Hi,
The best is if you look at the tutorials: http://alps.comp-phys.org/mediawiki/index.php/ALPS_2_Tutorials:DMRG-01_DMRG#...
You have:
1. put a <LATTICES> tag around your graph.
2. give a name to the graph
3. set the LATTICE_LIBRARY and LATTICE accordingly.
For example:
LATTICE_LIBRARY="my_lattice.xml"
LATTICE="open chain lattice with special edges"

Dear All,
I want to ask how to use graph to define the lattice. I write a graph file named as “a.xml”. In the parameter file, I use: GRAPH="C:\alpsproject\lattice\a.xml"; .
The a.xml file is as the following. However the output is “could not find”. I want to ask how to use it. Thank you very much.
Sincerely,
Huaiming Guo
