Companion Notebook¶
The NSGA2Generator can be run on multi-objective optimization problems purely from Xopt's YAML configuration files. This notebook demonstrates how to set up the configuration file, how to run the optimization algorithm, and how to load the data into python and plot the results. At the end, we demonstrate how to restart an optimization from one of NSGA2Generator's checkpoint files.

Calling the Xopt Runner CLI Tool¶
Xopt includes a tool caled xopt-run which will load the Xopt object from the YAML configuration file and call Xopt.run() on it to perform the optimization until the termination condition is achieved.

Loading and Plotting Data¶
The YAML file specified that data will be output to the directory nsga2_output within the working directory of the script (ie assets/yaml_runner_example). In here, there will be several files.
populations.csv: Each completed population is recorded to this filedata.csv: Contains all evaluated invidualslog.txt: A record of all log messages the genreator emitted during its runvocs.txt: A copy of the variable, objectives, and constraints (VOCs) definitionscheckpoints/: This directory contains checkpoint files which are used with thecheckpoint_filekey of the generator to restart an optimization.

Restoring from Checkpoints¶
In this section, we will restart the optimizer from one of its saved checkpoints. This allows us to carry on an optimization that was previously terminated with no loss of information. The checkpoint is specified in the YAML file using the key checkpoint_file. Any additional settings in the generator will override the settings included in the checkpoint. The evaluation function still needs to be defined and should be identical to what was used during the original run.
