I made an example in the search.ipynb notebook explaining the intuition behind genetic algorithms and how the existing functions in search.py can be understood and used for other problems, as the current notebook didn't explain the functions well. It is a simple phrase generation problem. I have tried my best to explain step-by-step how one can solve the problem using the existing functions. I have also implemented a well commented GUI version for students to play around with. I would like some feedback on my work and whether I should submit a PR
