Selected Full Configuration Interaction with stochastic selection
and PT2.
.sp
This program performs a CIPSI\-like selected CI using a
stochastic scheme for both the selection of the important Slater
determinants and the computation of the PT2 correction. This
CIPSI\-like algorithm will be performed for the lowest states of
the variational space (see \fBdeterminants n_states\fP). The
FCI program will stop when reaching at least one the two following
conditions:
.INDENT 0.0
.IP \(bu 2
number of Slater determinants > \fBdeterminants n_det_max\fP
.IP \(bu 2
abs(PT2) less than \fBperturbation pt2_max\fP
.UNINDENT
.sp
The following other options can be of interest:
.INDENT 0.0
.TP
.B \fBdeterminants read_wf\fP
When set to \fBfalse\fP, the program starts with a ROHF\-like Slater
determinant as a guess wave function. When set to \fBtrue\fP, the
program starts with the wave function(s) stored in the \fI\%EZFIO\fP
directory as guess wave function(s).
.TP
.B \fBdeterminants s2_eig\fP
When set to \fBtrue\fP, the selection will systematically add all the
necessary Slater determinants in order to have a pure spin wave
function with an \ewidehat{S^2} value corresponding to
\fBdeterminants expected_s2\fP\&.
.UNINDENT
.sp
For excited states calculations, it is recommended to start with
cis or cisd guess wave functions, eventually in
a restricted set of MOs, and to set \fBdeterminants s2_eig\fP
to \fBtrue\fP\&.
