Constructor Details

TransformVariablesAffine

public TransformVariablesAffine(BBOBFunction function,
 double[][] M,
 double[] b)

Constructs a new instance of the affine transformation.

Parameters:

function - the inner function

M - the rotation component of the affine transform

b - the translation component of the affine transform

Method Details

evaluate

public void evaluate(Solution solution)

Description copied from interface: Problem

Evaluates the solution, updating the solution's objectives in place. Algorithms must explicitly call this method when appropriate to evaluate new solutions or reevaluate modified solutions.

Parameters:

solution - the solution to be evaluated
