MAYBE

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

Strict Trs:
  { minus(minus(x)) -> x
  , minus(+(x, y)) ->
    *(minus(minus(minus(x))), minus(minus(minus(y))))
  , minus(*(x, y)) ->
    +(minus(minus(minus(x))), minus(minus(minus(y))))
  , f(minus(x)) -> minus(minus(minus(f(x)))) }
Obligation:
  runtime complexity
Answer:
  MAYBE

None of the processors succeeded.

Details of failed attempt(s):
-----------------------------
1) 'WithProblem (timeout of 60 seconds)' failed due to the
   following reason:
   
   Computation stopped due to timeout after 60.0 seconds.

2) 'Best' failed due to the following reason:
   
   None of the processors succeeded.
   
   Details of failed attempt(s):
   -----------------------------
   1) 'WithProblem (timeout of 30 seconds) (timeout of 60 seconds)'
      failed due to the following reason:
      
      Computation stopped due to timeout after 30.0 seconds.
   
   2) 'Fastest (timeout of 5 seconds) (timeout of 60 seconds)' failed
      due to the following reason:
      
      Computation stopped due to timeout after 5.0 seconds.
   
   3) 'Best' failed due to the following reason:
      
      None of the processors succeeded.
      
      Details of failed attempt(s):
      -----------------------------
      1) 'Polynomial Path Order (PS) (timeout of 60 seconds)' failed due
         to the following reason:
         
         The processor is inapplicable, reason:
           Processor only applicable for innermost runtime complexity analysis
      
      2) 'bsearch-popstar (timeout of 60 seconds)' failed due to the
         following reason:
         
         The processor is inapplicable, reason:
           Processor only applicable for innermost runtime complexity analysis
      
   

3) 'Innermost Weak Dependency Pairs (timeout of 60 seconds)' failed
   due to the following reason:
   
   We add the following weak dependency pairs:
   
   Strict DPs:
     { minus^#(minus(x)) -> c_1(x)
     , minus^#(+(x, y)) ->
       c_2(minus^#(minus(minus(x))), minus^#(minus(minus(y))))
     , minus^#(*(x, y)) ->
       c_3(minus^#(minus(minus(x))), minus^#(minus(minus(y))))
     , f^#(minus(x)) -> c_4(minus^#(minus(minus(f(x))))) }
   
   and mark the set of starting terms.
   
   We are left with following problem, upon which TcT provides the
   certificate MAYBE.

   Answer:
     MAYBE
   
   Empty strict component of the problem is NOT empty.


Arrrr..
