check_domination(→ Tuple[numpy.ndarray, numpy.ndarray])

Checks if newly evaluated and archived solutions are non_dominated.
desdeo_emo.utilities.non_dominated.check_domination(new: numpy.ndarray, archive: numpy.ndarray) → Tuple[numpy.ndarray, numpy.ndarray][source]

Checks if newly evaluated and archived solutions are non_dominated.

Parameters:

  • new (np.ndarray) – Newly evaluated solution’s fitness values (should be a 2D array).

  • archive (np.ndarray) – Archive of non-dominated solutions (also a 2D array, must be mutually non-dominated).

Raises:

ValueError – If the new array is not a 2D array.

Returns:

Two arrays of indices that are

non-dominated in the new and archive arrays respectively.

Return type:

Tuple[np.ndarray, np.ndarray]
