Hands-On Neuroevolution with Python

Saving the results of the experiment

The experiment results reported and saved in textual and graphical representations (SVG files). We start by printing general performance statistics as follows:

    print("\nBest ever fitness: %f, genome ID: %d"           % (best_ever_goal_fitness, best_id))    print("\nTrial elapsed time: %.3f sec" % (elapsed_time))    print("Random seed:", seed)

The first three lines of the preceding code print the best ever fitness score obtained among all the generations of evolution to the console. After that, we print the experiment's elapsed time and the random seed value used.

If we requested to save or show visualizations, the corresponding functions are invoked:

    # Visualize the experiment results    show_results = not silent if save_results ...
