Bases: Exception

Raised when an error related to the preference incorporated space is encountered.

Initialize self. See help(type(self)) for accurate signature.

Implements the preference incorporated space mapping which uses the classification preference.

Parameters:

  • scalarizers (List[Type[GLIDEBase]]) – Scalarizers to be used to create the PIS. Should include atleast one scalarizer. NIMBUS should not be included as it is added automatically.

  • utopian (np.ndarray) – The utopian point of the problem.

  • nadir (np.ndarray) – The nadir point of the problem.

  • rho (float, optional) – The augmentation factor used in the different scalarizers. Defaults to 1e-6.
