# Orbital optimization
|
||||
|
||||
## Methods
|
||||
Different methods are available:
|
||||
- full hessian
|
||||
```
|
||||
qp set orbital_optimization optimization_method full
|
||||
```
|
||||
- diagonal hessian
|
||||
```
|
||||
qp set orbital_optimization optimization_method diag
|
||||
```
|
||||
- identity matrix
|
||||
```
|
||||
qp set orbital_optimization optimization_method none
|
||||
```
|
||||
|
||||
After the optimization the ezfio contains the optimized orbitals
|
||||
|
||||
## For a fixed number of determinants
|
||||
To optimize the MOs for the actual determinants:
|
||||
```
|
||||
qp run orb_opt
|
||||
```
|
||||
|
||||
## For a complete optimization, i.e, with a larger and larger wave function
|
||||
To optimize the MOs with a larger and larger wave function:
|
||||
```
|
||||
qp run optimization
|
||||
```
|
||||
|
||||
The results are stored in the EZFIO in "mo_optimization/result_opt",
|
||||
with the following format:
|
||||
(1) (2) (3) (4)
|
||||
1: Number of determinants in the wf,
|
||||
2: Cispi energy before the optimization,
|
||||
3: Cipsi energy after the optimization,
|
||||
4: Energy difference between (2) and (3).
|
||||
|
||||
The optimization process if the following:
|
||||
- we do a first cipsi step to obtain a small number of determinants in the wf
|
||||
- we run an orbital optimization for this wf
|
||||
- we do a new cipsi step to double the number of determinants in the wf
|
||||
- we run an orbital optimization for this wf
|
||||
- ...
|
||||
- we do that until the energy difference between (2) and (3) is
|
||||
smaller than the targeted accuracy for the cispi (targeted_accuracy_cipsi in qp edit)
|
||||
or the wf is larger than a given size (n_det_max_opt in qp_edit)
|
||||
- after that you can reset your determinants (qp reset -d) and run a clean Cispi calculation
|
||||
|
||||
### End of the optimization
|
||||
You can choos the number of determinants after what the
|
||||
optimization will stop:
|
||||
```
|
||||
qp set orbital_optimization n_det_max_opt 1e5 # or any number
|
||||
```
|
||||
## Weight of the states
|
||||
You can change the weights of the differents states directly in qp edit.
|
||||
It will affect ths weights used in the orbital optimization.
|
||||
|
||||
# Tests
|
||||
To run the tests:
|
||||
```
|
||||
qp test
|
||||
```
|
||||
|
||||
# Org files
|
||||
The org files are stored in the directory org in order to avoid overwriting on user changes.
|
||||
The org files can be modified, to export the change to the source code, run
|
||||
```
|
||||
./TANGLE_org_mode.sh
|
||||
mv *.irp.f ../.
|
||||

* Gradient
|
||||
|
||||
The gradient of the CI energy with respects to the orbital rotation
|
||||
is:
|
||||
(C-c C-x C-l)
|
||||
$$
|
||||
G(p,q) = \mathcal{P}_{pq} \left[ \sum_r (h_p^r \gamma_r^q - h_r^q \gamma_p^r) +
|
||||
\sum_{rst}(v_{pt}^{rs} \Gamma_{rs}^{qt} - v_{rs}^{qt} \Gamma_{pt}^{rs})
|
||||
\right]
|
||||
$$
|
||||
|
||||
|
||||
$$
|
||||
\mathcal{P}_{pq}= 1 - (p \leftrightarrow q)
|
||||
$$
|
||||
|
||||
$$
|
||||
G(p,q) = \left[
|
||||
\sum_r (h_p^r \gamma_r^q - h_r^q \gamma_p^r) +
|
||||
\sum_{rst}(v_{pt}^{rs} \Gamma_{rs}^{qt} - v_{rs}^{qt} \Gamma_{pt}^{rs})
|
||||
\right] -
|
||||
\left[
|
||||
\sum_r (h_q^r \gamma_r^p - h_r^p \gamma_q^r) +
|
||||
\sum_{rst}(v_{qt}^{rs} \Gamma_{rs}^{pt} - v_{rs}^{pt}
|
||||
\Gamma_{qt}^{rs})
|
||||
\right]
|
||||
$$
|
||||
|
||||
Where p,q,r,s,t are general spatial orbitals
|
||||
mo_num : the number of molecular orbitals
|
||||
$$h$$ : One electron integrals
|
||||
$$\gamma$$ : One body density matrix (state average in our case)
|
||||
$$v$$ : Two electron integrals
|
||||
$$\Gamma$$ : Two body density matrice (state average in our case)
|
||||
|
||||
The gradient is a mo_num by mo_num matrix, p,q,r,s,t take all the
|
||||
values between 1 and mo_num (1 and mo_num include).
|
||||
|
||||
To do that we compute $$G(p,q)$$ for all the pairs (p,q).

*** Term 1
|
||||
|

Without optimization the term 1 is :
|
||||
|
||||
do p = 1, mo_num
|
||||
do q = 1, mo_num
|
||||
do r = 1, mo_num

|

enddo
|

enddo
|

enddo
|

|

Since the matrix multiplication A.B is defined like :
|
||||
\begin{equation}
|
||||
c_{ij} = \sum_k a_{ik}.b_{kj}
|
||||
\end{equation}
|
||||
The previous equation can be rewritten as a matrix multplication

|

Without optimization the second term is :

do p = 1, mo_num
|

do q = 1, mo_num
|
||||
do r = 1, mo_num
|

do s = 1, mo_num

do t= 1, mo_num

|

grad(p,q) = grad(p,q) &

enddo
|
||||
enddo
|
||||
enddo
|
||||
enddo
|
||||
enddo
|
||||
|
||||
Using the bielectronic integral properties :
|
||||
get_two_e_integral(p,t,r,s,mo_integrals_map) = get_two_e_integral(r,s,p,t,mo_integrals_map)
|
||||
|
||||
Using the two body matrix properties :
|
||||
two_e_dm_mo(p,t,r,s) = two_e_dm_mo(r,s,p,t)
|
||||
|
||||
t is one the right, we can put it on the external loop and create 3
|
||||
indexes temporary array
|
||||
r,s can be seen as one index
|
||||
|
||||
By doing so, a matrix multiplication appears

*** Permutation, 2D matrix -> vector, transformation

In addition there is a permutation in the gradient formula :

\begin{equation}
|
||||
P_{pq} = 1 - (p <-> q)
|
||||
\end{equation}
|
||||
|
||||
We need a vector to use the gradient. Here the gradient is a
|
||||
antisymetric matrix so we can transform it in a vector of length
|
||||
mo_num*(mo_num-1)/2.
|
||||
|
||||
Here we do these two things at the same time.

* Orbital optimization program
|

|

This is an optimization program for molecular orbitals. It produces

orbital rotations in order to lower the energy of a truncated wave
|

function.
|
||||
This program just optimize the orbitals for a fixed number of
|

determinants. This optimization process must be repeated for different
|
||||
number of determinants.

** Calculations
|
||||
*** Algorithm
|
||||
|
||||
Here is the main algorithm of the optimization:
|
||||
- First of all we initialize some parameters and we compute the
|
||||
criterion (the ci energy) before doing any MO rotations
|
||||
- We compute the gradient and the hessian for the active MOs
|
||||
- We diagonalize the hessian
|
||||
- We compute a step and loop to reduce the radius of the
|
||||
trust region (and the size of the step by the way) until the step is
|
||||
accepted
|
||||
- We repeat the process until the convergence
|
||||
NB: the convergence criterion can be changed
