[rules-users] How to chose witch rules are going to be evaluated?

[Edson Tirelli]

    The only way to prevent parts of a rule of being evaluated is to use
control facts:

when
    SomeControlFact( someCondition == true )
    eval( ..someHeavyEvaluation... )
then

    In the above case, the eval will only be evaluated when the control fact
matches.

    Another way of doing it is moving your expensive "calculation" to the
consequence of a rule and inserting the result as a fact. This way you have
control of when it is executed.
