We consider the following Problem:

  Strict Trs:
    {  zeros() -> cons(0(), zeros())
     , U11(tt(), L) -> U12(tt(), L)
     , U12(tt(), L) -> s(length(L))
     , length(nil()) -> 0()
     , length(cons(N, L)) -> U11(tt(), L)}
  StartTerms: basic terms
  Strategy: innermost

Certificate: MAYBE

Proof:
  The input cannot be shown compatible
