Re: [rules-users] Non short circuit ANDing

Ø I can't think of a way to accomplish this without severely impacting performance as I think you'd essentially end up evaluating all of your rules with a secondary algorithm Agreed. Such a "when do rules fail to fire?" accounting capability should not be a burden to the Drools runtime. But what about a .DRL "enrichment " tool that generates explicit accounting .DRL code? Leaving the run-time unburdened, but liberating the .DRL author from all the key-stroke labor? Ø However, I only claim to know that I know very little, so grain of salt I don't even claim to know very little! (But do claim to be excited to "do the work" necessary to learn).

If you dig deeper into the Rete algorithm and examine how it works, you'll find that the node relations and redundancy elimination greatly abstracts away from what we think of as the LHS of a rule. In the node network, it's no longer a set of conditions grouped together for each rule that are checked for true/false collectively. I can't think of a way to accomplish this without severely impacting performance as I think you'd essentially end up evaluating all of your rules with a secondary algorithm.

I mean, yes, what you suggest here works (and it works perfectly). But, for such an important and common user concern, we currently face a lot of "Drools .DRL keystroke labor" to get us completely where we need to be wrt to coding this tactic completely. Does your Intellifest white paper (today is the day? HOORAY!) comment at all on strategies to achieve this pattern in .DRL code? It would be way cool if the framework itself liberated us with a "just add water and out comes the .DRL code you want" capability. Such a capability would deliver to users a full answer wrt to our "when do rules fail to fire?" accounting needs. Admittedly, I don't know of a best way to proceed wrt to potentially providing that capability. But I do know it would be nice. As always, thank you very much for this forum's superb support. -----Original Message----- From: rules-users-bounces@lists.jboss.org<mailto:rules-users-bounces@lists.jboss.org> [mailto:rules-users-bounces@lists.jboss.org<mailto:rules-users-bounces@lists.jboss.org>] On Behalf Of Wolfgang Laun Sent: Tuesday, January 29, 2013 2:07 PM To: Rules Users List Subject: Re: [rules-users] Non short circuit ANDing [Groundhog Day] If you need to know all the reasons why a rule doesn't fire you'll have to evaluate all relevant conditions individually and keep track of the positives.
