saealib.KNNConstraintObjectiveSet#

class saealib.KNNConstraintObjectiveSet(n_neighbors=50)[ソース]#

ベースクラス: TrainingSet

Retrieve the k nearest archive neighbours of candidate_x.

Analogue of KNNObjectiveSet for constraint surrogates. Returns the k-NN subset of (archive.x, archive.g) centred on candidate_x.

パラメータ:: n_neighbors (int) -- Number of nearest neighbours to retrieve.
例外:: ValueError -- If candidate_x is None, or if the archive has no constraint columns.

Methods

`__init__`
`build`	Return k nearest-neighbour archive points with raw constraint values.
`contract`	Return the training-set contract.
