I will present some recent results in Algorithmic Game Theory and particularly in computing and approximating game and market equilibria. As you may have already known, the notion of the Nash equilibrium has captured the imagination of much of the computer science theory community, both for its many applications in the growing domain of online interactions and for its deep and fundamental mathematical structures. As the scale of typical internet applications increases, the problems of efficiently analyzing their game-theoretic properties become more pointed. I will discuss the recent results in settling several open questions about Nash equilibria. I will focus on the approximation and smoothed complexity of equilibrium computation in noncooperative two-player games. I will also address the extensions of these results to other equilibrium problems such as in trading and market economies.
Joint work conducted with Xi Chen (IAS, Princeton), Xiaotie Deng (The City University of Hong Kong); also with Li-Sha Huang (Google China), Paul Valiant (MIT), and Kyle Burke (Boston University).

The University of Waterloo acknowledges that much of our work takes place on the traditional territory of the Neutral, Anishinaabeg and Haudenosaunee peoples. Our main campus is situated on the Haldimand Tract, the land promised to the Six Nations that includes six miles on each side of the Grand River. Our active work toward reconciliation takes place across our campuses through research, learning, teaching, and community building, and is centralized within our Indigenous Initiatives Office.
