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

Proof:
 RT Transformation Processor:
  strict:
   a(x1) -> b(x1)
   b(a(a(b(x1)))) -> a(a(b(b(a(x1)))))
  weak:
   
  Matrix Interpretation Processor:
   dimension: 1
   interpretation:
    [b](x0) = x0,
    
    [a](x0) = x0 + 8
   orientation:
    a(x1) = x1 + 8 >= x1 = b(x1)
