VectorObjective

class desdeo_problem.problem.VectorObjective(name, evaluator, lower_bounds=None, upper_bounds=None, maximize=None)[source]

Bases: VectorObjectiveBase

An objective function vector with one or more objective functions.

To be renamed to Objective

Attributes:
__name (List[str]): Names of the various objectives in a list __evaluator (Callable): The function that evaluates the objective values __lower_bounds (Union[List[float], np.ndarray), optional): Lower bounds

of the objective values. Defaults to None.

__upper_bounds (Union[List[float], np.ndarray), optional): Upper bounds
of the objective values. Defaults to None.

__maximize (List[bool]): List of boolean to determine whether the
objectives are to be maximized. All false by default

__n_of_objects (int): The number of objectives

Parameters:

name (List[str]) – Names of the various objectives in a list
evaluator (Callable) – The function that evaluates the objective values
lower_bounds (Union[List[float], np.ndarray), optional) – Lower bounds of the objective values. Defaults to None.
upper_bounds (Union[List[float], np.ndarray), optional) – Upper bounds of the objective values. Defaults to None.
maximize (Optional[List[bool]]) – List of boolean to determine whether the objectives are to be maximized. All false by default
