If you have enough memory, you can cache the distance from every
location to every other location
before Solver.solve() or in Solution.getProblemFacts().
The machineReassignment example has a similar big 2 dimensional grid for
the cost of every machine to every other machine.
Don't go blindly
Hi Mark,
Thanks for getting back to me about this.
Actually, when I mentioned that I was making the project public a bit
prematurely, the source of the knowledge base was one of the main reasons. At
the moment the rules are hard-coded in that class path location for a couple of
reasons.
Hi,
I am using the following rule
package com.demo;
import com.sample.model.Product;
import com.sample.model.Products;
import java.util.List;
import java.util.Set;
dialect mvel
rule Product_0
no-loop
when
Product(id: hlId) accumulate (e :Product(hlId == id), $sum1 : sum(e.t1) )
then
Raja,
it is not clear what you are trying to achieve.
The rule might be well written or not, we don't know your requirements.
If id is what it should be - an identifier - your accumulate constraint
would match a single object for each Product (the original product itself),
which looks suspicious.
Hi Davide,
I am trying to group by Hild. Here first i will get the hlld into id and
segregate the results by hild and sum the value t1
If you take an sql
select sum(t1),hlid from product group by hild
so i will get
if the data is
hlid t1
110
110
2 10
2 10
the result would be
hiid t1

Dear,
thanks for the quick response, I lost track of this entry due to some
deadlines. I was planning to compile a package with all the necessary code
but as mentioned, the issue only shows up periodically and currently I can
not reproduce it anymore. A while back I wrote a hack that simply
Hello,
I have a long drl file that was generated from a custom rule engine(due to
historica reasons).
I have a long list of rules - in certain order .
I imported the drl file from the Gunnor GUI. I did a Create New from the
knowledge Base view and chose the import drl file option.
My problem is
You might be able to hack the import mechanism. (Rearranging according
to sorted rule names is a poor option anyway.)
But the quickest solution is, I think, to prefix each rule name in the
original DRL with a generic key, e.g. 000 to 999 or similar, and
to import again. Probably doesn't take more
Humm,
Is there any other Cleaner way please?

Dear Drools Users,
When you create you own KieBase you can set the KieBase to streaming
as follows:
KieBaseConfiguration config =
KieServices.Factory.get().newKieBaseConfiguration();
config.setOption( EventProcessingOption.STREAM );

Hi, I'm new to OptaPlanner, and reading through the planning examples in the

involves a variable number of planning entities, which I didn't really see
addressed by any of the examples; they all seemed to me more focused on

Hi Ge0ffrey, thanks for your quick reply.
Actually I'm quite sure it's my code, I just used brute force to enable
completeness on my small problem. I've attached my problem this time just

If you run my code you will see that the solver hits a 0hard/0soft score

We do need to make it easier to unit test things. One idea is to allow
annotations in a unit test to declare the subset of rules in scope for testing.
The annotation could specify a package, a rule or even 1..n qualifiers. If
rules have qualifier annotations on them, they would be sucked in.
