Constructor Details

ZDT5

public ZDT5()

Constructs a ZDT5 test problem with 11 decision variables.

ZDT5

public ZDT5(int numberOfVariables)

Constructs a ZDT5 test problem with the specified number of decision variables.

Parameters:

numberOfVariables - the number of decision variables

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

newSolution

public Solution newSolution()

Description copied from interface: Problem

Returns a new solution for this problem. Implementations must initialize the variables so that the valid range of values is defined, but typically leave the actual value at a default or undefined state.

Specified by:

newSolution in interface Problem

Overrides:

newSolution in class ZDT

Returns:

a new solution for this problem
