Hi Geoffrey,
I have modified the LocalSearchSolverConfig class to accept the <scoreDsl> tag.
To
use this tag need gonfigure the XML solverConfig file adding the path
of Drl file and Dsl file associated in two line consecutive in the
configuration file. This code is not the best but is a start....
I send you the code if it can be useful.
I
would also ask when it launches the new version of the solver, and if
this will also include other local search algorithms than Tabu Search
with kind regards,
Marco

New subject: Drools solver info => provide DSL instead of DRL to Drools Solver
dmzpippo-drools(a)yahoo.it schreef:
Hi Geoffrey,
I have modified the LocalSearchSolverConfig class to accept the
<scoreDsl> tag.
Thanks for the patch!
If you want credit, state your full name, and I 'll add an @author tag
in the javadoc.
To use this tag need gonfigure the XML solverConfig file adding the
path
of Drl file and Dsl file associated in two line consecutive in the
configuration file. This code is not the best but is a start....
It seems a bit wierd to me add both the drl and the dsl in the
<scoreDsl>, so like this:
<scoreDsl>/org/.../file1.drl</scoreDsl>
<scoreDsl>/org/.../file2.dsl</scoreDsl>
I am going experiment with this instead, and use it in one the examples,
before I commit the changes.
<scoreDrl>/org/.../file1.drl</scoreDrl>
<scoreDsl>/org/.../file2.dsl</scoreDsl>
Just "watch" this issue to get notified when it's committed on trunk:
https://jira.jboss.org/jira/browse/JBRULES-2333
I send you the code if it can be useful.
I would also ask when it launches the new version of the solver, and if
this will also include other local search algorithms than Tabu Search
Simulated annealing and great deluge are available, but they aren't
production-ready.
Take a look at SimulatedAnnealingAccepter and GreatDelugeAccepter.
I've also written a testcase for both.
Patches welcome :)
I am focusing on conflict based statistics and
multi-threading/clustering first.
PS: If a patch is more then one file, do use "create patch" in your
Eclipse/IntelliJ or "svn diff > jiraNumber.patch".
Also, attach it to the jira issue pls.
with kind regards,
Marco
