Problem:
a() -> f(a())
f(f(f(f(f(x))))) -> b()

Proof:
Complexity Transformation Processor:
  strict:
   a() -> f(a())
   f(f(f(f(f(x))))) -> b()
  weak:

  Matrix Interpretation Processor:
   dimension: 1
   max_matrix:

    interpretation:
     [b] = 0,

     [f](x0) = x0 + 24,

     [a] = 135
    orientation:
     a() = 135 >= 159 = f(a())
