Dear ALPS users,
The ALPS MPS code can print 'TruncatedWeight' to estimate the error of the simulation. I have a question:
What is the meaning of this quantity and the relation with the truncation error in traditional DMRG simulation?
For Fig. 5 in Computer Physics Communications, 185(12):3430 – 3440, 2014., the quantity may be summed as the final truncation error after a sweep.
Thanks a lot!
Best regards,
Rongyang Sun
