Constructor Details

C1_DTLZ1

public C1_DTLZ1(int numberOfVariables,
 int numberOfObjectives)

Constructs a C1-DTLZ1 test problem with the specified number of variables and objectives.

Parameters:

numberOfVariables - the number of variables for this problem

numberOfObjectives - the number of objectives for this problem

C1_DTLZ1

public C1_DTLZ1(int numberOfObjectives)

Constructs a C1-DTLZ1 test problem with the specified number of objectives. This is equivalent to calling new DTLZ1(numberOfObjectives+4, numberOfObjectives).

Parameters:

numberOfObjectives - the number of objectives for this problem

Method Details

getNumberOfConstraints

public int getNumberOfConstraints()

Description copied from interface: Problem

Returns the number of constraints defined by this problem.

Specified by:

getNumberOfConstraints in interface Problem

Overrides:

getNumberOfConstraints in class AbstractProblem

Returns:

the number of constraints defined by this problem

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.

Specified by:

evaluate in interface Problem

Overrides:

evaluate in class DTLZ1

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 DTLZ

Returns:

a new solution for this problem
