MAYBE
EmptyProcessor
- Strict TRS:
    sub(0(),0()) -> 0()
    sub(0(),s(x)) -> 0()
    sub(s(x),0()) -> s(x)
    sub(s(x),s(y)) -> sub(x,y)
    zero(cons(x,xs)) -> zero2(sub(x,x),cons(x,xs))
    zero(nil()) -> zero2(0(),nil())
    zero2(0(),cons(x,xs)) -> cons(sub(x,x),zero(xs))
    zero2(0(),nil()) -> nil()
    zero2(s(y),cons(x,xs)) -> zero(cons(x,xs))
    zero2(s(y),nil()) -> zero(nil())
- Signature:
    {sub/2,zero/1,zero2/2} / {0/0,cons/2,nil/0,s/1}
- Obligation:
    innermost derivational complexity wrt. signature {0,cons,nil,s,sub,zero,zero2}
The problem is still open.
