Hello Ian,

The ALPS model library supports defining random parameters with the following functions that can be used in your parameter file: random() gaussian_random() normal_random() gaussian_random(0,2)

Attached you find also an example using the DISORDERSEED to have different random seeds. The example is using the dmrg implementation of the mps_optim code.

Best regards, Michele

Hi!

Is it possible to have a site-dependent random parameter using DMRG in ALPS? For example in every a different random value for the Magnetic Field Strength acting on the model is assigned to each site.

Thanks, Ian Felismino
