Idea for AI Project   "Our future will be written in code."

1) Take a book in electronic format like a Jane Austen book from project Gutenberg. Take the last chapter in that book. Remove all the spaces.

Now write a computer program to put all the spaces back. You can easily count how many it got right since you have the original text.

  1. Do it using Hidden Markov Models based on a frequency dictionary of English.

  2. Do it using a Genetic Algorithm using an oracle based on the same frequency dictionary.
