We could reproduce the issue, it's now in a unit test:

Re: [rules-users] Nested negation constraints behavior change from Drools 5.x to 6.x

2014-02-27 Thread mikerod 
I made a basic jar that only depends on Drools.

All the rules do is output to standard out to demonstrate.
This can just be ran with:
`mvn exec:java -Dexec.mainClass="example.drools.TestingNestedNegation"`

This is with v6.0.1.Final; so switching this in the pom.xml to 5.6.0.Final,
for example, will cause the different behavior between the versions i.e.
changing 6.0.1.Final in pom.xml .

@Mark I looked at the link and he had a zip file.  I'm guessing a jar with a
main class in it is sufficient? drools-example-tests-1.0-SNAPSHOT.jar

  

Also, I am still using the now, legacy API for the kb and Stateful session. 
I tried to add the logback.xml config file, but it doesn't seem to work
quite so simply there.  That is likely due to me not reading up on the new
API yet...  I'm hoping the initial uplift to v6.x can just be to the legacy
API and migrate over later on.

I don't think the API choice would make this behavioral change in the rules
nonetheless.

Let me know what else would be helpful.

Please don’t post for answers, just hours after asking your question.

I expect it has not been exposed in spring 6.0.1. Did you check the spring xsd?

If it can’t be done from spring, you can probably still do it via the old 
external package builder .conf. You’ll need to google for details on how to use 
that.

For accumulates we removed the need for configuration and made them work via 
imports, I think we’ll do the same there too, rather than fix spring xml - then 
it won’t need any configuration either.

Re: [rules-users] sliding window question

2014-02-27 Thread lin.lin 
Hi 

   Thanks again for the pointers!!

   I modified the code but the sliding window rule does not seem to be
working as how I want it to be(copied shown in the following).  I injected 6
events, one event every 10 seconds, the first one is less than 90, the rest
are more than 90.  I am expecting getting 3 alerts at 4th event, 5th event
and 6 event. But instead I only get one alert.

  when 
not Reading( reading <= 90 ) over window:time( 30s ) from entry-point
ReadingStream
  then 
 System.out.print ("alert: Reading high for 30 seconds \n"); 

  
  So I used the other way as you suggested. It works and gives me 3 alerts.
However if I added the accumulate pattern (copied below) , no alert is
generated at all.  If I removed the first 3 patterns, just leave the last
pattern, it does print the average of last 30 seconds event every time when
a new event is injected. What else did I do wrong?

  when
  $r1: Reading( reading >90 ) from entry-point HeartrateStream
  $r2: Reading( reading > 90, this after[30s,30s] $r1 ) from
entry-point HeartrateStream
  not (Reading( reading <= 90, this after $r1, this before $r2 )
from entry-point HeartrateStream)
 $averg: Number() from accumulate( Reading ( $r:reading) over
windiw:time(30s) from entry-point HeartrateStream, average($r) )
  then
 System.out.print ("alert: Reading high for 30 seconds, average
reading"+$averg+"\n"); 


Thanks a lot!!!
Lin

If you can work it into some sort of unit test, we’ll fix it ASAP. If you look 
at:
"Re: [rules-users] NullPointerException with LeftTupleIndexHashTable.remove()”

You’ll see there he created a large project, which we then on the dev mailing

[rules-users] Nested negation constraints behavior change from Drools 5.x to 6.x

2014-02-27 Thread mikerod 
With both Drools v5.5.0.Final and v5.6.0.Final I observe a different behavior
than in both v6.0.0.Final and v6.0.1.Final.
in certain rules with negation wrapped around nested constraints.

I have tried to make the simplest rules to demonstrate the situation.

With a kb consisting of the following rules, which I have comments on that
describe what I've
found with the situation:

```
// Enabling this rule, makes "negation_over_nested" and
// "negation_distributed_partially_sharing" fire;
// without it they do not.
// 
// I think this is due to some shared structure
//  in the underlying subnetwork (I believe this is referred to as a
"segment").
// Perhaps it makes them "linked" in when otherwise they are being missed.

/**  *This is commented out, uncommenting causes different firing of other
rules*
rule shared_conjunct
when
(not (String() and Integer()))
then
System.out.println("shared_conjunct");
end
*/

// Won't fire with no wm facts UNLESS 
// it shares (I think) a node/subnetwork/segment with constraints 
// in a rule like "rule shared_conjunct" that DOES fire
rule negation_over_nested
when
  not ( (String() and Integer())
or 
(String() and Integer()))
then 
System.out.println("negation_over_nested");
end

// Won't fire with no wm facts
rule negation_distributed_partially_no_sharing
when
(not (String() and Long()))
and 
(not (String() and Long())) 
then 
System.out.println("negation_distributed_partially_no_sharing");
end

// Same situation as "negation_over_nested"
rule negation_distributed_partially_sharing
when
(not (String() and Integer()))
and 
(not (String() and Integer()))  
then 
System.out.println("negation_distributed_partially_sharing");
end

// DOES fire with no wm inserts.
// DOES NOT need "shared_conjunct" to work
rule negation_distributed_fully
when
((not String()) or (not Integer()))
and
((not String()) or (not Integer()))
then 
System.out.println("negation_distributed_fully");
end

```

--- 

This is the only 2 rules in the kb.  Running a session, with no facts
inserted and then firing all rules.

Drools v6.x output:
with "shared_conjuct" rule uncommented:
```
shared_conjunct
negation_over_nested
negation_distributed_partially_sharing
negation_distributed_fully
negation_distributed_fully
negation_distributed_fully
negation_distributed_fully
fired: 7
time elapsed: 0.0

```

with "shared_conjuct" rule commented out:
```
negation_distributed_fully
negation_distributed_fully
negation_distributed_fully
negation_distributed_fully
fired: 4
time elapsed: 0.0
done
```

I do note in the v6.x output, "negation_distributed_partially_no_sharing"
never fires, since it is specifically not sharing any
negated conjunt with the other rules.  This seems to correlate with whether
or not these rules fire.
Also, I realize my terminology is slightly off.  I think this is an issue
with rules having shared "segments", where 
one of these segments that is shared is the negation subnetwork introduced
in "shared_conjunct".

I also note that "negation_distributed_fully" always fires, independent of
any potential "segment" sharing.

As I mentioned in a comment on "shared_conjuct", I'm thinking this relates
to the newer PHREAK algorithm vs the original ReteOO.

Is this expected?  Is there something incorrect about the structure of the
negation rules?
Perhaps I have stumbled upon a defect?

I have not had time to do any sort of deeper debugging into the issue, if I
find out more info, I'll post it up here.

p.s. I know the types are not meaningful, this is just an example to show
the difference.  I hope it accomplishes this goal.

This is based on 360° being equal to the length of the equator, and
for longitudes and latitudes down there it works well enough. But it's
already grossly inaccurate for east-to-west distances not farther
north (or south) than N +/-45°.

Re: [rules-users] @key declarations for a type - What's under the hood?

2014-02-27 Thread Wolfgang Laun 
Works as you'd exprect it - and here we go:

declare Thing
   size : int
end

// A room is also a thing
declare Room extends Thing
name : String @key
end

// A door is a pathway between two rooms
declare Door extends Thing
   fromRoom : Room @key
   toRoom   : Room @key
end

rule "startup"
when
then
   Room kit = new Room("kitchen");
   kit.setSize( 10 );
   insert( kit );
   Room off = new Room("office");
   kit.setSize( 15 );
   insert( off );
   Door kitoff = new Door( kit, off );
   insert( kitoff );
end

Output:

Door( size=0, fromRoom=Room( size=15, name=kitchen ), toRoom=Room(
size=0, name=office ) ) connects Room( size=15, name=kitchen ) and
Room( size=15, name=kitchen )

There are no fancy hidden things in this bean generator, so your Door
would have an empty constructor and a constructor with two Room parameters:

Door door = new Door( fromRoom, toRoom );

Re: [rules-users] VCRP - Distance calculation in getMilliDistance

2014-02-27 Thread Geoffrey De Smet

Hi

I´ve download Optaplanner a couple of months ago and found it 
fantastic!! Congrats to Geoffrey!


I´m not a programmer, but a logistic consultant to a non-governmental 
organization (NGO) of recycling products and like to give my "cent of 
contribuition" if it applies.

Intresting use case :)
I love that fact that NGO's are taking advantage of this software too.

Do note that the examples/docs are aimed at Java programmers (because 
any real-world application requires customization to the actual 
organization that wants to use it), OptaPlanner doesn't try to be a 
generic out-of-the-box VRP solution (but something like that can be 
build downstream upon OptaPlanner).


1. Distance Calculation:

I´ve learned from a person that works with georeference that a good 
aproximation in calculating distances from latitude and longitude is 
to multiply the Euclidean result by "111.1".
This "magic number" will give the approximate distance in kilometers 
and then the final soft score will show the minimum distance in "km" 
and not in "fuel" (although they are related).


=
  public int getMilliDistance(Location location) {
( ... )
  (latitudeDifference * latitudeDifference) + 
(longitudeDifference * longitudeDifference));

  return (int) (distance * 1000.0 * 111.1);
  }
=

2. Heteregenous vehicles

Many times a fleet is made of different vehicles, different sizes, 
capacity and one of the most important,  different mileages (in 
Km/litre or litres/100 km).
How can I put it in vehicle parameters, together with capacity and 
took into account in score calculation?

Doing so, the score would be calculated as minimum(Distance*mileage).

That requires Java programming, but it's not that much work:
- add the fields on the class Vehicle
- add the fields in the xml input
- use the fields in the score DRL


3. Real example
I fed real data into Optaplanner VCRP and plot the results in Googlemaps.
Due to one way streets, the result does not look efficient to the 
drivers of the NGO.
Is there a way to use an internet routing service, like Googlemaps in 
Optaplanner?

If it is possible, can someone help me coding this? :)
Peter Karich was recently planning to combine OptaPlanner with 
Graphhopper (both open source) to accomplish exactly that.
I am not sure if he follows this list, but might be interesting to open 
a conversation with him.

Thank you in advance

Re: [rules-users] @key declarations for a type - What's under the hood?

2014-02-27 Thread Matthew Versaggi 
But what if you now have 2 declare statements in which one defines itself
in terms of the other ...

// A room is also a thing
declare Room extends Thing
name : String @key
end

One would instantiate an object like this:
Room room = new Room("office");


// A door is a pathway between two rooms
declare Door extends Thing
   fromRoom : Room @key
   toRoom   : Room @key
end

How would one instantiate an object of 'Door' ?

[rules-users] Kie-sprind.xsd - Are the configuration options limited compare to drools-spring.xsd?

2014-02-27 Thread mattmadhavan 
Hello,
I am having hard time moving from 5.4 to 6.x due to the Spring
configuration, viz configuraion options fro Custom operators Evaluators,
Custom accumulators etc.

Can some one please let me know?

This is what see for the configuration option for kie-spring.xsd (Drools
6.1)  



/Look how limited this is to when compared to droos-spring-xsd (Drools
5.x)/. Am I missing some thing? Are many of the old configuration options
condensed to  the *work-item-handler* ?

 

Any ideas please?

I appreciate in advance!

Thanks
Matt'M

Re: [rules-users] sliding window question

2014-02-27 Thread Wolfgang Laun 
For an average, the accumulate CE would be best:

accumulate( Reading( $reading: reading ) over window:time( 30s );
$avg: average( $reading ) )

You could add this as the last pattern to the rule where you raise the alarm.

None of this was compiled or tested by me.

Like I am afraid, this is left over document from the old days. You have to

If you are looking for simple rule-flow you can achieve it with Salience.

and I am able to configure it to configure itvia spring Spring as follows.

"inListED"
class="org.facs.ncdb.drools.utils.InListEvaluatorDefinition" */>




<*drools:configuration> 

   

 *



  
I am trying to do the same in Drools 6.x! How do I accomplish this? I cannot
find any documentation.


 
 
 

 
   



*   
   

*   
/>



I need to replace the * *tag  for drools 6.x? 

Any ideas how to configure Drools Custom operator using Spring?

I appreciate in advance!

Thanks
Matt'M

Re: [rules-users] Rule Flow Creation

2014-02-27 Thread mattmadhavan 
HI Ray,
Bear with me, I am kind of new to Drools my self. from What I understand .rf
is old. You have to use the new jBPM to which the Ruleflow id part of. The
rule flow file extension is .bpmn.

Also I am afraid the Eclipse plugin does not do a good job of creating the
good rule flow due to its own limitations. You will have to use a different
IDE for that, like Guvnor or the new 6.x Drools workbench, both of which I
have not used.

Are you sure you are looking at the correct version of the manual? You might
be reading an outdated document. Please read more on jbpm.

Thanks
Matt'M

[rules-users] Rule Flow Creation

2014-02-27 Thread Ray Hooker 
I am trying to create a rule flow.  I have installed the JBoss Drools 6.0 Core  
IDE component installed.  When I try to create a rule flow, it gives the option 
of a “Flow File” but what is created is a .bpmn file, not a .rf file.  Also the 
options are totally different from the screen shots in the Drools reference 
manual.  Any tips are appreciated.

Ray

P.S. - I am also wondering whether Intellij has better support.

Re: [rules-users] sliding window question

2014-02-27 Thread Lin Lin 
Hi Wolfgang，

  Thanks so much!   I will try the sliding window over the time.  I also need 
to give the average reading over the last 30 seconds in the alert message. How 
would I do that?

Thanks
Lin

[rules-users] NullPointerException when calling Scan manually

2014-02-27 Thread Brecht De Rooms 
Dear Drools users,

I just merged all my code to Drools 6.0.1 and I am happy to see that it is  
more stable. Several issues I had with 5.6.x do not present themselves in  
6.0.1. I am still stuck on one bug however that occurs randomly. I wrote a  
unit test in which I deploy new rules and then call scanNow. Often the  
unit test succeeds, but sometimes it throws this nullpointer exception.

[rules-users] StatefulKnowledgeSession

2014-02-27 Thread Raja Sekhar 
Hi,
How do cache the StatefulKnowledgeSession, instead of creating a new
session every time.
Using storm for data extraction and calling the rules to process them
