PyGAD 2.11.0

Release Date: 16 February 2021

  1. In the gene_space argument, the user can use a dictionary to specify the lower and upper limits of the gene. This dictionary must have only 2 items with keys low and high to specify the low and high limits of the gene, respectively. This way, PyGAD takes care of not exceeding the value limits of the gene. For a problem with only 2 genes, then using gene_space=[{'low': 1, 'high': 5}, {'low': 0.2, 'high': 0.81}] means the accepted values in the first gene start from 1 (inclusive) to 5 (exclusive) while the second one has values between 0.2 (inclusive) and 0.85 (exclusive). For more information, please check the Limit the Gene Value Range section of the documentation.
  2. The plot_result() method returns the figure so that the user can save it.
  3. Bug fixes in copying elements from the gene space.
  4. For a gene with a set of discrete values (more than 1 value) in the gene_space parameter like [0, 1], it was possible that the gene value may not change after mutation. That is if the current value is 0, then the randomly selected value could also be 0. Now, it is verified that the new value is changed. So, if the current value is 0, then the new value after mutation will not be 0 but 1.
