Code refactoring for a material science algorithm.

摘要

We lived in a world that is constantly changing and we have to keep change with it to stay at pace. The DMRG++ is a powerful numerical variational technique that is a free and open source implementation of the DMRG algorithm. It work using a generic implementation of C++ templates, it has a very few software dependencies and is a very friendly user-interface. DMRG++ makes the programmer writing new models and geometries easy and fast and is a bug-free algorithm by using a generic DMRG implementation engine. In this work you will see the transcode to a faster, ligthweigth and simpler programming language called LUA trying to make this algorithm more universal easier to use and in the way to expand the use of it in other applications.
