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

Proof:
 RT Transformation Processor:
  strict:
   a(x1) -> b(x1)
   a(b(b(c(x1)))) -> c(c(a(a(a(a(x1))))))
  weak:
   
  Matrix Interpretation Processor:
   dimension: 1
   interpretation:
    [c](x0) = x0 + 9,
    
    [b](x0) = x0 + 7,
    
    [a](x0) = x0 + 9
   orientation:
    a(x1) = x1 + 9 >= x1 + 7 = b(x1)
    
    a(b(b(c(x1)))) = x1 + 32 >= x1 + 54 = c(c(a(a(a(a(x1))))))
   problem:
    strict:
     a(b(b(c(x1)))) -> c(c(a(a(a(a(x1))))))
    weak:
     a(x1) -> b(x1)
