MAYBE

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

Strict Trs:
  { bsort(nil()) -> nil()
  , bsort(.(x, y)) ->
    last(.(bubble(.(x, y)), bsort(butlast(bubble(.(x, y))))))
  , last(nil()) -> 0()
  , last(.(x, nil())) -> x
  , last(.(x, .(y, z))) -> last(.(y, z))
  , bubble(nil()) -> nil()
  , bubble(.(x, nil())) -> .(x, nil())
  , bubble(.(x, .(y, z))) ->
    if(<=(x, y), .(y, bubble(.(x, z))), .(x, bubble(.(y, z))))
  , butlast(nil()) -> nil()
  , butlast(.(x, nil())) -> nil()
  , butlast(.(x, .(y, z))) -> .(x, butlast(.(y, z))) }
Obligation:
  innermost runtime complexity
Answer:
  MAYBE

None of the processors succeeded.

Details of failed attempt(s):
-----------------------------
1) 'empty' 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:

         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.
