipe.txt).

Hi Ge0ffrey, What do you mean by initial solution?

[rules-users] POJO accessors method in Drools facts
Hi,
i have some troubles to undestand how drools processes FACTS. I have a POJO
class resulted from an UnMarshal jaxb processing like this:
public MyClass {
protected String className = Class1;
public getClassName(){
return className;
}
public setClassName(String className){
this.className = className
}
}
Now i have to compose a drl file with a rule like this:
when
$Class : MyClass()
eval ($Class.getClassName() == Class1)
then
System.out.println(ok!!!);
end
This syntax doesn't rise errors BUT doesn't match the real name... no ok
message are printed.
when
$Class : MyClass (getClassName() == Class1)
then
System.out.println(ok!!!);
end
This syntax raises me a null pointer exception!!!
What's the right syntax?
Can i use the accessor methods building drools facts?
Thanks a lot!

Hi
I think that yo have to instanciate the object and insert it into the
working memory then you fire all rules like this :
bMyClass x= new MyClass();
ksession.insert(x);
ksession.fireAllRules();/b
it will work without problem !

Re: [rules-users] Drools facts using POJO accessor methods error
As soon as you use eval(), you are in Java-land where String
comparisons should not be made using ==.
There's nothing wrong with the second form, i.e., you can write (using
Drools 5.3.0)
MyClass (getClassName() == Class1)
although the simpler form is usually preferred:
MyClass( className == Class1 )

Re: [rules-users] jboss tohu
Hi Olfa, Eclipse indigo is an authoring environment, there's no deployment there, you just need to install the drools plugin from the jboss tools (see docs), create a rule project and include the tohu jars/rule files in the classpath. Once you're ready with your application, you can generate e.g. a war and deploy it in a drools-server running on jbossAS (again, drools-integration docs should help).

Maybe you would be better off leveraging Guvnor for the Rules Editing.

Re: [rules-users] [Drools Planner] Hard constraint appears to be ignored
Hello, I did all the suggestions from Geoffrey (thanks sir) and now the TRACE is failing with an additional rule: java.lang.IllegalStateException: The presumedScore (0hard/0soft) is corrupted because it is not the realScore (0hard/-1soft). Presumed workingMemory: Score rule (penalize late assignments) has count (11) and weight total (8). Score rule (reward Resource consolidation) has count (7) and weight total (7). Real workingMemory: Score rule (penalize late assignments) has count (11) and weight total (*7*). Score rule (reward Resource consolidation) has count (*8*) and weight total (*8*). The offending rules look like this: rule penalize late Assignments when $project : Project(kickOff != null, $kickOff : kickOff) $assignment : Assignment(project == $project) eval($assignment.getInterval().getStart().isAfter($kickOff)) then insertLogical(new IntConstraintOccurrence(penalize late assignments, ConstraintType.NEGATIVE_SOFT, new Duration($kickOff, $assignment.getInterval().getStart()).toStandardDays().getDays(), $assignment, $project)); end rule reward Resource consolidation when $leftAssignment : Assignment($project : project, $leftResource : resource != null, $leftId : id, $leftIntervalStartMillis : intervalStartMillis) $rightAssignment : Assignment(project == $project, resource == $leftResource, id != $leftId, intervalStartMillis= $leftIntervalStartMillis) eval(new Duration($leftAssignment.getIntervalStartMillis() - $rightAssignment.getIntervalStartMillis()).getStandardDays() == 0) then insertLogical(new IntConstraintOccurrence(reward Resource consolidation, ConstraintType.POSITIVE , 1, $leftAssignment, $rightAssignment)); end * If I comment the reward Resource consolidation rule out, the test case completes successfully. * Is there anything else I can try? br Reinis On 02/27/2012 09:46 AM, Geoffrey De Smet wrote: Op 26-02-12 19:47, Reinis schreef: Hello, 1) TRACE It did actually crash! Good :) java.lang.IllegalStateException: The presumedScore (0hard/-860soft) is corrupted because it is not the realScore (0hard/-858soft). It's not crashing on the hard constraint difference, but that probably means it doesn't get there yet. Presumed workingMemory: Score rule (reward Resource consolidation) has count (44) and weight total (44). Real workingMemory: Score rule (reward Resource consolidation) has count (46) and weight total (46). But the rule causing it looks normal to me: rule reward Resource consolidation when $leftAssignment : Assignment($project : project, $leftResource : resource != null, $leftId : id) $rightAssignment : Assignment(project == $project, resource == $leftResource, id != $leftId) eval(new Duration(Math.abs($leftAssignment.getInterval().getStartMillis() - $rightAssignment.getInterval().getStartMillis())).getStandardDays() == 0) Looks good to me. What you could do is make a Assignment.getIntervalStartMillis() and Assignment( ..., $leftStartMillis : intervalStartMillis) and add that rightAssignment's startMillis should be then leftAssignment's $leftStartMillis to avoid the Math.abs and double counting of this constraint. then insertLogical(new IntConstraintOccurrence(reward Resource consolidation, ConstraintType.POSITIVE , 1, $leftAssignment, $rightAssignment)); end 2) drools version and planner version drools-core-5.3.1.Final Can you try TRACE with drools-core, drools-compiler and knowledge-api 5.4.0.Beta2?

Re: [rules-users] Constants
@Davide, there is *nothing* in Drools that is a full-fledged replacement for eitherr #define LIMIT 100 as in C, or const magic = 4711; as in Pascal, or..., or... Any modern programming language has this facility, and templates are no replacement, and globals still need Java code for their initialization prior to the insertion of any facts. @Richard Using some sort of parameter fact is another workaround, although this requires an additional CE in rules requiring such a constant. Also, a simple Java class containing just global final statics could alse easily (Java-)compiled and deployed with DRL packages importing these constants.
