saealib.Algorithm

class saealib.Algorithm

Bases: ABC

Base class for evolutionary algorithms.

Methods

__init__
ask	Generate one proposal batch from a read-only state view.
contract	Return the evolutionary-algorithm family contract.
create_pareto_archive	Create a ParetoArchive with the correct direction for the problem.
get_required_attrs	Return the list of attributes required for Population.
tell	Consume feedback and return the state changes it produced.

Method Details

Algorithm.__init__()
