I'm looking how to ask 2 rules, I wrote in the PIE window (see below) :
Code: Select all
hypothese(A):- etat(B), etat(C). hypothese(D):- etat(E), etat(F).
I try this: "hypothese(A):- etat(Y), etat(Z)."
but it ask me for unknown clause.
May be it's not possible ? but I rather think something is wrong in my code..!
Could you help me ?
