MAYBE

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

Strict Trs:
  { active(f(x, y, z)) -> f(x, y, active(z))
  , active(f(b(), c(), x)) -> mark(f(x, x, x))
  , active(d()) -> mark(c())
  , active(d()) -> m(b())
  , f(x, y, mark(z)) -> mark(f(x, y, z))
  , f(ok(x), ok(y), ok(z)) -> ok(f(x, y, z))
  , proper(f(x, y, z)) -> f(proper(x), proper(y), proper(z))
  , proper(b()) -> ok(b())
  , proper(c()) -> ok(c())
  , proper(d()) -> ok(d())
  , top(mark(x)) -> top(proper(x))
  , top(ok(x)) -> top(active(x)) }
Obligation:
  innermost runtime complexity
Answer:
  MAYBE

None of the processors succeeded.

   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.
