2. Subgame Perfection for Extensive Form Games With Imperfect Information (Game Theory Playlist 7)

This episode continues our discussion that we started in the first episode and formally defines the concept of subgame and subgame optimality. We also define the concept of Subgame Perfect Nash Euilibrium (SPNE) in games with imperfect information. This more general definition can be applied in all extensive form games.
IIt's crucial to watch lecture videos in the proper order to ensure effective learning. This is because the concepts in each video build upon those introduced in previous videos. To help you with this, I recommend visiting my website, www.selcukozyurt.com, for a recommended course outline.

thank you for breaking down the definition systemically with an example. Makes it so much clearer and easier to understand. thanks again.

Thanks for the video. The concepts are briefly and very clearly explained. It really helped me a lot.

[@berkonver7621]

Thank you for the clear explanation.

Nice video. "If neither x or any of its successors are in an information set that contains nodes that are not successors of x" + "or x itself". In the case of x, technically you would need to adjust the definition to account for the fact that x itself in the information set x is in?

Thank you for such an amazing job you've been doing. I got a question about the second game at 11:00. Isn't the action C of player 1 a subgame?

[@arnantamang5448]

No

[@arnantamang5448]

The subgame beginning at that node should include all the successive nodes i.e A&B

Hi! At 14:20, will there be a subgame in which player 1 chooses L and R?

Now even in my dreams I can Identify Subgame and Proper Subgame 😁
