Constructor Details

TransformVariablesXHat

public TransformVariablesXHat(BBOBFunction function,
 long seed)

Constructs a new instance of the x-hat transformation.

Parameters:

function - the inner function

seed - the random number seed controlling which decision variables are negated

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
