  1. Support passing a class to the fitness, crossover, and mutation. https://github.com/ahmedfgad/GeneticAlgorithmPython/issues/342
  2. A new class called Validation is created in the new pygad/utils/validation.py script. It has a method called validate_parameters() to validate all the parameters passed while instantiating the pygad.GA class.
  3. Refactoring the pygad.py script by moving a lot of functions and methods to other classes in other scripts.
  4. The summary() method was moved to Helper class in the pygad/helper/misc.py script.
  5. The validation code in the __init__() method of the pygad.GA class is moved to the new validate_parameters() method in the new Validation class in the new pygad/utils/validation.py script. Moreover, the validate_multi_stop_criteria() method is also moved to the same class.
  6. The GA main workflow is moved into the new GAEngine class in the new pygad/utils/engine.py script. Specifically, these methods are moved from the pygad.GA class to the new GAEngine class: 1. run() 1. run_loop_head() 2. run_select_parents() 3. run_crossover() 4. run_mutation() 5. run_update_population() 2. initialize_population() 3. cal_pop_fitness() 4. best_solution() 5. round_genes()
  7. The pygad.GA class now extends the two new classes utils.validation.Validation and utils.engine.GAEngine.
  8. The version of the pygad.utils submodule is upgraded from 1.3.0 to 1.4.0.
  9. The version of the pygad.helper submodule is upgraded from 1.2.0 to 1.3.0.
  10. The version of the pygad.visualize submodule is upgraded from 1.1.0 to 1.1.1.
  11. The version of the pygad.nn submodule is upgraded from 1.2.1 to 1.2.2.
  12. The version of the pygad.cnn submodule is upgraded from 1.1.0 to 1.1.1.
  13. The version of the pygad.torchga submodule is upgraded from 1.4.0 to 1.4.1.
  14. The version of the pygad.kerasga submodule is upgraded from 1.3.0 to 1.3.1.
  15. Update the elitism after the evolution ends to fix issue where the best solution returned by the best_solution() method is not correct. https://github.com/ahmedfgad/GeneticAlgorithmPython/issues/337
  16. Fix a bug in calling the numpy.reshape() function. The parameter newshape is removed since it is no longer supported started from NumPy 2.4.0. https://numpy.org/doc/stable/release/2.4.0-notes.html#removed-newshape-parameter-from-numpy-reshape
  17. A minor change in the documentation is made to replace the newshape parameter when calling numpy.reshape().
  18. Fix a bug in the visualize/plot.py script that causes a warning to be given when the plot leged is used with single-objective problems.
  19. A new method called initialize_parents_array() is added to the Helper class in the pygad/helper/misc.py script. It is usually called from the methods in the ParentSelection class in the pygad/utils/parent_selection.py script to initialize the parents array.

  20. Add more tests about: 1. Operators (crossover, mutation, and parent selection). 2. The best_solution() method. 3. Parallel processing. 4. The GANN module. 5. The plots created by the visualize.

  21. Instead of using repeated code for converting the data type and rounding the genes during crossover and mutation, the change_gene_dtype_and_round() method is called from the pygad.helper.misc.Helper class.

  22. Fix some documentation issues. https://github.com/ahmedfgad/GeneticAlgorithmPython/pull/336
  23. Update the documentation to reflect the recent additions and changes to the library structure.
