OK, great I understand :)

What version of Guvnor are you using?

Yes, the starting time of B = Math.max((endTime of task before B), 
(endTime of task A + 7mins)) as long as it is smaller than (endTime of 
task A + 8mins).
Yes, it is pointless to investigate the solutions where task B starts 
8 minutes after task A and the user doing no task that last minute.
The 8 minute is just a constraint that the task in between tasks A and 
B cannot take longer than 7:59s.


I am thinking that maybe instead of using time itself as the planning 
variable, we would use time just to determine the Hard and Soft scores.
So if Task B is scheduled after Task A + 8mins by the solver, then it 
inflicts on the hard score. Similarly if Task B is scheduled before 
Task A + 7 mins.

Does my reasoning make sense in any way?
Yes, but personally, I 'd design it differently (although I have no 
proof that my way would be better), like this:
"Task B is scheduled after Task A + 8mins by the solver" => make this a 
hard constraint
"Task B is scheduled before Task A + 7 mins" => make this a build-in 
hard constraint (= not a constraint in the scoreDRL or ScoreCalculator, 
but by design, see manual).
Each Task is assigned to a previousTaskOrPerson (and this variable is 
chained). It does not know it's startingTime directly.
The scoreDRL or ScoreCalculator calculates the startingTime of a Task 
dynamically, by applying this logic:
  starting time of B = Math.max((endTime of previousTaskOrPerson of B), 
(endTime of task A + 7mins))
Note: "Chained=true" guarantees that there are no cycles of Tasks and 
that no Tasks exists with a previousTaskOrPerson == null.
Note: "(endTime of task A + 7mins)" is not hard coded in the score 
function: you won't find "7" or "A" in there.




thanks,
Josef

Hi Geoffrey,

Well I want to leave 'space' between tasks in the situations
where there are hard constraints that require me to put this space.

This makes the chaining technique harder to model, but I wouldn't
write it off yet.



As a simple example:

Task A: Put pasta in boiling water (duration 40 seconds)
Task B: Take pasta out of boiling water (duration 50 seconds,
cannot start before 7 mins after Task A finishes, cannot start
after 8 mins after Task A finishes)

Does it make sense to wait longer than 7 mins after task A
(presuming no other task forces occupies the user at that time)?
Put differently: Can we say that the starting time of B =
Math.max((endTime of task before B), (endTime of task A + 7 minutes))?
If we can say that, it's pointless to investigate the solutions
where task B starts 8 minutes after task A and the user doing no
task that last minute.
If we can say that, then chaining can calculate the the starting
time of a task on the fly differently.


Task C: Chop vegetables (duration 2 minutes).

This will evidently leave some gaps. The ideal result from the
solver should be:

Task A: at time 0 (ends at 40s)
Task C: at time 41s (ends at 2:41)
Task B: at time 7:40

There is a gap between C and B which is OK.

If another Task is added to the story:
Task D: Prepare sauce (duration 7 minutes)

I would want the following result:

Task A: at time 0 (ends at 40s)
Task D: at time 41s (ends 7:41s)
Task B: at time 8:42s (ends 9:32s)
Task C: at time 9:33s (ends 11:33s)

Task C can actually take place before Task A too.

I still need to read and understand the chaining functionality
properly. Do you think it would allow me to achieve the above?


I don't know.
But using continuous variables in a search problem such as this
that smells discrete with discrete constraints (A must start
before B, ...), could blow up the search space unnecessarily.

If you want to look into using continuous variables: the support
for it is limited currently.
you can reuse the Drools Planner metaheuristic algorithms
(including termination, score, ...), but there's no decent generic
move factory support for continuous variables yet.
So you 'll have to write a custom MoveFactory that creates a
limited subset of moves.
Also, construction heuristics can't handle continuous variables
yet, so you 'll have to write a custom SolutionIntializer.
There are examples with a custom MoveFactory and a custom

Re: [rules-users] How to make available declarative model to all packages.

[rodolphio]

Hi manstis,

I allready have made the 2 steps you mentioned above. This is not the
problem.

The problem is the following step 3:
Going to the "Edit" tab in the package "x.y.z" and adding the types from the
imported declarative model  in the list named "Configuration: Imported
types", because if I click on the green + there is no type from the
declarative model to choose.

And my rule in the package "x.y.z" needs the missing type. So the package
cannot be build.

I hope I have expressed my problem now clear enough.

Thanks in advance.

I'm not sure what exactly causes your errors - is it exactly what you
have posted, or anything different from what you have written, with
that line moved elsewhere or anywhere?

What does the resulting DRL look like?

A semicolon at the end of the statement is indicated unless it's commented out.

[rules-users] fire a rule only once (for the time being)

[slyfox]

It seems like there are many similar problems but I have not been able to
find anything that addresses my issue exactly.  

I have a stock trading application, and I want to check if the price is out
of a range (high,low)

if the price goes below low, the problem is the rule keeps firing if the
price keeps going lower, this creates too much noise and overhead.  

I thought maybe the no-loop and duration attributes would help but they
didnt.  

I know I could check not(Fired()) and use insert fired but I believe that
spans the entire session which I do not want either.  

Is there a way to say fire this rule if true once then wait a period of time
before I check again.

>From what Ive read maybe agenda filters, but I am not sure if that is
flexible enough.

Re: [rules-users] Drools Guvnor 5.2 Issue on Websphere AS 7

[Ravikiran]

Hi,

Drools Guvnor 5.4.0 Final  - I came to know that this version may not work
successfully in Websphere because IBM Websphere uses OpenWebBeans as CDI
implementation. Where as JBoss uses weld and this seems to differ. Not very
sure about the implementation of two sides...is it?

Drools Guvnor 5.2.0 Final - This is deployed successfully deployed on
Websphere, and i got the blank page after the sample repository is created
during launching.

@Guvnor experts, do you suggest any other version of drools guvnor
distribution without weld that can resolve my above issues?

Thanks

Re: [rules-users] Compiled rules differ KnowledgeAgent vs ResourceChangeScanner

[lhorton]

I have found a solution for this problem, but I don't know why the solution
works.  I went through the decision table and modified or deleted each
condition column until I isolated the problem condition.  It's a long story,
but the short version is that the condition did a string comparison using
the == operator, like this:

 job.legalActionType == "$param"

the field legalActionType is defined as a String.  When I changed this
condition to compare using equals():

job.legalActionType.equals("$param")

the problem went away, i.e. the rules fired normally whether loaded by
spring or by resource scanner.

In a nice twist, a few days after fixing this spreadsheet, one of our
business analyst rules writers came to me asking for help troubleshooting a
change he'd made to some rules.  He added some string comparisons but the
rules were not firing as expected.  I had him change the == comparisons to
equals(), and the rules fired normally.

I took this new file and stripped it down to a minimal drl file (3 rules)
and can repro this behavior in a unit test.  I found some other ways to
"fix" the rule, by adding conditions and by removing unused rules. I'm
working on building a set of files that I can load up in a bug report, but
in the meantime if anyone is interested, I'm attaching a short write-up of
the problem and the rule-based solutions.

Again if anyone has suggestions of other things I could look at to help
debug the problem, do let me know.  thanks also to Mark and Wolfgang for
earlier testing & debugging help.

Re: [rules-users] Continuous Planning values for task planning

Yes, the starting time of B = Math.max((endTime of task before B), (endTime
of task A + 7mins)) as long as it is smaller than (endTime of task A +
8mins).
Yes, it is pointless to investigate the solutions where task B starts 8
minutes after task A and the user doing no task that last minute.
The 8 minute is just a constraint that the task in between tasks A and B
cannot take longer than 7:59s.

I am thinking that maybe instead of using time itself as the planning
variable, we would use time just to determine the Hard and Soft scores.
So if Task B is scheduled after Task A + 8mins by the solver, then it
inflicts on the hard score. Similarly if Task B is scheduled before Task A
+ 7 mins.
Does my reasoning make sense in any way?

thanks,
Josef

[rules-users] Moving comment in DSLR file causes issue under 5.3

[drdaveg]

This is an odd one.  I was testing some DSL and have been tracing back an
error in the translation.  The line marked in the code below, even as a
comment, causes multiple "cannot be resolved" errors when moved.  Any
thoughts on what could cause this other than a bug?

Note that almsot all of the code is commented and as it appears now
generates the errors.  If I move the line to the LHS the "cannot be
resolved" errors go away.  The only interesting thing shown in the DRL
viewer is that some of the comments appear duplicated.

[rules-users] Drools/Tomcat/Mysql - dueling repository.xml's

[mfeber]

I am fairly new to Drools.  I am using guvnor 5.4.0. Final installed on
Tomcat 7.0.27.  Following the instructions in the documentation, I 
1) Defined/downloaded the a repository.xml pointing to a mysql instance
using the Administration -> Repository Configuration wizard. 
2) Stopped Tomcat, removed the $CATALINA_HOME/bin/repository.xml and
repository directory
3) Copied the new repository.xml to $CATALINA_HOME/bin
4) Started Tomcat
5) Using guvnor, my assets were created/stored in the mysql db
6) Stopped Tomcat
7) Started Tomcat
8) Guvnor wrote a new repository.xml into $CATALINA_HOME (NOT
$$CATALINA_HOME/bin which still contained the db version created in step 1.)
and had 'forgotten' about the assets created in step 5.
9) Stopped Tomcat
10) Replaced the $CATALINA_HOME/repository.xml with a copy of the
$CATALINA_HOME/bin/repository.xml. 
11) Started Tomcat
12) Guvnor started using the mysql instance again and 'remembered' the
assets from step 5

Now there are two repository.xml files in $CATALINA_HOME and
$CATALINA_HOME/bin.  This should not be necessary re the documentation.

Why did it create a new repository/repository.xml in $CATALINA_HOME after a
Tomcat restart? 
Which repository.xml is it really using now?
How can I convince it to only use one of them?

[Also of note: the workspace.xml files in
$CATALINA_HOME/repository/workspaces/default and
$CATALINA_HOME/bin/repository/workspaces/default are identical after step
11.]

Thanks,
   Mark

Re: [rules-users] How to make available declarative model to all packages.

[Michael Anstis]

TBH, I don't understand what it is you are having problems with: this
thread seems to have gone full-circle.

As Esteban states, to share a model in multiple Guvnor packages you need to:
1) Create a model in the Global Area
2) Create a mode in the individual package (choosing to import from Global
Area)

The model can be either POJO or Declarative (as long as they are consistent
across Global Area and packages).

Regarding your KnowledgeBuilder problem. Do the packages build in Guvnor?

Re: [rules-users] Continuous Planning values for task planning

Hi Geoffrey,

Well I want to leave 'space' between tasks in the situations where 
there are hard constraints that require me to put this space.
This makes the chaining technique harder to model, but I wouldn't write 
it off yet.


As a simple example:

Task A: Put pasta in boiling water (duration 40 seconds)
Task B: Take pasta out of boiling water (duration 50 seconds, cannot 
start before 7 mins after Task A finishes, cannot start after 8 mins 
after Task A finishes)
Does it make sense to wait longer than 7 mins after task A (presuming no 
other task forces occupies the user at that time)?
Put differently: Can we say that the starting time of B = 
Math.max((endTime of task before B), (endTime of task A + 7 minutes))?
If we can say that, it's pointless to investigate the solutions where 
task B starts 8 minutes after task A and the user doing no task that 
last minute.
If we can say that, then chaining can calculate the the starting time of 
a task on the fly differently.

Task C: Chop vegetables (duration 2 minutes).

This will evidently leave some gaps. The ideal result from the solver 
should be:


Task A: at time 0 (ends at 40s)
Task C: at time 41s (ends at 2:41)
Task B: at time 7:40

There is a gap between C and B which is OK.

If another Task is added to the story:
Task D: Prepare sauce (duration 7 minutes)

I would want the following result:

Task A: at time 0 (ends at 40s)
Task D: at time 41s (ends 7:41s)
Task B: at time 8:42s (ends 9:32s)
Task C: at time 9:33s (ends 11:33s)

Task C can actually take place before Task A too.

I still need to read and understand the chaining functionality 
properly. Do you think it would allow me to achieve the above?



I don't know.
But using continuous variables in a search problem such as this that 
smells discrete with discrete constraints (A must start before B, ...), 
could blow up the search space unnecessarily.


If you want to look into using continuous variables: the support for it 
is limited currently.
you can reuse the Drools Planner metaheuristic algorithms (including 
termination, score, ...), but there's no decent generic move factory 
support for continuous variables yet.
So you 'll have to write a custom MoveFactory that creates a limited 
subset of moves.
Also, construction heuristics can't handle continuous variables yet, so 
you 'll have to write a custom SolutionIntializer.
There are examples with a custom MoveFactory and a custom 
SolutionIntializer where you can copy paste from, but none with 
continuous variables at the moment.

Josef

Re: [rules-users] Slow compilation (4h) for a single rule

[Edson Tirelli]

   You are trying to avoid the issue. As reported by others, your
conditions should be inside the patterns, not in "or'd" evals in the end,
and yes, it is possible to generate rules like that in an automated program.

   Now, the reason it is taking so long is because of the "or"s. I don't
think there is any bug there. Just for you to understand, an OR is just
syntax sugar for multiple rules. So if you have a rule that says:

A() or B()

   The engine is actually creating 2 rules:

rule 1 when
   A()
...

rule 2 when
   B()
...

I.e., it generates all possible combinations of rules, one for each of
your logical branches.

Now, I quickly counted 26 "or"s in your rule. It is quite possible that
the engine is generating all possible combinations of rules for all your
ORs, and that is roughly (there are some factors that influence the number
of rules): 2^26 == 67108864 rules. To compile 67 million rules, it can
indeed take some time.

I don't know for sure if that is the case without looking at your
application, but to solve your problem you should fix your rule generation,
not look for a problem elsewhere.

Re: [rules-users] How to make available declarative model to all packages.

[rodolphio]

I have made following:

In Guvnor you have to create a Model also in your specific packages and
select "import from global area". Then you have to go to the configuration
of the package and add the classes you want to use in your package.

My problem is that i can't add the classes I want to use in my package.

And than I tried to resolve the problem by deleting the imported declarative
model from the package and deleting the declarative model, I can't create a
declarative model in global area without creating automatically the same
declarative model in the package I want to import it.


Any advices? Thanks a lot

Yes, to get the compiled package, compiled inside Guvnor , but this is the 
problem here. 

The compiled package is a serialized kPackage object . When you get this from 
guvnor, and put it inside your kBase, the object is simply deserialized. The 
ObjectTypeConf conf .getTypeDeclaration() will look in the kBase, and for 
guvnor compiled package this method returns null (don't know why). I think you 
may have a difference between your Guvnor version and the drools runtime 
version. 


You can either use the source got from guvnor ( 
http://localhost:8080/guvnor/rest/packages/org.dfms.model/source ) to build 
your kBase, and this should work fine.

I've looked at the byte code, and there are a couple of methods
starting at line 48: insert( Object ) and getFactHandle( Object ).
Probably due to some optimisation resulting from the peculiar
parameter passing from one call to the only method call inside the
originally called method.

Still, very confusing,...

So, the NPE is not due to some confusion with the object code.

I have noticed that there are other threads running where differences
between executions from Guvnor and local deployments are reported.

This line, in 5.3 code, is the class declaration. Indeed, node an executable

I've found another thread :

I understand that the rule looks pointless and under-optimized, but it's the
only way I could represent this kind of rule in an automated way (I didn't

Sure it's possible that there is a bug. But it's hidden deep. Could be

Re: [rules-users] java.lang.NullPointerException at org.drools.reteoo.ReteooFactHandleFactory.newFactHandle(ReteooFactHandleFactory.java:56)

[Vincent LEGENDRE]

I guess that entryPoints is a map that you build at init. 
Are you sure that the entry points in it are in sync with the actual session ? 
Why not using kSession.getWorkingMemoryEntryPoint(name).insert(...) directly ? 

@Wolfgang : Why can't there be a bug in NamedEntryPoint.insert(...) ? Having a 
NPE here is problematic, especially for a internal variable got from inside the 
same internal method. May be this is not called a bug, but at least the 
exception should be more explicative.. 

Best guess for now is that the problem is inside your code (dont know where) 
and not inside drools code. The NPE, even if it should have been more user 
friendly, is certainly just a consequence of a bad usage somewhere. If it works 
well using DRL, and not using Guvnor, it may be a good track to follow. If you 
have the same usage (session creation, inserts, fire ...), then you have 
differences between the two ruleset (rules and/or model is different). With 
Guvnor, you can also download the "source" (just like a big DRL) instead of the 
pkg. This can be a solution too.

No surprise: If the entryPoint were null, you'd have a NPE right
there, and not in NamedEntryPoint. If obs were null, nothing at all
would happen.

I'm investigating a little.

Re: [rules-users] Using Global Model for all packages

[Michael Anstis]

Sounds like there's a problem :(

Could somebody please raise a JIRA (for  Guvnor) and provide full details
of exactly what the problem is (including a repository export, if possible).

With kind regards,

Mike

Re: [rules-users] Using Global Model for all packages

[Vincent LEGENDRE]

Never managed to get that working properly too ... 

3 options : 
- Try again to really share the model from global area to all package. 
- Put the jars in Guvnor classpath (or tomcat classpath) 
- Write a REST client that upload the jar to all packages.

Hi Admins, 

I have been using GUVNOR 5.2 from sometime now. We have different packages 
created, as per the requirement of different teams. However, they do use the 
same MODEL. I was wondering if we could simply upload a jar in the global 
area, and use the same in every other package. I know that we can create 
models for each package and say Import asset from global area. However doing 
the same again and again, isnt helping me in any manner. 

The rules arent getting updated with the class files and the rules 
validation failes with in the Business Rule Assets. 

Is it that this doesnt work or is it that am missing on something??? 

Kindly assist ASAP.

Re: [rules-users] Slow compilation (4h) for a single rule

[FrankVhh]

Hi,

There is something that I must ask... Why do you evaluate perfectly simple
patterns in an eval, I wonder?

rule "CONFIG_1-3UCO07"
salience -90
when
Number(rel_4226982244: intValue < 1 )
Number(rel_7521194: intValue < 1 )
Number(rel_787633980: intValue < 1 )
Number(qty_1331544548: intValue != 1 )
Number(rel_1425187049: intValue != 1 )
Number(rel_1180441096: intValue != 1 )
Number(rel_3132221704: intValue != 1 )
Number(rel_1663554156: intValue != 1 )
Number(rel_1940612775: intValue != 1 )
Number(rel_1735126416: intValue != 1 )
Number(rel_3962361266: intValue != 1 )
Number(rel_882187: intValue != 1 )
Number(rel_1169008280: intValue != 1 )
Number(rel_3495503197: intValue != 1 )
Number(rel_70290066: intValue != 1 )
Number(rel_1333860961: intValue != 1 )
Number(rel_2793542368: intValue != 1 )
Number(rel_952404632: intValue != 1 )
Number(rel_2712335119: intValue != 1 )
Number(qty_4276673135: intValue != 1 )
Number(qty_3950051097: intValue != 1 )
Number(rel_3391032645: intValue != 1 )
Number(rel_2738029181: intValue != 1 )
Number(qty_4125201080: intValue != 1 )
Number(rel_663254919: intValue != 1 )
Number(rel_3059142355: intValue != 1 )
then
vh.error(kcontext, "Error ...");
end 

Of course, this is still nonsense as long as you do not have a way to
constrain the number that you evaluate. The rule, as written above, will
fire from the moment you have one single number that has an intValue below
1.

Regards,
Frank

Re: [rules-users] Slow compilation (4h) for a single rule

[Wolfgang Laun]

There are 26 patterns Number(). Now I don't know how many facts of
that type you have, but this sequence will produce all combinations of
all available facts. (This is the worst example of this anti-pattern
I've seen.)

The or-ed evals will try to create parallel nodes in the network, and
the not should guarantee that none of those exists.

I'm not sure what the rule should actually ascertain. Could you
provide a simple example, using 3 numbers, describing verbally or by a
regular boolean expression when the rule should fire?

E.g. "it should fire if there is one Number != 1, another Number < 1
and a third Number != 1"

There is a point, because the rule I've posted compiles and causes the same
problem, I've just removed redundant code to expose the problematic section.

Well, I do mind the "nonsense Number()". There's no point in

[rules-users] Slow compilation (4h) for a single rule

[fx242]

Hi,

Recently I was trying to optimize the rule compilation time for my KB (~4K
rules).
I do a full KB compilation every night, as most of the rules are dynamic
generated/converted and managed by the business operators.
The compile time was not very good (around 3 hours on a 8 core Xeon CPU),
but is was acceptable.
On the other night I was alarmed that the compile time was doubled overnight
without an obvious explanation or any relevant rule count increase. After
some debuging I've traced the problem and was shocked to find that most of
the rules KB (4K rules) compile under 5 minutes, except one. This single
rule was taking all the 4h to compile!
I'm using DROOLS 5.2 Final.
The rule example below samples the problem (don't mind the nonsense Number()
conditions):

I've noticed that the last "not(...)" is the problematic condition. Is there
a limit using eval() and or-clauses, or a known problem?

Well, then it's a bug in your code. Do we all agree on this now?

org.tass.utils.ExpertSystemManager.java is our class and the source code is
this:

153. *public* *void* insertObservation(String entryPoint,
Observation obs) {


154. *try* {

155. *if*(entryPoints.containsKey(entryPoint)) {

156. entryPoints.get(entryPoint).insert(obs);

157.

158. ksession.fireAllRules();

159. }

160. }

161. *catch* (Exception e) {

162. logger.error(e, e);

163. }

164. }

>>Where is org.tass.utils coming from?

Where is org.tass.utils coming from? it is our class.


>>It's still a mystery to me how it's possible to have a stack trace

I agree, at the line 48 there isn't code. It would seem that "Drools 5.3.0
final" has different binary and  source code.


>>There is another mystery : why this is working when getting rules from a
DRL file and not from Guvnor ...

Yes, I did.

The package compilation is ok.


>>What is sure is that the problem does not comes from the rules, as the
stack trace shows an "insert" call outside the rules, otherwise there would
be a >>reteoo...ConsequenceInvocator (something like that) before ..


yes, It is sure


>>And a last question : is "org.tass.utils.ExpertSystemManager" a class

org.tass.utils.ExpertSystemManager.java is our class. We aren't using
third-party
framework.


Thank you
