Problem:
 a(b(a(a(a(b(x1)))))) -> c(c(a(x1)))
 c(x1) -> b(a(a(a(b(x1)))))

Proof:
 Complexity Transformation Processor:

  Matrix Interpretation Processor:
   dimension: 1

    interpretation:
     [c](x0) = x0 + 1,
     
     [a](x0) = x0,
     
     [b](x0) = x0
    orientation:

     c(x1) = x1 + 1 >= x1 = b(a(a(a(b(x1)))))
