MAYBE

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

Strict Trs:
  { fib(N) -> sel(N, fib1(s(0()), s(0())))
  , sel(s(N), cons(X, XS)) -> sel(N, activate(XS))
  , sel(0(), cons(X, XS)) -> X
  , fib1(X, Y) -> cons(X, n__fib1(Y, n__add(X, Y)))
  , fib1(X1, X2) -> n__fib1(X1, X2)
  , add(X1, X2) -> n__add(X1, X2)
  , add(s(X), Y) -> s(add(X, Y))
  , add(0(), X) -> X
  , activate(X) -> X
  , activate(n__fib1(X1, X2)) -> fib1(activate(X1), activate(X2))
  , activate(n__add(X1, X2)) -> add(activate(X1), activate(X2)) }

  innermost runtime complexity
Answer:
  MAYBE

None of the processors succeeded.

         -----------------------------
         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.
