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

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

  Matrix Interpretation Processor:
   dimension: 1
   interpretation:
    [b](x0) = x0 + 18,
    
    [a](x0) = x0 + 29,
    
    [c](x0) = x0 + 3
   orientation:
    a(c(x1)) = x1 + 32 >= x1 + 21 = c(b(x1))
    
    a(x1) = x1 + 29 >= x1 + 54 = b(b(b(x1)))
    
    b(c(b(x1))) = x1 + 39 >= x1 + 32 = a(c(x1))
