show_method

Context: info

Synopsis

Display the optimization method

Syntax

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

Description

The show_method command displays the current optimization method and parameters.

The command output looks like:

Optimization Method: NelderMead
name         = simplex
ftol         = 1.1920928955078125e-07
maxfev       = None
initsimplex  = 0
finalsimplex = 9
step         = None
iquad        = 1
verbose      = 0

Examples

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.


Changes in CIAO 4.12

PAGER environment variable is no-longer used

Paging of the screen output is now handled by Python rather than using an external tool defined by the PAGER environment variable. This means that paged output should now appear in Jupyter notebooks.


Bugs
