public class StandardProblems
extends ProblemProvider

Provides a standard set of test problems. The table below details the problems made available by this ProblemProvider. Problems are identified by a name, which is used as an argument to getProblem(String). Names with %D indicate that the number of objectives must be specified as an integer. For instance, DTLZ2_2 creates an instance of DTLZ2 with 2 objectives.
