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 QTKBOS ... orients all.
	I(0) = 1
	I(activate) = 3 * x1 + 2	sigma(activate) = [1]
	I(zeros) = 3
	I(cons) = x1 + x2	sigma(cons) = [1,2]
	I(n__zeros) = 1
	I(tail) = 3 * x1	sigma(tail) = [1]
    PREC: tail > zeros > n__zeros > 0 = activate = cons
