Combining Drools Expert and Planner
by Phani Saripalli
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.
Thank you :)

Hello,
Is there any guidance about the domain model of the examination example?
The class InstitutionalWeighting has some properties that I cannot undestand
the purpose of them
Thank you

Use a difficulty comparator if you can: it's the easy variant.
A difficulty weight factory is needed only if you need the entire
Solution (not just the entity) to calculate the difficulty of a given
entity.
In the examples, look for *DifficultyComparator and
*DifficultyWeightFactory.

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".

Drools Planner - Vehicle Routing, but a little different
by jimirn
Hi,
I hope someone can tell me what I am doing wrong.
I am trying to kind of do the same as the Vehicle Routing example.
My domain is:
- Consultant (the person that will drive to a DeliveryPlace and spent some
time there, each Consultant has a max total time available)
- DeliveryPlace (the place where a Consultant will drive to and spent some
time making a delivery)
- Location (a Consultant has a home and a DeliveryPlace has a location)
So basicly there could be X Consultants who has to make deliveries to Y
DeliveryPlace's. And I want to figure out the best way of doing that.
Right now my code does not find any doable moves:
16:51:57.654 [main] INFO o.d.p.c.c.g.DefaultGreedyFitSolverPhase - Phase
constructionHeuristic ended: step total (0), time spend (86), best score
(0hard/0soft).
16:51:57.658 [main] WARN o.d.p.c.l.DefaultLocalSearchSolverPhase -
Cancelled step index (0), time spend (89): there is no doable move.
Terminating phase early.
16:51:57.658 [main] INFO o.d.p.c.l.DefaultLocalSearchSolverPhase - Phase
localSearch ended: step total (0), time spend (90), best score
(0hard/0soft).
Here is the source code, modified from the Vehicle Routing example:

Guvnor encoding issue
by Fernando Penagos
Hi everyone,
I'm working whit Drools 5.4.0 final and the last version of Guvnor (5.40
final). I'm using eclipse as IDE.
The problem is whit this kind of actions that i have to use in my rules:
$asegurado.agregarExamenDeAsegurabilidad( "TRANSCRIPCION COPIA DEL
RESULTADO DE LA ULTIMA MAMOGRAFIA (NO MAYOR A UN A*Ñ*O)" );
In this action the result is an insertion on an Array but if you observe
there is a 'Ñ' and when i run the test i get something like:
TRANSCRIPCION COPIA DEL RESULTADO DE LA ULTIMA CITOLOGIA (NO MAYOR A UN *
AÑO*)
So the rule is never true.
I've tried whit some advises in the forums like insert
"-Dfile.encoding=ISO-8859-1" (i try with UTF-8 and Cp1252 too) on the
arguments of the server i'm using to deploy guvnor but the problem remains
plus other like try to save the file with an specific encode.
I already try to adding and "encoding" parameter to the "kagent" like this:
String encoding = "UTF-8";
kagent.applyChangeSet( ResourceFactory.newClassPathResource(
"changeset.xml"),encoding);
But nothing seems to work. What am I doing wrong??
I hope you can help me and thank you all.

Drools 5.4.0 Final library problem
by Eric Davison
I am having a small problem, I have Drools 5.4.0.Final installed, I
have Eclipse Indigo, Java JRE 5.0(or JRE and JDK 1.6), and the Drools
Plugin. I am attempting to run the hello world example. So the
problem is I am getting this error:
org.drools.RuntimeDroolsException: Unable to load dialect

I understood this to be fixed in this version, so I firmly believe
that I have hosed something up here. I think I have just stared at it
too long.
I have validated that I have the following in the Installed Software
Tab of the Eclipse Installation Details: Drools Core 5.4.0.Final,
Drools Guvnor 5.4.0.Final, jBPMCore 5.4.0.Final, and jBPM Task
5.4.0.Final.
Also I have Drools Eclipse Plug-ins installed under the Plug-ins tab.
All of them are 5.4.0.Final
I have JAVA_HOME set to C:\Program Files\Java\jdk1.6.0_30 and it is
also in my Path %JAVA_HOME%\bin.
Also the compiler settings in Eclipse are set for 1.6, and ensured
that the jdk1.6.0_30 is part of the project. Also the Drools Library
is there and has drools-core.jar contained in it.
If you have any suggestions please send them my way.
Thank you,

"factorize" rules
by John Dujon
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. I apologize in advance if that does not make
sense, as I am new to drools
