constraints_history module

A constraints plot.

Classes:

ConstraintsHistory(opt_problem)

Plot of the constraint function history with line charts.

class gemseo.post.constraints_history.ConstraintsHistory(opt_problem)[source]

Bases: gemseo.post.opt_post_processor.OptPostProcessor

Plot of the constraint function history with line charts.

Indicate the violation with color on the background.

The plot method requires the constraint names to plot. It is possible either to save the plot, to show the plot or both.

Attributes
  • opt_problem (OptimizationProblem) – The optimization problem.

  • database (Database) – The database generated by the optimization problem.

  • out_data_dict (Dict[Any,Any]) – The data dict to eventually rebuild the plot in another framework.

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.

Return type

None

Methods:

check_options(**options)

Check the options of the post-processor.

execute([save, show, file_path, …])

Post-process the optimization problem.

Attributes:

figures

The Matplotlib figures indexed by a name, or the nameless figure counter.

output_files

The paths to the output files.

check_options(**options)

Check the options of the post-processor.

Parameters
  • **options – The options of the post-processor.

  • options (Union[int, float, str, bool, Sequence[str]]) –

Raises

InvalidDataException – If an option is invalid according to the grammar.

Return type

None

execute(save=True, show=False, file_path=None, directory_path=None, file_name=None, file_extension=None, **options)

Post-process the optimization problem.

Parameters
  • save (bool) – If True, save the figure.

  • show (bool) – If True, display the figure.

  • file_path (Optional[Union[str, pathlib.Path]]) – The path of the file to save the figures. If the extension is missing, use file_extension. If None, create a file path from directory_path, file_name and file_extension.

  • directory_path (Optional[Union[str, pathlib.Path]]) – The path of the directory to save the figures. If None, use the current working directory.

  • file_name (Optional[str]) – The name of the file to save the figures. If None, use a default one generated by the post-processing.

  • file_extension (Optional[str]) – A file extension, e.g. ‘png’, ‘pdf’, ‘svg’, … If None, use a default file extension.

  • **options – The options of the post-processor.

  • options (Union[int, float, str, bool, Sequence[str]]) –

Returns

The figure, to be customized if not closed.

Raises

ValueError – If the opt_problem.database is empty.

Return type

Dict[str, matplotlib.figure.Figure]

property figures

The Matplotlib figures indexed by a name, or the nameless figure counter.

property output_files

The paths to the output files.
