My 2 cents worth ...
First the 'single' slot activation is a bit mis-leading to me. I would
prefer to see it labelled 'any' slot activation since any slot that
is modifed can cause an activation (actually a 'match' of the pattern and
not necessarily an activation -- rules are activated). Following
The modified fact (rp-control (phase generate)) is being

When you use 'or' as you did in a rule, Jess actually
generates a rule for each of the or conditions. So in
your case if you executed the (rules) command you'd

The second rule is the 'missing' link. As you can see, if

My quick reaction to the suggestions for extensions
that "call one rule from another" is that:
1. in a 'pure' rule base system (whatever that is)
the rules are independent and this type of
tying rules together can lead to maintenance
problems. Consider Ernest's suggestion:
(defrul
The issue here seems to be that there is a subtle
difference between the 2 rules:
(defrule r1 (exists (a ?)) => )
and
(defrule r2 (a ?x) => )
If the facts (a b) (a c) and (a d) are asserted
before the reset is done the rule r2 will
result in 3 activations, whereas the rule r1
will not result
Finding facts requires a linear search through the list of facts.
Perhaps if the facts were contained in a hash table, indexed by
the fact's 'relation' name (1st element of the fact), the searching
for facts would be greatly improved.
