I'd like to use a rule of the following form:
(defrule rule557
(logical
(is-active (name "Some name"))
(in-coverage (tid ?tid) (cid ?cid) (distance ?distance&:(> 2
(count-query-results in-coverage-nearer-query ?tid ?distance))))
)
=>
(assert (tracking-actual (tid ?tid) (cid ?cid)))
)
The idea here is to limit the number of 'tracking-actual' facts w.r.t.
to the number of 'in-coverage' facts. It doesn't work, since I still
get a 'tracking-actual' fact for every 'in-coverage' fact.
The following modification works slightly better, but then I loose the
logical support, which I really need:
(defrule rule558
(logical
(sensor-doctrine-active (name "Some name"))
(in-coverage (tid ?tid) (cid ?cid) (distance ?distance))
)
(test (> 2 (count-query-results in-coverage-nearer-query ?tid ?distance)))
=>
(assert (tracking-actual (tid ?tid) (cid ?cid)))
)
Any suggestions, ideas, anyone?
