BBOB¶

class ioh.iohcpp.suite.BBOB(self, problem_ids: collections.abc.Sequence[int], instances: collections.abc.Sequence[int] = [1], dimensions: collections.abc.Sequence[int] = [5])¶

Bases: RealBase

Suite with BBOB functions included in IOH.

This class is an iterator for problems, you can define a set of problems to iterate over.

Parameters:

problem_ids (list[int]) – A list of problems ids to include in this instantiation of the suite
instances (list[int]) – A list of problem instances to include in this instantiation of the suite
dimensions (list[int]) – A list of problem dimensions to include in this instantiation of the suite

Attributes Summary

`dimensions`	The dimensions of all problems contained in the current suite, as a new numpy array (int32).
`instances`	The instance ids of all problems contained in the current suite, as a new numpy array (int32).
`name`	The name of the suite.
`problem_ids`	The ids of all problems contained in the current suite, as a new numpy array (int32).

Methods Summary

`attach_logger`(self, arg, /)	Attach a logger to the problem to track the performance and internal variables.
`detach_logger`(self)	Remove the specified logger from the problem
`reset`(self)	Reset the state variables of the current problem.
