* See https://github.com/IOHprofiler/IOHexperimenter

|
|
* Handle only fitnesses that inherits from eoScalarFitness.
|
|
*
|
|
* @note: You're responsible of matching the fitness' encoding scalar type (IOH handle double and int, as of 2020-03-09).
|
|
* @note: You're responsible of calling `activate_logger` (if necessary), but it will call `target_problem` for you.
|
|
*
|
|
* You will need to pass the IOH include directory to your compiler (e.g. IOHexperimenter/build/Cpp/src/).
