saealib.InitializationStage#

class saealib.InitializationStage(initializer, provider, problem)[source]#

Bases: 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"]).

Parameters:

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.

Method Details

InitializationStage.__init__(initializer, provider, problem)[source]#

Initialize base Stage attributes.

Parameters:

name (str, optional) – Override the class-level name.
label (str, optional) – Override the class-level label.
notation (str, optional) – Override the class-level notation.
initializer (Initializer)
provider (ComponentProvider)
problem (Problem)

Return type:

None

InitializationStage.contract()[source]#

Return this stage’s structural and direct state-access contract.

Return type:: ComponentContract

InitializationStage.execute(state)[source]#

Execute this stage and return the updated state.

Parameters:: state (OptimizationState) – Current optimization state.
Returns:: Updated state.
Return type:: OptimizationState

InitializationStage.to_pseudocode(*, expand=False, indent=0)#

Render this stage as a LaTeX algorithmic line.

Parameters:

indent (int) – Current indentation level (number of \State indent steps).

Returns:

LaTeX algorithmic fragment.

Return type:

str

InitializationStage.to_text(*, expand=False, indent=0)#

Render this stage as a plain-text algorithmic line.

Parameters:

expand (bool)
indent (int)

Return type:

str
