Hi All,
I am using drools API, and developed a webservice out of it.
I created rule binary package using BRMS Guvnor.
I used RuleAgent to acces the properties file.
ie RuleAgent agent = RuleAgent.newRuleAgent(/application.properties);
application.properties file was stored in current working
Hello Shekhar,
1) You need to read http://www.jboss.org/drools/lists.html (the list of
todos) if you expect folks to help you. You have replied to a totally
different thread!!
2) You don't need to create a webservice out of the Drools API. There is
already one, called drools-server. Read
Hi all,
In the Drools Solver documentation there is a point that say we can add
multiples entries ScoreDrl. But when I try do that, Drools Solver uses
just one entry to calculate the score, and I need put 2 files in the input.
Anybody could help me, please?
Thank you
That should work.
Check your getFacts() method.
If you can reproduce on trunk (and prove it by putting an error in the
DRL which isn't loaded), feel free to open an issue.
With kind regards,

Hi all,
is possible in a DRL file, useded for droos-solver, recover the score of last
step?
I need it because with the rule I calculate a function score f(n); to
diverrsificate the research if f(n) is bigger then f(n) of last step then add a
penality...

Hi Geoffrey,
I'll check that out today for you and let you know what I find out
with my case. I'm using the following solver dependency:

Hi Geoffrey,
My bad; when I migrated to the new Score implementation I failed to
update my code to properly clone scores in my cloneSolution()
implementation. Thanks for letting me know where to look!
best wishes,

Hi Andrew,
I can't reproduce your problem.
The BestSolution is not null although the best score is.
The LocalSearchSolverScope cannot have a best solution and not a best score.
Could you debug to see where LocalSearchSolverScope.setBestSolution() is
called and why
By the way, if you turn on info logging,
it logs each time a new best solution is found.
If you see a null in there, that's the problem.
However, that logging guarantee doesn't apply if you hooked in a custom
BestSolutionRecaller etc
With kind regards,

Hi,
Here is my test :
I have an appointment to schedule on a customer availability.
I have a list of customer availabilities.
A customer availability is a period.
An appointment needs an exact number of persons.
A resource is composed of persons ( between 1 and n ) and has availabilities
too.
Hey , i would like to use drools solver for a 2d knapsack problem.
Has anyone expirience with that ?
Is drools solver made for such a task ?

I've researched this, a long time ago (trying to find a solution for a
problem from the worse class). Even then, several results could be found
in the literature for the cutting sheet problem for rectangles, showing
that certain parameters (w.r.t. to rectangle dimensions being multiples of

I think it´s more a knapsack problem. And the rectangles have to follow some
business rules,
so that´s the reason try to using solver. Here´s an image of the problem.

That's indeed more like a problem for using rules (and far from the plain
cutting sheet I had in mind), From the examples, itc2007 and
lessonsschedule might give you an idea how to approach your problem.

Just a heads up: drools-solver (not drools itself) will have a couple of
backwards incompatible changes in 5.0.1, but they are easy to fix with

I'm just starting to use the solver as well on a project. Have you

you could use a solution taboo, on all solutions found so far and let the

the problem is that you never know when to stop this algorithm.
that is, when you found the last valid solution.

the new version of the drools-solver supports multiple move factories.

Geoffrey,
In a bizarre co-incidence I had just finished reading the Drools solver
docs. It's very good - it's taken one of the ideas that I'd been mulling
over and implemented it a (good) way that makes me realise I'm hardly out of
Kindergarten with this stuff :-)
