hello,
thank you for answer, i understand the bakward chaining but i still have a problem with firing rules:
i have 3 rules R1, R2, R3, that activate the same rule R4
R1-> R4
R2-> R4
R3 -> R4
but the rule R4 is activated only by R3 (the last one declared) even if i assert the facts that fire R1 or R2
how can i remedy to this?
