** ~qmckl_slagel_splitting~
   :PROPERTIES:
   :Name:     qmckl_slagel_splitting
   :CRetType: double
   :FRetType: double precision
   :END: ~qmckl_slagel_splitting~ is used internally to apply a list of rank-1 updates while splitting an update if necessary.
   In case of a split it applies the first half of the update while putting the second half in waiting queue to be applied at the end.
  
   For a given update $u_j$ we define a threshold value $\epsilon_j$, which is the minimum value of 
   $1+v_j^TS^{-1}u_j$ for a non-singular matrix $S$. If $1+v_j^TS^{-1}u_j \geq \epsilon_j$, 
   the update is applied as usual. Otherwise, $u_j$ will be redefined as $\frac{u_j}{2}$, and the other half 
   (to be applied at the end) will be defined using vectors $\frac{u_{j'}}{2}$ and $v_{j'}^T=v_{j'}^T$.

   :END:

   This is the simplest of the available Sherman-Morrison-Woodbury
   kernels. It applies rank-1 updates one by one in the order
   that is given. It only checks if the denominator in the
   Sherman-Morrison formula is not too close to zero when an update is evaluated.
   It will exit with an error code of the denominator is too close to zero.

   The formula that is applied is
   \[
    (S + uv^T)^{-1} = S^{-1} - \frac{S^{-1} uv^T S^{-1}}{1 + v^T S^{-1} u}
   \]

   where
   $S$ is the Slater-matrix,
   $u$ and $v^T$ are the column and row vectors containing the updates,
   $S^{-1}$ is the inverse of the Slater-matrix.

The tests for the kernels are executed on datasets that are extracted from a run of QMC=Chem on Benzene (21 spin-up/21 spin down electrons) using 329 unique alpha determinants. The tests are run such that the kernels reject the computed inverse whenever the computed intermediate determinants or denominators are smaller than 1e-3. This is the default value in QMC=Chem.

   The simplest version of the generalised Sherman-Morrison-Woodbury kernels. It is used to apply two
   rank-1 updates at once. The formula used in this algorithm is called the Woodbury Matrix Identity
   \[
     (S + U V)^{-1}  =  S^{-1} - C B^{-1} D
   \]
   where
   $S$ is the Slater-matrix
   $U$ and $V$ are the matrices containing the updates and the canonical basis matrix
   $S^{-1}$ is the inverse of the Slater-matrix
   $C:= S^{-1}U$, a Dim $\times 2$ matrix
   $B := 1 + VC$, the $2 \times 2$ matrix that is going to be inverted
   $D := VS^{-1}$, a $2 \times Dim$ matrix

   This is a variation on the 'Naive' Sherman-Morrison kernel. Whenever the denominator $1+v_j^T S^{-1} u_j$ in
   the Sherman-Morrison formula is deemed to be too close to zero, the update $u_j$ is split in half:
   $u_j \rightarrow \frac{1}{1} u_j$. One half is applied immediately --necessarily increasing the value of the
   denominator because of the split-- while the other halve is put in a queue that will be applied when all the
   remaining updates have been treated. The kernel is executed recursively until the queue is eiter empty and all
   updates are applied successfully, or the size of the queue equals the number of initial updates. In the last
   case the Slater-matrix that would have resulted from applying the updates is un-invertable and therefore the
   kernel exits with an exit code.

   :END:

   The Woodbury 2x2 kernel with Sherman-Morrison and update splitting combines the low-level Woodbury 2x2 kernel
   and Sherman-Morrison with update splitting. For a given number of updates $N$ it splits the number of updates
   in blocks of two updates. The blocks of two updates are then applied one by one using Woodbury 2x2. If a block
   of updates fails, both updates in the block are applied with Sherman-Morrison instead, split if necessary and
   with their second half put in a queue. After all blocks are processed the remaining one update --in case there
   was an odd number of updates to begin with-- is also aplpied with Sherman-Morrison and split if necessary.
   The queue containing the collected second halves of all the processed updates is processed at the very end to
   avoid having many intermediate queues containing only a few updates that risks an increased probability
   of artificially created non-singular intermediate matrices, resulting from division up the total number of
   updates in blocks of three.

* Woodbury 3x3 and 2x2 with Sherman-Morrison and update splitting

   :END:

   The Woodbury 3x3 and 2x2 kernel with Sherman-Morrison and update splitting combines the low-level Woodbury 3x3 kernel,
   the Woobury 2x2 kernel and Sherman-Morrison with update splitting. It works the almost the same as Woodbury 3x3 with
   Sherman-Morrison and update splitting, except that when there is a remainder of two rank-1 updates, it is first tried
   with Woodbury 2x2 instead of sending them all to Sherman-Morrison with update splitting. For example, in the case of
   5 updates the updates are applied in 1 block of 3 updates end 1 block of 2 updates.
