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

Backward Induction is a concept that only works in extensive form games with perfect information. However, we can extend the idea of subgame perfection to extensive form games with imperfect information in a way similar to the idea of backward induction. This episode compares and contrasts two extensive form games (one with perfect information and the other with imperfect information) and argues how an idea akin to backward induction can be used to solve for the subgame perfect Nash equilibrium of the games with imperfect information.
It'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.

I really like the way you set this up as the same exact game just with and without perfect information! I think it makes the idea of information sets and Nash Equilibrium for both perfect information and asymmetric information sequential games super clear and easier to understand! Love the explanation! Sometimes I like to draw a dotted ellipse around the decision where a player makes a decision to sort of represent a "cloud of uncertainty". Great video overall!

Thank you for grouping the videos as per their main topic. I wanted to know if the playlists build on top of each other? Would you recommend us to view them from playlist 1 to 10 and so on? Or is there any set order in which you want us to view the topics?
@selcukozyurt
@selcukozyurt 3 года назад
Yes playlists are built on top of each other. So, I recommend starting from playlist 1 and then playlist 2, and so on. Also vidoes are built on top of each other. Therefore, in a given episode, I strongly suggest going from video 1 first, then second and so on. Finally, you can check the syllabus that I follow in my courses (please see the description below any video).

thank you so much for this video. for the second example with imperfect information for player 2, how would one find Nash equilibrium that is not sub perfect?? I have understood how to find SPNE for such a case , but how to just find NE??

Pausing at 16:29, what happens if in the blue markered tree, the right node has payoff of say (3, 1) and the left node is a prisoners dilema game (Hence with no NE in the encirlced inperfect game.). What can we say about NE and SPNE in terms of pure strategies for the whole game. What are the NE and SPNE(if any)?

Hello:) Can you, please, explain, why does the player 1 chooses R, not L? Cause 3 is more than 2.
@zhixinsun1015
@zhixinsun1015 2 года назад
Because if the player chooses L, the player 2 will choose U, which gives him 2, not 0. This behavior leads to that player 1 will eventually get 1, not 3.

Is this known as "Generalized Backwards Induction?" I'm reading Leyton-Brown & Shoham (2008) and find no mention of this algorithm. But it seems Kaminski came up with it after 2008.

if player 2 doesnt know at what node she is, UNTIL 1 has played. if R then she chooses D and if L she chooses U. If she is at R, why would she think of what is going to happen L, because she doesnt know R and L. She just know her own node! This reasoning is going circular and doesnt match.
