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

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