Test functions

Module that includes three simple test function classes that can be used for validation and testing of the methodology

class topsearch.potentials.test_functions.Camelback

Description

Six-hump camel function: sfu.ca/~ssurjano/camel6.html

function(position: NDArray[Any, Any]) → float

Return function evaluated at position

gradient(position: NDArray[Any, Any]) → NDArray[Any, Any]

Return gradient vector evaluated at position

hessian(position: NDArray[Any, Any]) → NDArray[Any, Any]

Construct the 2x2 Hessian matrix of second derivatives

class topsearch.potentials.test_functions.Quadratic

Description

Simple quadratic centered at (0, 0, 0, … )

function(position: NDArray[Any, Any]) → float

Return the quadratic function value

class topsearch.potentials.test_functions.Schwefel

Description

Schwefel function: https://www.sfu.ca/~ssurjano/schwef.html

function(position: NDArray[Any, Any]) → NDArray[Any, Any]

Returns the Schwefel function evaluated at position
