MAYBE

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

Strict Trs:
  { filter(X1, X2, X3) -> n__filter(X1, X2, X3)
  , filter(cons(X, Y), 0(), M) ->
    cons(0(), n__filter(activate(Y), M, M))
  , filter(cons(X, Y), s(N), M) ->
    cons(X, n__filter(activate(Y), N, M))
  , activate(X) -> X
  , activate(n__filter(X1, X2, X3)) -> filter(X1, X2, X3)
  , activate(n__sieve(X)) -> sieve(X)
  , activate(n__nats(X)) -> nats(X)
  , sieve(X) -> n__sieve(X)
  , sieve(cons(0(), Y)) -> cons(0(), n__sieve(activate(Y)))
  , sieve(cons(s(N), Y)) ->
    cons(s(N), n__sieve(filter(activate(Y), N, N)))
  , nats(N) -> cons(N, n__nats(s(N)))
  , nats(X) -> n__nats(X)
  , zprimes() -> sieve(nats(s(s(0())))) }

Answer:
  MAYBE

None of the processors succeeded.

Details of failed attempt(s):
-----------------------------
1) 'empty' failed due to the following reason:

2) 'Best' failed due to the following reason:
   
   None of the processors succeeded.
   
   Details of failed attempt(s):
   -----------------------------
   1) 'WithProblem (timeout of 60 seconds)' failed due to the
      following reason:

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

      3) 'Fastest (timeout of 5 seconds) (timeout of 60 seconds)' failed
         due to the following reason:
         
         None of the processors succeeded.
         
         Details of failed attempt(s):
         -----------------------------
         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.
