9 | ! This module minimizes incremental 4Dvar quadratic cost function !
|
---|
10 | ! using a preconditioned version of the conjugate gradient algorithm !
|
---|
11 | ! proposed by Mike Fisher (ECMWF). !
|
---|
12 | ! !
|
---|
13 | ! In the following, M represents the preconditioner. Specifically, !
|
---|
14 | ! !
|
---|
15 | ! M = I + SUM_i [ (mu_i-1) h_i (h_i)'], !
|
---|
16 | ! !
|
---|
17 | ! where mu_i can take the following values: !
|
---|
18 | ! !
|
---|
19 | ! Lscale= 1: mu_i = lambda_i !
|
---|
20 | ! Lscale=-1: mu_i = 1 / lambda_i !
|
---|
21 | ! Lscale= 2: mu_i = SQRT (lambda_i) !
|
---|
22 | ! Lscale=-2: mu_i = 1 / SQRT(lambda_i) !
|
---|
23 | ! !
|
---|
24 | ! where lambda_i are the Hessian eigenvalues and h_i are the Hessian !
|
---|
25 | ! eigenvectors. For Lscale=-1 the preconditioner is an approximation !
|
---|
26 | ! of the inverse Hessian matrix constructed from the leading Hessian !
|
---|
27 | ! eigenvectors. A full description is given in Fisher and Courtier !
|
---|
28 | ! (1995), ECMWF Tech Memo 220. !

|
---|
30 | ! Given an initial model state X(0), gradient G(0), descent direction !
|
---|
31 | ! d(0), and trial step size tau(1), the minimization algorithm at the !
|
---|
32 | ! k-iteration is : !
|
---|
33 | ! !
|
---|
34 | ! (1) Run tangent linear model initialized with trial step, Xhat(k): !
|
---|
35 | ! !
|
---|
36 | ! Xhat(k) = X(k) + tau(k) * d(k) (Eq 5a) !
|
---|
37 | ! !
|
---|
38 | ! (2) Run adjoint model to compute gradient at trial point, Ghat(k): !
|
---|
39 | ! !
|
---|
40 | ! Ghat(k) = GRAD[ f(Xhat(k)) ] (Eq 5b) !
|
---|
41 | ! !
|
---|
42 | ! (3) Compute optimum step size, alpha(k): !
|
---|
43 | ! !
|
---|
44 | ! alpha(k) = tau(k) * <d(k), G(k)> / !
|
---|
45 | ! !
|
---|
46 | ! (<d(k),G(k)> - <d(k), Ghat(k)>) (Eq 5c) !
|
---|
47 | ! !
|
---|
48 | ! here <...> denotes dot product !
|
---|
49 | ! !
|
---|
50 | ! (4) Compute new starting point (TLM increments), X(k+1): !
|
---|
51 | ! !
|
---|
52 | ! X(k+1) = X(k) + alpha(k) * d(k) (Eq 5d) !
|
---|
53 | ! !
|
---|
54 | ! (5) Compute gradient at new point, G(k+1): !
|
---|
55 | ! !
|
---|
56 | ! G(k+1) = G(k) + (alpha(k) / tau(k)) * (Ghat(k) - G(k)) (Eq 5e) !
|
---|
57 | ! !
|
---|
58 | ! overwrite G(k+1) in the NetCDF for latter use. !
|
---|
59 | ! !
|
---|
60 | ! (6) Orthogonalize new gradient, G(k+1), against all previous !
|
---|
61 | ! gradients [G(k), ..., G(0)], in reverse order, using the !
|
---|
62 | ! modified Gramm-Schmidt algorithm. Notice that we need to !
|
---|
63 | ! save all inner loop gradient solutions. !
|
---|
64 | ! !
|
---|
65 | ! For the preconditioned case the appropriate inner-product !
|
---|
66 | ! for the orthonormalizatio is <G,MG>. !
|
---|
67 | ! !
|
---|
68 | ! (7) Compute new descent direction, d(k+1): !
|
---|
69 | ! !
|
---|
70 | ! beta(k+1) = <G(k+1),M G(k+1)> / <G(k),M G(k)> (Eq 5g) !
|
---|
71 | ! !
|
---|
72 | ! d(k+1) = - MG(k+1) + beta(k+1) * d(k) (Eq 5f) !
|
---|
73 | ! !
|
---|
74 | ! After the first iteration, the trial step size is: !
|
---|
75 | ! !
|
---|
76 | ! tau(k) = alpha(k-1) !
|
---|
77 | ! !
|

---|
79 | ! state variable arrays as temporary arrays. !
