saealib.AskStage

class saealib.AskStage(algorithm, n_offspring=None, cbmanager=None)

ベースクラス: Stage

Generate offspring candidates via the algorithm's ask() method.

Writes the offspring population to state.offspring.

パラメータ:

• algorithm (Algorithm) -- The evolutionary algorithm that generates candidates.

• n_offspring (int or None) -- Number of offspring to request. Passed directly to algorithm.ask(). None lets the algorithm decide.

• cbmanager (CallbackManager or None) -- If provided, PostCrossoverEvent / PostMutationEvent / PostAskEvent are dispatched through this manager.

Methods

__init__	Initialize base Stage attributes.
contract	Return this stage's structural and direct state-access contract.
execute	Execute this stage and return the updated state.
to_pseudocode	Expand into per-operator lines via Algorithm.ask_notation.
to_text	Render this stage as a plain-text algorithmic line.

Method Details
