Improved performance and dtype bug fixes for FermionOperator2nd. (!1277) · Merge requests · Vicentini Filippo / netket · GitLab

Vicentini Filippo requested to merge github/fork/jwnys/faster_fermions into master Jul 27, 2022

Created by: jwnys

Improved performance:

max_conn_size is typically lower now, since we count only one connected element per hermitian conjugate pair

Bug fixes:

Copy did not have the correct dtype due to inplace changes
Double terms did not cancel

Added a few extra tests.
