We are pleased to invite you to the IEOR Seminar by Dr. Srinivas Arigapudi on Monday, Feb 23, 9:30 am. The details are given below.
TITLE: Sampling Dynamics in Coordination Games
SPEAKER: Dr. Srinivas Arigapudi, IIT Kanpur
DATE & TIME: Monday, Feb 23, 2026, 9:30 am
VENUE: IEOR 211 (Seminar room), Dept. of IEOR.
ABSTRACT: Coordination games feature two types of equilibria: pure
equilibria, where players successfully coordinate their actions, and mixed
equilibria, where players frequently experience miscoordination. We
investigate learning dynamics where agents observe the actions of a random
sample of their opponents. We first show that when all agents have the
same sample size, whether it is small or large, their behavior converges
to one of the pure coordinated equilibria. We then show that stable
miscoordination can persist when some agents make decisions based on small
samples while others rely on large samples.
SPEAKER BIO: Srinivas Arigapudi is a game theorist specializing in
evolutionary game theory, a field which examines the behavior of large
populations of strategically interacting agents. His research interests
include agent-based modeling and market design. He holds a Ph.D. in
Economics from the University of Wisconsin–Madison, an M.S. in
Quantitative Economics from the Indian Statistical Institute, Delhi, and a
B.Tech. in Engineering Physics from IIT Delhi. He was a postdoctoral
fellow in the Faculty of Data and Decision Sciences at the Technion–Israel
Institute of Technology and is currently a faculty member at IIT Kanpur.
