show_method

Synopsis

Display the optimization method

show_method([outfile=None, clobber=False] )

Description

The show_method command displays the current optimization method and parameters.

• outfile - name of the file in which to store the information
• clobber - a Boolean switch which indicates whether or not the 'outfile' should be overwritten, if the file already exists; default=False

The command output looks like:

Optimization Method: NelderMead
name         = simplex
ftol         = 1.19209289551e-07
maxfev       = None
initsimplex  = 0
finalsimplex = 9
step         = None
iquad        = 1
verbose      = 0

The behavior of the screen output is determined by the user's $PAGER environment variable setting, which is usually a variant of "more." To disable paging within show_all() - i.e. print the entire contents, even if it scrolls offscreen - change this setting to "cat" before starting Sherpa:

unix% setenv PAGER cat

unix% sherpa

Example 1

sherpa> show_method()

Print the optimization method to the screen.

Example 2

sherpa> show_method("sherpa.method", True)

Write the optimization method to the file "sherpa.method", clobbering any existing file with the same name.
