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

Proof:
 RT Transformation Processor:
  strict:
   a(x1) -> x1
   a(b(b(x1))) -> b(b(a(b(c(x1)))))
   b(c(x1)) -> a(x1)

  Matrix Interpretation Processor:
   dimension: 1
   interpretation:
    [c](x0) = x0 + 11,
    
    [b](x0) = x0 + 17,
    
    [a](x0) = x0 + 1
   orientation:
    a(x1) = x1 + 1 >= x1 = x1
    
    a(b(b(x1))) = x1 + 35 >= x1 + 63 = b(b(a(b(c(x1)))))
    
    b(c(x1)) = x1 + 28 >= x1 + 1 = a(x1)
