  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:
      
      The weightgap principle applies (using the following nonconstant
      growth matrix-interpretation)
      
      The following argument positions are usable:
        Uargs(f) = {1}
      
      TcT has computed the following matrix interpretation satisfying
      not(EDA) and not(IDA(1)).
      
        [f](x1, x2) = [1] x1 + [1] x2 + [7]
                                           
            [g](x1) = [1] x1 + [7]         
                                           
            [s](x1) = [1] x1 + [6]         
      
      The following symbols are considered usable
      
        {f, g}
      
      The order satisfies the following ordering constraints:
      
        [f(x, x)] = [2] x + [7] 
                  ? [2] x + [14]
                  = [f(g(x), x)]
                                
           [g(x)] = [1] x + [7] 
                  > [1] x + [6] 
                  = [s(x)]      
                                
      
      Further, it can be verified that all rules not oriented are covered by the weightgap condition.
