* Theoretical background
Here we describe the main theoretical background and definitions of the
Configuration (CFG) based CIPSI algorithm. The outline of the document is as follows.
First, we give some definitions of the CFG many-particle basis follwed by the
definitions of the overlap, one-particle, and two-particle matrix-elements. Finally,
an algorithm is presented for the sigma-vector (\[ \sigma \]-vector defined later) calculation using

\(\ket{^S\Phi_i}\).
The coefficients \(O^b_{a,k}\) depend only on the number of SOMOs
in \(\Phi_i\).

spin part of the wavefunction (see Eq: [[Eq:definebasis3]]) which is
encoded in the BFs as shown below in Eq: [[Eq:definebasis5]].

encoded in the BFs as shown below in Eq:~\ref{Eq:definebasis5}.
\begin{equation}\begin{equation}
\label{Eq:definebasis3}

$i$ is the index of the CFG and $j$ determines the coupling.
The bonded functions are made up of products of slater determinants. There are
three types of determinants, first, the closed shell pairs \[(i\bar{i})\]. Second,
the open-shell singlet pairs \[(i,j)\] which are expanded as \[(i,j) = \frac{\ket{i\bar{j}}-\ket{\bar{i}j}}{\sqrt{2}}\]. Third, the

the open-shell singlet pairs \((b\ c)\) which are expanded as
\((b\ c) = \frac{\ket{b\bar{c}}-\ket{\bar{b}c}}{\sqrt{2}}\). Third, the

** Overlap of the wavefunction
Once the wavefunction has been expanded in terms of the CSFs, the most fundamental
operation is to calculate the overlap between two states. The overlap in the
basis of CSFs is defined as shown in Eq:~\ref{Eq:defineovlp1}.

\end{equation}
Where the sum is over the CSFs \[k\] and \[l\] corresponding to the \[i\]
and \[j\] CFGs respectively. The overlap between the CSFs can be expanded in terms
of the BFs using the definition given in Eq:~\ref{Eq:definebasis2} and Eq:~\ref{Eq:definebasis3}

redefine the CSFs in terms of a linear combination of BFs such that

orthogonalization matrix \[\mathbf{\tilde{O}}_i\] which is given by
