MAYBE

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

Strict Trs:
  { +(x, 0()) -> x
  , +(+(x, y), z) -> +(x, +(y, z))
  , +(0(), x) -> x
  , +(s(x), s(y)) -> s(s(+(x, y)))
  , *(x, 0()) -> 0()
  , *(0(), x) -> 0()
  , *(s(x), s(y)) -> s(+(*(x, y), +(x, y)))
  , *(*(x, y), z) -> *(x, *(y, z))
  , app(nil(), l) -> l
  , app(cons(x, l1), l2) -> cons(x, app(l1, l2))
  , sum(app(l1, l2)) -> +(sum(l1), sum(l2))
  , sum(nil()) -> 0()
  , sum(cons(x, l)) -> +(x, sum(l))
  , prod(app(l1, l2)) -> *(prod(l1), prod(l2))
  , prod(nil()) -> s(0())
  , prod(cons(x, l)) -> *(x, prod(l)) }

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