一群人将目前最常用的算法作成的一个library
包括了quantum monte carlo, exact diagnolization,dmrg
If you happen need to use those algorithm
this is a good one to get started.
Escpecially for people that are either doing qmc but need to
compare their result with dmrg or the oppsite. http://alps.comp-phys.org:16080/mediawiki-1.9.3/index.php/Main_Page
