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

Proof:
 RT Transformation Processor:
  strict:
   a(x1) -> b(x1)
   a(x1) -> b(b(c(x1)))
   c(a(b(x1))) -> a(c(a(x1)))
  weak:
   
  Matrix Interpretation Processor:
   dimension: 1
   interpretation:
    [c](x0) = x0 + 22,
    
    [b](x0) = x0 + 20,
    
    [a](x0) = x0 + 13
   orientation:
    a(x1) = x1 + 13 >= x1 + 20 = b(x1)
    
    a(x1) = x1 + 13 >= x1 + 62 = b(b(c(x1)))
    
    c(a(b(x1))) = x1 + 55 >= x1 + 48 = a(c(a(x1)))

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