I try to calculate recursive function:
f(x, y) = 0 if x = 0;
f(x, y) = 1 if x = 1;
f(x, y) = y*y*f(x-2,y) if x>1.
I tried this way:
f(0,_,0).
f(1,_,1).
f(X,Y,Z):-
X>1,
XX is X-2,
ZZ = Y*Y*Z,
f(XX,Y,ZZ).
I can only obtain true/false. How can I calculate value of this function?
Thank you very much!
Your last rule looks a little odd to me. I'd try something like this:
