10 c This header file contains those parameters that are monitoring
11 c the state of the off-line optimization procedure. One
12 c optimization cycle is considered to consist of a forward/adjoint
13 c model run followed by a cost function minimization that then
14 c yields a new guess for the control vector:
15 c
16 c optimcycle i: xx(i) --> fc(i) adxx(i) --> xx(i+1)

39 c The off-line optimization part:
40 c ===============================
41 c
42 c Starting an optimization experiment implies setting optimcycle to
43 c zero. During cycle number I the model is called first, then the
44 c offline optimization is run. The latter provides a new guess for
45 c the vector of control variables for the next cycle I+1.
46 c
47 c optimcycle - cycle number of the off-line optimization.
