[jboss-jira] [JBoss JIRA] Commented: (JBRULES-1040) Multi-pattern accumulate support
[ http://jira.jboss.com/jira/browse/JBRULES-1040?page=comments#action_12378192 ]
Geoffrey De Smet commented on JBRULES-1040:
-------------------------------------------
It works :) I was apparently still testing with 4.0.1.SNAPSHOT instead of
4.0.2.SNAPSHOT... rookie mistake.
Though the test times prove that backwards chaining behavior is hurting the local search
solver at the moment:
before: with the logically asserted workaround object
after: with the multipattern accumulate

after: INFO Solved in 71 steps and 1516 time millis spend.
nqueens16:
before: INFO Solved in 31 steps and 1453 time millis spend.
after: INFO Solved in 31 steps and 7625 time millis spend.
nqueens32:
before: INFO Solved in 55 steps and 11781 time millis spend.
after: didn't want to wait but the first 3 steps took around 40 seconds.
Great work for getting it fixed, but obviously I can't wait till query's can be
configured to work forward chained :)

[Edson said there might be already such an issue, but I couldn't find it looking
through jira.]
Something like this should be possible:
$multipleQueensHorizontal : Long()
from accumulate(
$q1 : Queen($id : id, $y : y);
Queen(id > $id, y == $y);
, count($q1)
);
