MAYBE

We are left with following problem, upon which TcT provides the
certificate MAYBE.

Strict Trs:
  { max(nil()) -> 0()
  , max(cons(x, nil())) -> x
  , max(cons(x, cons(y, xs))) -> if1(ge(x, y), x, y, xs)
  , if1(true(), x, y, xs) -> max(cons(x, xs))
  , if1(false(), x, y, xs) -> max(cons(y, xs))
  , ge(x, 0()) -> true()
  , ge(0(), s(x)) -> false()
  , ge(s(x), s(y)) -> ge(x, y)
  , del(x, nil()) -> nil()
  , del(x, cons(y, xs)) -> if2(eq(x, y), x, y, xs)
  , if2(true(), x, y, xs) -> xs
  , if2(false(), x, y, xs) -> cons(y, del(x, xs))
  , eq(0(), 0()) -> true()
  , eq(0(), s(y)) -> false()
  , eq(s(x), 0()) -> false()
  , eq(s(x), s(y)) -> eq(x, y)
  , sort(nil()) -> nil()
  , sort(cons(x, xs)) ->
    cons(max(cons(x, xs)), sort(del(max(cons(x, xs)), cons(x, xs)))) }

            following reason:
            
            The input cannot be shown compatible
         
         2) 'Polynomial Path Order (PS) (timeout of 60 seconds)' failed due
            to the following reason:

         -----------------------------
         1) 'Bounds with minimal-enrichment and initial automaton 'match''
            failed due to the following reason:
            
            match-boundness of the problem could not be verified.
         
         2) 'Bounds with perSymbol-enrichment and initial automaton 'match''
            failed due to the following reason:
            
            match-boundness of the problem could not be verified.
