Genetic Algorithms in Elixir: possible typo (page 52)
In the paragraph about Optimizing Cargo Loads, I think there is the word project incorrectly used, and it should be probably product.
You have ten products, labeled A-J, with corresponding weights: [10, 6, 8, 7, 10, 9, 7,11, 6, 8]. Each project has an associated profit margin: [6, 5, 8, 9, 6, 7, 3, 1, 2, 6] and the weight limit of the cargo is 40. The image on page 53 shows the loads and their corresponding weights and profit margin.
