is invoked from the main level of X-PLOR.
- <minimize-powell-statement> :==
-
- DROP=<real>
- designates the expected initial drop in
energy (default: 0.001). Experience has shown that values
between 10 and 100 work best.
- NPRInt=<integer>
- is the frequency of the energy printout
(default: 1).
- NSTEp=<integer>
- is the maximum number of
minimization cycles (default: 500).
- TOLGradient=<real>
- stops minimization if the norm of
the gradient of
is smaller than the specified number
(default: 0.0001).
