saealib.InitializationStage

class saealib.InitializationStage(initializer, provider, problem)

ベースクラス: Stage

Wrap an Initializer as a Stage.

Delegates to initializer.initialize(provider, problem) and returns the resulting OptimizationState. The state argument passed to execute() is ignored — initialization always produces a fresh state from scratch.

This stage is intended for use at the head of a user-defined Pipeline when the initializer itself should participate in the pipeline abstraction (e.g. to build custom init-then-optimize flows or to inspect / swap the initialization step via Pipeline["initialization"]).

パラメータ:

• initializer (Initializer) -- The concrete initializer (e.g. LHSInitializer).

• provider (ComponentProvider) -- Component provider forwarded to Initializer.initialize().

• problem (Problem) -- The optimization problem.

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	Render this stage as a LaTeX algorithmic line.
to_text	Render this stage as a plain-text algorithmic line.
