This app implements the TD(0) algorithm, described in Sutton's classic bookReinforcement Learning: An Introduction, in Swift. There're 6046 unique states in total and the code trains by self-play using the TD(0) to update the state values for the states. In the first run of the app, ...

(for Kruskal's Algorithm) I have to implement Kruskal's Algorithm in Java. I have the part that I get the edges ordered by weight, but I am a little lost when I have to think the structure to save the sets of each tree. I thou......
