4 c
5 c optim2: Routines for doing an off-line optimization with m1qn3
6 c after the ECCO forward and adjoint model have been run.
7 c
8 c optim_main - driver routine
9 c - optim_readparms :: read namelist files and number of control
10 c parameters
11 c - optim_sub :: driver for m1qn3
12 c + optim_readdata :: read control vector or gradient and cost
13 c function
14 c + optim_writedata :: write control vector
15 c + optim_store_m1qn3 :: store/restore the state of the optimizer
16 c + m1qn3_offline :: optimization routine
17 c > ddot :: LAPACK routine, required by m1qn3_offline
18 c
19 c Documentation:
20 c
21 c m1qn3_offline is based on m1qn3 v3.3, downloaded here:
22 c https://who.rocq.inria.fr/Jean-Charles.Gilbert/modulopt/
23 c optimization-routines/m1qn3/m1qn3.html
24 c To make work offline, the "save" statement have been replace
25 c by common blocks, by which variables are passed to
26 c optim_store_m1qn3 where they are stored on disk. In order to
27 c reduce the number of variables to be saved, some have been move
28 c down to where they are first used, e.g. barmul, tesf, etc.
29 c
30 c The driver routines optime_*.F are adapted from the original
31 c optim-pkg of the MITgcm.
