Unbiasing the initiator approximation in Full Configuration Interaction Quantum Monte Carlo
Khaldoon Ghanem, Alexander Y. Lozovoi, Ali Alavi
We identify and rectify a crucial source of bias in the initiator FCIQMC algorithm. Non-initiator determinants (i.e. determinants whose population is below the initiator threshold)…
