So I'm taking a course on game theory and as an intro he left us with this question. I'd like to have it solved fornext class as it is for bonus marks.I'm not sure how to add an attachment here so I will describe the game and board and hopefully someone can tell me how to upload a photo in the meantime.
The board:
Imagine a diamond made up of squares. (Like Fermats triangle) row 1 has one square, row 2 has 2...3 has 3 4 has 4 5 has 5 6 has 6 7 has 5 8 has 4 9 has 3 10 has 2 and 11 has 1.
On the upper left and bottom right sides of the diamond, the boxes touching the edge/side are labeled "b" and the upper right and bottom left are labeled "a"
The game: each player has a pile of blocks and takes turn placing a block anywhere in one of these squares. The object is to connect both a's together or both b's( depending on which was decided at the start) you also need to block the other player from winning.
The question: prove that player 1 ( whoever goes first) has a winning strategy.EDIT: added a photo in next post
My work. Since this is the first class we havnt learned anything so I'm just using what i know. If we assume that both players play optimally and that there is in fact a way to win with both players playing optimally, then played 1 has to have the winning stategy as he will alwas be one block ahead. Also since player 2 is second he will have to be the first one to block the other player to avoid him winning ) since optimally the shortest path would be ideal) That's about the best I can come up with. I also thought about amorous by contradiction but didn't know how to go about that. Ideas? Thoughts? Thanks. I'll post a pic of the board when I can
