AHELP for CIAO 4.9 Sherpa v1

list_methods

Context: methods

Synopsis

List all Sherpa optimization methods.

Syntax

list_methods()

Description

Sherpa includes several different optimization methods that can be used to fit models to data. This function lists all available methods, by name; it accepts no arguments.

The primary task of Sherpa is to fit a model M(p) to a set of observed data, where the vector p denotes the model parameters. An optimization method is one that is used to determine the vector of model parameter values, p0, for which the chosen fit statistic is minimized.

Example

sherpa> list_methods()

['levmar', 'moncar', 'simplex', 'neldermead']

The list_methods() function lists the names of all fit optimization methods available in Sherpa:
