saealib.ArchiveUpdateStage#

class saealib.ArchiveUpdateStage(*, name='', label='', notation='')[source]#

Bases: Stage

Append evaluated offspring to archive and Pareto archive.

Reads state.evaluated_offspring and appends each individual to state.archive and state.pareto_archive (both are controlled mutable exceptions — append-only in-place updates).

Parameters:

name (str)
label (str)
notation (str)

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

ArchiveUpdateStage.__init__(*, name='', label='', notation='')#

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.

Return type:

None

ArchiveUpdateStage.contract()[source]#

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

Return type:: ComponentContract

ArchiveUpdateStage.execute(state)[source]#

Execute this stage and return the updated state.

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

ArchiveUpdateStage.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

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

Render this stage as a plain-text algorithmic line.

Parameters:

expand (bool)
indent (int)

Return type:

str
