Since you said sparsediag was the code to use, then how to set the number of eignstates to calculate in the parameter file or command line? I can not find the answer in the turtorials.

Dear ALPS users,
I have been running LiveALPS from my USB flash drive and I can't
get access to the internet. I could not find any information anywhere on
how to resolve this issue. Would you be able to help me out ?

Subject: [ALPS-users] a question about fulldiag
Content-Type: text/plain; charset="us-ascii"
Hi, all
I currently tend to calculate the energy of the lowest 4 states of a fermion system with fulldiag of ALPS. However, since the system has 12 eigenstates in total and fulldiag gives all of them, the time it takes is a little bit long. So, my question is: is there any way to limit the number of eigenstates that fulldiag calculates? for example, the lowest 4 states.

sparsediag is the code to use in this case
