PyGAD 2.12.0 Documentation
## PyGAD 2.12.0
Release Date: 20 February 2021
1. 4 new instance attributes are added to hold temporary results after each generation: `last_generation_fitness` holds the fitness values of the solutions in the last generation, `last_generation_parents` holds the parents selected from the last generation, `last_generation_offspring_crossover` holds the offspring generated after applying the crossover in the last generation, and `last_generation_offspring_mutation` holds the offspring generated after applying the mutation in the last generation. You can access these attributes inside the `on_generation()` method for example.
2. A bug fixed when the `initial_population` parameter is used. The bug occurred due to a mismatch between the data type of the array assigned to `initial_population` and the gene type in the `gene_type` attribute. Assuming that the array assigned to the `initial_population` parameter is `((1, 1), (3, 3), (5, 5), (7, 7))` which has type `int`. When `gene_type` is set to `float`, then the genes will not be float but casted to `int` because the defined array has `int` type. The bug is fixed by forcing the array assigned to `initial_population` to have the data type in the `gene_type` attribute. Check the [issue at GitHub](#27): #27
