Hello,

I have question about multi-site terms support in hamiltonian definition.
I found some mention about that in ALPS workshop (2006)
In recent wiki announced that
`Extensions to more complex terms, such as 3- and 4-site terms are in preparation and will be included here as soon as the ALPS libraries support such terms.`

There is possibility to include now such terms?

Not yet - we need to find someone to code it. This will not be hard but someone needs to do it.

Will arise huge problems in DMRG methods after including such milti-site terms?

No, why should there be huge problems?
