Hi,
in drools planner I have built an application that has a rule-set with 6
hard-constraint rules and 6 soft-constraint rules. I am optimizing this
rule-set now and then already for a very long time (around 2 years).
Currently I am having difficulty with solving local optima problem

I have been using Drools for several years, but just with constraints
(rules) on 1 set of objects at a time. Think many rules, few facts in a
stateless session. I have been given a new project at the office which
requires having about 10-100k facts and few rules. These 10k facts would be

Hi Geoffrey,
I tried to follow your advice, but by debugging I noticed that he still did not
consider taboo the right moves.
For not implementing the changes to the solver I modified the data object model.
But now I have another problem, I do not understand the log.
Normally when I make a

I have a problem with the list of taboo search. I

For example:

What is the difference between completeMoveTabuSize and partialMoveTabuSize?
By what method compares the current move with moves in the tabu list?

I'm
sorry but I have not had time to find a stable solution for

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,
1) Do you have a StartingSolutionInitializer?
I don't use StartingSolutionInitializer but I generete a XML file with the
initial solution. Is not the best way but it should not affect the running time
of the solver
2) Are you using relativeSelection?
I'm using relativeSelection
*#Vehicle^2 but with
relativeSelection may decrease and I'm using Taboo Search.
I wont to ask you if for your experience the drools-solver can solve a problem
of this dimension.

To use this tag need gonfigure the XML solverConfig file adding the path of Drl

Hi,
I am new to Drools and I am not able to build the documentation from the

Hello Vikrant,
Sometime ago, you replied to my question as given below. I don't get this
statement. For the GUI, you could use XML rather than create your own
language and let drools compile things automatically. .
can you please elaborate?

Thanks again Mark.
If anyone had done this before, Please share your ideas.
If not, drools experts, Please give me some idea how we can do this. Since
I'm new to drools, I'm not sure where to start. I have short deadline.
Thanks in advance.

Hello,
Actually I want to do the same way Sandeep has described.
1. Can someone please post some example to generate the drl from template?
2.This thread is more than a 1 1/2 year old. Does drools have in-built
template concept now instead of using a template langauge such

how can I create rules programmatically and feed into rule engine?

Hi all,
it looks like the only mode supported for rules debugging by the
Eclipse plugin is Drools Application.
If my understanding is correct, are there any plans to support
debugging in situ - i.e. attaching Eclipse to an already running
application (server) - like Java debuggers can?
Thanks

Hi guys,
I have to refresh my application's GUI when a rule has been verified at

RHS part of the rules, but all outputs are given all together at the end of
JBoss Rule Engine execution.
Can you help me in some way?
Thanks
