Genetic Algorithms in Elixir: String.bag_distance() is unsorted evaluation
In final example in Chapter 3, is String.bag_distance() correct choice for the fitness_function()? It will return 1 if two strings contain same characters no matter the order of the characters. This will cause terminate? to terminate the run with the wrong string most of the time.

You can use String.jaro_distance/2. That should work better. I’ll fix this example. You’ll use Jaro Distance later as well.
