[rules-users] Negating a constraint group?
I want to write a rule that says "Find all long-eared dogs that do not have short, black hair". This seems like the simple way to do it: collect( Dog( ears=="long", not (hair=="short" && color=="black") ) But that doesn't parse. Some digging through the archives unearthed a mention of De Morgan's laws, which leads to: http://en.wikipedia.org/wiki/De_Morgan's_laws Which explains that I can instead write: collect( Dog( ears=="long", (hair!="short" || color!="black") ) Which, after some mental effort, turns out to be the right thing. However, had I not found the reference to De Morgan's Law, it would have taken me a long time to get there (if indeed I ever would have). The end result is also quite difficult to parse if you're not a logician, and thus not very user-friendly. Does anyone think it would be worthwhile to open a Jira requesting the ability to negate a constraint group? And, if I did open such a thing, do the developers think it would be reasonably easy to implement? -- Dirk Bergstrom [EMAIL PROTECTED] _ Juniper Networks Inc., Computer Geek Tel: 408.745.3182 Fax: 408.745.8905 ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
[rules-users] Issues when comparing attribute values to null
I am not sure if anyone else is having this issue or not, but I can not do in-line attribute compares to null. For instance. when ObjectA( objectBKey == null ) then objectBKey is a String in this case. This doesn't evaluate properly as the rule was firing even though the slot contained the key of ObjectB. Then I did this as a test when ObjectA( $objBKey : objectBKey ) not ObjectB( objectBKey == $objBKey ) then . This works because if the slot is populated there must be an ObjectB in the system with that unique key.If the $objBKey is null then there obviously is not an ObjectB in the system. I tried searching through the archieve but couldn't find anything for this issue. Also for what it's worth I'm using the official 4.0.5 release. Thanks in advance!

Brian,
I'm guessing that you mean the RuleAgent Class. The Javadoc on this
class gives more info.
Code sample (assuming that you have the BRMS setup as per the doc).
You'll need to change to whatever settings are appropriate for your
BRMS.
Properties prop = new Properties();
prop.setProperty("url",uri);
prop.setProperty("newInstance", "true");
prop.setProperty("localCacheDir", ".");
prop.setProperty("poll", "300"); // poll every 300 seconds
for hot deployment.
//Get a new RuleBase using these properties
RuleAgent agent = RuleAgent.newRuleAgent(prop);
RuleBase rb = agent.getRuleBase();
Then use the RuleBase as normal

RE: [rules-users] Hot Deployment
Hi Brian,
>> The goal here is to monitor the directory above for any changes to

If you want to monitor a local dir try using the "dir" property instead
of "url". In your case you would then have something like:
Properties prop = new Properties();
prop.setProperty("dir",
"c:/svn/code/sleuth/src/net/intellidata/sleuth/description/rules/");
prop.setProperty("poll", "300"); // poll every 300 seconds
for hot deployment.
I'm not sure if you would need these properties.
prop.setProperty("newInstance", "true");
prop.setProperty("localCacheDir", ".");
Have a look at Section 7.1.1. Deployment using the RuleAgent of the
online manual at
http://downloads.jboss.com/drools/docs/4.0.6.19326.GA/html/index.html

RE: [rules-users] Short circuiting evaluations on LHS
All facts are matched against all patterns upon insertion into working memory. The (Drools) techniques you describe affect the execution of activations (i.e. RHS) not pattern matching. I think (but it's a vague recollection) however that the sequence of patterns has an affect (so you want most restrictive first and least restrictive last). So my thought would be to try to add a pattern to the start of each rule that checks whether there are more than one survivor before the other (more expensive) patterns. Just a thought from what I recall - I haven't tried it:- rule "expensive" when ArrayList( size > 1 ) from collect( SuperClassOfAllFacts( ) ) someExpensivePattern( ) then something(); end _ From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Newman, Jason Sent: 03 April 2008 20:07 To: rules-users@lists.jboss.org Subject: [rules-users] Short circuiting evaluations on LHS I am currently using Drools 4.0 to determine the best choice out of a data set based on business rules. The rules eliminate (retract) facts until a single fact survives, and is used for additional processing. I have found Drools to be a great solution for this problem, and plan to role it out for additional survivor rules. My problem is in optimization - this is essentially a batch processing application, and speed is very important (of course it is - show me the case where it isn't, right?). Some of the later evaluations in the rules are fairly expensive (invoking complex queries from the database), and generally apply to only a small set of the use cases. For most use cases, the survivor will have been determined after the first or second rule, so I only want to perform the expensive evaluations if necessary. I have not found a way to avoid or schedule the LHS evaluations from firing when inserting the fact into the working memory. I have played around with agenda groups and rule flows, but haven't had any luck. The only way I can think of at this point is to break my rules into separate rule bases, and "manually" copy survivors from one working memory to the next, performing my own short circuiting outside of the rules being fired. Is there any other technique that I have missed? From a maintenance standpoint, I would prefer to be able to use one rule base/rule flow to manage the rules (there are only about 10 total rules, so the base is not very large - and I would have to break it into 4 or 5 different rule bases, which seems like it will be a pain across the 5 different areas I need to implement the rules.)
