8     c
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)

38     c The off-line optimization part:
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.
