org.moeaframework.problem.BBOB2016.BBOB2016Problems

public class BBOB2016Problems
extends ProblemProvider

Problem provider for all problems in the BBOB 2016 test suite. This test suite consists of bi-objective problems constructed from two single-objective functions. Each single-objective function name follows the pattern:

     bbob_f001_i02_d05
 

In this case, we are requesting the second instance of the first BBOB function with five decision variables. The location of the optimum differs in each instance. To create the name of a BBOB 2016 problem supported by this problem provider, separate two function names a comma, such as:

     bbob_f001_i02_d05,bbob_f021_i02_d07
 

The dimension or number of decision variables must be identical in both functions. This also recognizes the problem name format used by the Coco Framework:

     bbob-biobj(bbob_f001_i02_d05__bbob_f021_i02_d07)
