.INDENT 3.5
The \fI\%scf\fP program performs \fIRestricted\fP Hartree\-Fock
calculations (the spatial part of the MOs is common for alpha and beta
spinorbitals).
.sp
It performs the following actions:
.INDENT 0.0
.IP 1. 3
Compute/Read all the one\- and two\-electron integrals, and store them
in memory
.IP 2. 3
Check in the \fI\%EZFIO\fP database if there is a set of MOs\&.
If there is, it will read them as initial guess. Otherwise, it will
create a guess.
.IP 3. 3
Perform the SCF iterations
.UNINDENT
.sp
For the keywords related to the SCF procedure, see the \fBscf_utils\fP
directory where you will find all options.
.sp
At each iteration, the MOs are saved in the \fI\%EZFIO\fP database. Hence,
if the calculation crashes for any unexpected reason, the calculation
can be restarted by running again the SCF with the same \fI\%EZFIO\fP
database.
.sp
To start again a fresh SCF calculation, the MOs can be reset by
running the qp_reset command.
.sp
The \fI\%DIIS\fP algorithm is implemented, as well as the \fI\%level\-shifting\fP
method. If the SCF does not converge, try again with a higher value of
\fBlevel_shift\fP\&.
