Re: [rules-users] Drools Fusion: updating event duration
A couple comments: * The temporal reasoning features/operators are available in both CLOUD and STREAM mode. The biggest differences are that in CLOUD mode there is no automatic garbage collection of old events and you can't use sliding windows, but everything else works. * You can insert events with old timestamps, but in that case it is the rule's author responsibility to understand that sliding windows using that event type might be affected and if running in STREAM mode, you should define an expiration policy for that event type that will keep him in memory for enough time to match any rules that require it. For instance, if in your application events will have a maximum duration of 24hs and because of that they can be inserted into the system with a delay of 24hs, you should define an expiration policy for it that is at least 24hs.

[rules-users] Drools Planner: Vehicle routing problems
Hi, as discussed the other day with Ge0ffrey on IRC, I've been trying to get some vehicle routing done using the new TSP / chaining functionality in drools planner. I've written an example, but am having problems with the chaining of jobs together. After pulling my hair out, I've put together an example into my fork of planner, showing a simplified example of how I am approaching it, and the problem that can be replicated. https://github.com/davidglassborow/drools-planner/tree/vehicle_routing It is a very simple console app along the same lines as the hello world example for NQueens. On running it will print out the chains, and you will see the some Jobs appear more than once in the same list. On the planning variable it seems to be get assigned in front of itself, I've put some notes in the source, and checked that the same doesn't occur in your TSP example. I'm not sure if its a bug in the way I've setup things, or whether its an issue in the chain move code. Greatly appreciated if anybody in the know gets a chance to have a look.

Yes.

Re: [rules-users] (no subject)
If you look at the implementation of EventFactHandle.getEndTimestamp (not ...eSt...) you'll see why: it returns startTimestamp + duration. You should *not* use methods that aren't in the stable part of the Drools API. Also, the documentation does not tell you that you can map event attributes to start and end of an event - only the start and the duration. -W On 24/02/2012, youssef azbakh azbak...@gmail.com wrote: Hello every body !

Hi , First of all thank you very much for responding me, Yes you're rights getEndTimestamp() == getStartTimestamp()+duration. I thought that the when we give the attribute to timestamp, tha value of the attribute will be token from the session clock. BUT the real senario is that the StartTimestamp() retourne the value given throught the attribute, that is like we specify the moment when the event will occur.

1) No you don't have to save it; just use one of the overloaded methods on KnowledgeBuilder that takes a StringReader, or String or something else similar. 2) I understand there to be one for Drools Expert too, which I'd expect to be in one of the drools-xxx JARs however am having trouble finding it!

Continuing with Michaels' explanation: once the process editor is open you have to search for a button in the toolbar of the editor that will allow you to import a process providing a a file or simply the content.

Re: [rules-users] How to create a drl file or decision table dynamically?
The reason it is not in the manual yet is because it was not promoted to the public API yet. Nevertheless, you can use it, but be aware that there might still be changes on it from version to version until it is promoted to the public API. I am hoping Mark will give me the go ahead to make it public soon. Examples are here: https://github.com/droolsjbpm/drools/blob/master/drools-compiler/src/test/java/org/drools/lang/api/DescrBuilderTest.java The javadoc is not complete, but what is there is correct. Classes are: https://github.com/droolsjbpm/drools/tree/master/drools-compiler/src/main/java/org/drools/lang/api The API is completely typesafe, so you can trust the code completion of you java editor... :) Edson 2012/2/24 Michael Anstis michael.ans...@gmail.com 1) No you don't have to save it; just use one of the overloaded methods on KnowledgeBuilder that takes a StringReader, or String or something else similar. 2) I understand there to be one for Drools Expert too, which I'd expect to be in one of the drools-xxx JARs however am having trouble finding it!

Re: [rules-users] How to create a drl file or decision table dynamically?
There is one (1) sentence and a dozen (12) lines of example in the section about What is New and Noteworhty in Drools 5.2.0 in the Introduction manual. Given that this nano-documentation doesn't tell you what to do with the resulting PackageDescr and that this fluent API is part of the unstable API, I'd put my money on StringBuilder and create rules as DRL text. YMMV. -W On 24/02/2012, Leonardo Gomes leonardo.f.go...@gmail.com wrote: Hi Michael, Do you have a link to the Fluent API documentation? I wanted to answer to this question and couldn't find the link anywhere. Thanks, Leo. 2012/2/24 Michael Anstis michael.ans...@gmail.com Yes. If the data defines the rules then there are numerous options:- - Construct a DRL String yourself and pass this to a KnowledgeBuilder - Use the fluent API to build rules programmatically - Construct an XLS decision table using your favourite XLS (Java) API and look at drools-decisiontables - Construct a Guvnor decision table using classes in droolsjbpm-ide-common (bundled with Guvnor) If the data is to be plugged into place-holders in statically defined rules:- - Look at the use of Drools Expert Templates Decision tables do not lend themselves well to OR as there is an implicit AND between columns. There might be other solutions, these are those that came readily to mind.

[rules-users] Removing many facts have invalid timestamp
Trying to figure out if it can be done in a rule almost some sort of pre
rule before other rules are triggered.
The current rule I have is
rule RemoveInvalidEndTimestamps
salience 100
when
$factN : Fact()
$factsToRemove : ArrayList(size=5)
from collect( Fact(endTime==$factN.endTime))
then
List newFactsToRemove = new ArrayList();
newFactsToRemove.addAll($factsToRemove);
for(Fact n : newFactsToRemove ){
retract(n);
}
end
I am using a cloud based process . I could sort the facts and stream them
in.
Just in a few test cases there are many facts with invalid times , which
kills the speed .
From the log I think that each collection of size=5 , is triggered which
means triggered for 5,6,7, etc.
Just wondering if there is way to say before doing any other rules collect
up all these invalid times and remove them.
I was just going to write up a some java code and filter before feeding
facts into drools but I find the rule syntax is much easier to read for the
non software developers in my group.

Re: [rules-users] Removing many facts have invalid timestamp
Would you please define unambiguously what constitutes an invalid time?
From your code it would appear that one time has to occur fivefold or
more often to
be invalid.
In case any duplicates should be removed a simple high-priority rule
is sufficient:
rule killDuplicate
salience 1000
when
$f1: Fact()
$f2 :Fact( endTime == $f1.endTime )
then
retract( $f2 );
end
