MetaData¶

class ioh.iohcpp.MetaData(self, problem_id: int, instance: int, name: str, n_variables: int, optimization_type: ioh.iohcpp.OptimizationType, final_target: float = 1e-08, fixed_dimension: bool = False, fixed_instance: bool = False)¶

Bases: object

Problem meta data. Contains static information about problems, such as their name and id.

Parameters:

problem_id (int) – The id of the problem
instance (int) – The instance of the problem
name (str) – The name of the problem
n_variables (int) – The problem dimensionality
optimization_type (OptimizationType) – Enum value, denoting if this is a maximization or minimization problem
final_target (float) – The final target of the function
fixed_dimension (bool) – Whether the problem has this dimension whatever dimension was requested
fixed_instance (bool) – Whether the problem has this instance whatever instance was requested

Attributes Summary

`final_target`	(self) -> float
`fixed_dimension`	Whether the problem has one dimension, n_variables, whatever dimension was requested (the CEC2013 and graph problems)
`fixed_instance`	Whether the problem has one instance, instance, whatever instance was requested (the CEC2013 and graph problems)
`instance`	The instance number of the current problem
`n_variables`	The number of variables (dimension) of the current problem
`name`	The name of the current problem
`optimization_type`	The type of problem (maximization or minimization)
`problem_id`	The id of the problem within its suite
