Input Problem:    innermost runtime-complexity with respect to
  Rules:
    {  rev1(0(), nil()) -> 0()
     , rev1(s(X), nil()) -> s(X)
     , rev1(X, cons(Y, L)) -> rev1(Y, L)
     , rev(nil()) -> nil()
     , rev(cons(X, L)) -> cons(rev1(X, L), rev2(X, L))
     , rev2(X, nil()) -> nil()
     , rev2(X, cons(Y, L)) -> rev(cons(X, rev(rev2(Y, L))))}

Proof Output:    
  The input cannot be shown compatible
