Constructor Detail

C3_DTLZ4

public C3_DTLZ4(int numberOfVariables,
                int numberOfObjectives)
Constructs a C3-DTLZ4 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

C3_DTLZ4

public C3_DTLZ4(int numberOfObjectives)
Constructs a C3-DTLZ4 test problem with the specified number of objectives. This is equivalent to calling new DTLZ4(numberOfObjectives+9, numberOfObjectives).

Parameters:
numberOfObjectives - the number of objectives for this problem
Method Detail

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 DTLZ4
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 may 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

generate

public Solution generate()
Description copied from interface: AnalyticalProblem
Returns a randomly-generated solution using the analytical solution to this problem. Note however that discontinuous Pareto surfaces may result in some solutions generated by this method being dominated by other generated solutions. It is therefore recommended using a NondominatedPopulation to removed dominated solutions prior to using the generated reference set.

The generated solutions should be spread uniformly across the entire Pareto frontier; however, this is a suggestion and is not a requirement of this interface.

Specified by:
generate in interface AnalyticalProblem
Overrides:
generate in class DTLZ4
Returns:
a randomly-generated Pareto optimal solution to this problem
