quad_approx module¶
Quadratic approximations of functions from the optimization history.
- class gemseo.post.quad_approx.QuadApprox(opt_problem)[source]¶
Bases:
OptPostProcessor
Quadratic approximation of a function.
And cuts of the approximation.
The function index can be passed as option.
- Parameters:
opt_problem (OptimizationProblem) – The optimization problem to be post-processed.
- Raises:
ValueError – If the JSON grammar file for the options of the post-processor does not exist.
- check_options(**options)¶
Check the options of the post-processor.
- execute(save=True, show=False, file_path=None, directory_path=None, file_name=None, file_extension=None, fig_size=None, **options)¶
Post-process the optimization problem.
- Parameters:
save (bool) –
If
True
, save the figure.By default it is set to True.
show (bool) –
If
True
, display the figure.By default it is set to False.
file_path (str | Path | None) – The path of the file to save the figures. If the extension is missing, use
file_extension
. IfNone
, create a file path fromdirectory_path
,file_name
andfile_extension
.directory_path (str | Path | None) – The path of the directory to save the figures. If
None
, use the current working directory.file_name (str | None) – The name of the file to save the figures. If
None
, use a default one generated by the post-processing.file_extension (str | None) – A file extension, e.g. ‘png’, ‘pdf’, ‘svg’, … If
None
, use a default file extension.fig_size (FigSizeType | None) – The width and height of the figure in inches, e.g.
(w, h)
. IfNone
, use theOptPostProcessor.DEFAULT_FIG_SIZE
of the post-processor.**options (OptPostProcessorOptionType) – The options of the post-processor.
- Returns:
The figures, to be customized if not closed.
- Raises:
ValueError – If the
opt_problem.database
is empty.
- static unnormalize_vector(xn_array, ivar, lower_bounds, upper_bounds)[source]¶
Unormalize a variable with respect to bounds.
- DEFAULT_FIG_SIZE = (9.0, 6.0)¶
The default width and height of the figure, in inches.
- SR1_APPROX = 'SR1'¶
- property figures: dict[str, Figure]¶
The Matplotlib figures indexed by a name, or the nameless figure counter.
- materials_for_plotting: dict[Any, Any]¶
The materials to eventually rebuild the plot in another framework.
- opt_problem: OptimizationProblem¶
The optimization problem.
