I 'd like to get the number of queens which have the same y.
I used to do this with a query:
query "multipleQueensHorizontal"
Queen($id : id, $y : y);
Queen(id > $id, y == $y);
end
And then ask the size() of it.
But now I should be able to do this with the accumulate function:
$multipleQueensHorizontal : Integer()
from accumulate(
$q1 : Queen($id : id, $y : y);
Queen(id > $id, y == $y);
, count($q1)
);
However, I get a parsing error on it:
Caused by: org.drools.rule.InvalidRulePackage: [31,37]: unknown:31:37
Unexpected token ';'[33,6]: unknown:33:6 mismatched token:
[@123,814:814=',',<12>,33:6]; expecting type THEN
Apparently the ; in of "$q1 : Queen($id : id, $y : y);" is inacceptable?

'accumulate' currently can only take a single Pattern, multiple
correlated Patterns is scheduled for a future release (hopefully next
one). Also don't use semi colons they just aren't needed and in some
places break things.

As a workaround I replaced my query with a rule which does a logical
assert of a new WorkaroundMultiplePatternAccumulate object.
Then I do an accumulate of counting those.
Because it's dirty code atm (doing some class casting, still using the
double sum() function, ...),
I expected a noticable performance decrease for TTP.
To my surprise it was a performance increase of about 1%?!?
Can't wait to see MultiplePatternAccumulate implemented :)
Is there a jira issue to watch?
I 'll make a patch for sumInteger() tommorrow.

Geoffrey,
I don't think you need multiple patterns for this specific use case:
rule "multipleQueensHorizontal"
when
Queen($id : id, $y : y)
Number( $multipleQueensHorizontal : intValue )
from accumulate( $q : Queen(id > $id, y == $y), count($q) );
then
// do something
end
Am I misunderstanding your use case?

This would result in the number of (higher id) queens which are at the
same horizontal position for a certain queen.
But I need the sum of that for all queens.
For example for these rows:
AB_D_F
__C___
____E_
This would give me:
A: 3
B: 2
C: 0
D: 1
E: 0
F: 0
That's all correct, but I need the sum of that:
multipleQueensHorizontal: 6
After that I 'd like to use that for a sum of multipleQueensHorizontal,
multipleQueensDiagonalUp and multipleQueensDiagonalDown (vertical is
always 0 due to my moves and start position) which gives me the score
(the only thing that I really need).
I could of course do a logicalAssert of a number per queen and then
accumulate those, kinda what I did with the
WorkaroundMultiplePatternAccumulate object.
But it looks like accumulate is improving my performance already, great
work :) Or could it be because I am now using rules with assertLogical()
instead of query's?
Am I misunderstanding your use case?
