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

Proof:
 RT Transformation Processor:
  strict:
   a(x1) -> b(x1)
   b(b(b(c(x1)))) -> c(c(a(a(b(a(x1))))))
  weak:
   
  Matrix Interpretation Processor:
   dimension: 1
   interpretation:
    [c](x0) = x0 + 12,
    
    [b](x0) = x0 + 17,
    
    [a](x0) = x0 + 7
   orientation:
    a(x1) = x1 + 7 >= x1 + 17 = b(x1)
    
    b(b(b(c(x1)))) = x1 + 63 >= x1 + 62 = c(c(a(a(b(a(x1))))))
   problem:
    strict:
     a(x1) -> b(x1)
    weak:
     b(b(b(c(x1)))) -> c(c(a(a(b(a(x1))))))
