Input TRS:
    1: zeros() -> cons(0(),n__zeros())
    2: tail(cons(X,XS)) -> activate(XS)
    3: zeros() -> n__zeros()
    4: activate(n__zeros()) -> zeros()
    5: activate(X) -> X
Number of Rules: 5
Direct POLO(Sum) ... orients all.
	I(0) = 0
	I(activate) = x1 + 2
	I(zeros) = 1
	I(cons) = x1 + x2
	I(n__zeros) = 0
	I(tail) = x1 + 3
