Abstract
Density matrix renormalization group method introduced recently by Whi te proves to be highly successful for interacting one and quasi-on dim ensional systems. We compare this new method with the conventional num erical renormalization group. We discuss the common goal and different strategies used in both methods. The limitations of the new method as well as the ways to overcome them are explored.
