public class MaF15 extends LSMOP implements AnalyticalProblem
The MaF15 test problem, which is an inverted version of the LSMOP8 test problem with N_k=2 and N_ns=20.. This problem exhibits the following properties:
  • Convex Pareto front
  • Partially separable decision variables
  • Non-uniform correlations between decision variables and objectives

  • Constructor Details

    • MaF15

      public MaF15(int numberOfObjectives)
      Constructs an MaF15 test problem with the specified number of objectives.
      Parameters:
      numberOfObjectives - the number of objectives for this problem

  • Method Details

    • generate

      public Solution generate()
      Description copied from interface: AnalyticalProblem
      Returns a randomly-generated solution using the analytical solution to this problem. The exact behavior of this method depends on the implementation, but in general (1) the solutions should be non-dominated and (2) spread uniformly across the Pareto front.

      It is not always possible to guarantee these conditions. For example, a discontinuous / disconnected Pareto surface could generate dominated solutions, and a biased problem could result in non-uniform distributions. Therefore, we recommend callers filter solutions through a NondominatedPopulation, in particular one that maintains a spread of solutions.

      Furthermore, some implementations may not provide the corresponding decision variables for the solution. These implementations should indicate this by returning a solution with 0 decision variables.

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