list_iter_methods

Synopsis

List all Sherpa iterative fitting methods.

list_iter_methods()

Description

Sherpa includes multiple iterative fitting methods for fitting models to data. The list_iter_methods command lists these available methods, by name; it accepts no arguments.

The essence of an iterative fitting method is that the chosen fit optimization method can be called several times, until some criterion is met. The fit statistic and optimization methods are selected independently of the iterative fitting method. If the current iterative fitting method is set to the default value of 'none', then the optimization method is called only once when "fit()" is called.

Example

sherpa> list_iter_methods()

['none', 'primini', 'sigmarej']

The list_iter_methods() function lists the names of all iterative fitting methods available in Sherpa. Note that the default value for the current iterative fitting method is 'none'.
