I confirmed my understanding of "casual" by looking it up.

Gosh, does the author of these lines really think that an GP mulls over your body's chemistry before he or she prescribes something against your headache? > > /"One type of shallow knowledge is *heuristic knowledge*."/ Agreed, according to the definition of "shallow". That's not saying that this is an entirely bad thing. > > Should I use drools planning instead just drools expert? I know that drools > planning use heuristic to score the planning problem. I'm not sure I understand your line of thought. "Planning" is a OR discipline, but certainly not necessarily a way to solve a problem such as prescribing medicaments. -W > > Daniel Souza > > -- > View this message in context: > http://drools.46999.n3.nabble.com/How-to-write-a-Heuristic-Knowledge-in-Drools-Expert-tp4018012.html > Sent from the Drools: User forum mailing list archive at Nabble.com. > _______________________________________________ > rules-users mailing list > [email protected] > https://lists.jboss.org/mailman/listinfo/rules-users > _______________________________________________ rules-users mailing list [email protected] https://lists.jboss.org/mailman/listinfo/rules-users
