class TrialRemoveAVB : public feasst::Trial

Attempt to remove a particle of type “a” with a bias for site_index_a to be in the aggrevation volume (AV) of site_index_t (“t” for target) of particle of type “t”.

See TrialAddAVB for derivation of the acceptance probability that is the reverse of this Trial.

There are modifications to make for this reverse move considering that the acceptance probability is computed before the removal takes place.

The number of sites to select in the AV already contains the site added from the old state,

\( N^{s,AV}_a + 1 \rightarrow N^{s,AV}_a \).
