Hi. I'm trying to figure out how to express a Condition that does the

As an alternative that avoids the unnecessary counting of FeV1,
consider adding a helper fact type and a couple of (DRL) rules.
declare Existence
value: boolean
end
rule not2exists
when
exists FeV1()
$e: Existence( value == false )
then
modify( $e ){ setValue( true ) }

Good point Wolfgang,
If the use case allows (or even demands) for discretizing the locations
and putting in on a grid, that should definitely be done.
For example, putting cargo on an airplane is also a bin packing problem,
but because the cargo items need to be attached to the airplane,
so
Hi Geoffrey, Wolfgang,
sure is the problem discretized (the layer on which it should be packed is
fixed size say 100cm x100cm and the rectangles have sizes to the cm) , that
was not the question.
I can build a planning value x/y with a list of 100 entries for every cm and
combine them, but i

Should I repeat what Geoffrey told you in your previous thread ?
Will you try again and again to post your project, hoping we will do your work
for you ?
I gave you the main ideas, first work with that, and come back with precise

I'm experimenting with Drools and have troubles understanding the way

if the way the accumulators work is designed as described below or of it has
something to do with my rules configuration.

Hi Wolfgang,
thanks for the swift reply. Probalby you are right about the fact that a new
context is created instead of a new accumulator. But why is it looping over
all the context that are created for that accumulator?
Surely the output attached to the first thread is not what you would

Think logically.
Yes, you're right: it's because of performance reasons during incremental
score calculation.
If a CloudComputer changes during planning too, it should be set as dirty in
Drools by Planner calling (workingMemory.modify(computer)). If the whole
computer is made dirty, that has a serious effect on

I save many different knowledge packages for different accounts to a
database. Most accounts use a particular service to pull data from the
database but not all of them. Because of this I wanted to set this service
as a global on the session.
However, because not all accounts use the service I
I am not sure to have fully understood you last requirement, nor if you set the
global inside or outside the rules.
Anyway, I see these options :
- declare your globals for all packages, but it seems that this is not what
you want
- enclose the global setting in a try...catch and just
Either your second or third option sounds like what I want to do.
Sorry for the confusing last requirement. I was trying to say that I want
to use spring to inject all globals and then set them on the session without
explicitly having to look them up inside each rule. If I wanted to go this

Drools says property accessors must not change the state of the object so I'm
guessing your second example is not the correct way to do it in either
drools version.
Out of curiosity do things work right if you remove the ruleflow-group on
your first rule in Drools 5.3?

Your first rule did not fire for me as expected using drools 5.3. Please ignore
