Hi to all,
I have a bug in my code that eludes me. I have defined paths and a list to
hold them:
(deftemplate path
(slot name)
(slot cost))
(deftemplate path-list
(multislot list))
Then I tried to set a rule that would add any paths (actually their fact#) to
the list if they were not there already:
(defrule add-path-to-list
?path <- (path)
?pathlist <- (path-list(list $?list))
(not(member$ ?path $?list))
=>
(modify ?pathlist (list (create$ $?list ?path))))
This adds paths to the list, but will continue to add them even though they
are in the list. Any Assistance would be greatly appreciated.
