> [b] There's a great intro lecture on this by Papadimitriou himself at https://www.youtube.com/watch?v=TUbfCY_8Dzs

Just a point of correction, this lecture is by Constantinos Daskalakis and not Christos Papadimitriou. Both were authors on the PPAD work that you refer to, however.

Well, that's embarrassing. I watched the lecture a long while ago, and somehow my puny little organic brain misremembered the lecturer.

Thank you for the correction.

And apologies to Daskalakis!
