Checkpoint 2 Notes

TTT Strategy

For each of the following board states, if you are playing as X and it's your turn, which action would you take? Why?

| O | O | | O | X | X | O |
---+---+--- ---+---+--- ---+---+--- ---+---+--- X | X | | X | X | O | O | |
---+---+--- ---+---+--- ---+---+--- ---+---+--- | | | | O | | | |

For the first board I would play 5 because I would win. For the second board I would play 5 because I would block O from winning. For the third board I would play 0 because I would be guaranteed a board where I could always win next turn. For the third board I would play 4 because it gets me closer to winning and blocks O from getting closer

Initial game state

You can get the inital game state using game.get_initial_state(). What is the current and future reward for this state? What does this mean?

The current reward state is 0, which means the game is either incomplete or it has ended in a draw. In this case, the game is incomplete.

The future reward state is 0, which means if both players play optimally, the game will end in a draw.
