Éva Tardos (born 1 October 1957) is a Hungarian mathematician and the Jacob Gould Schurman Professor of Computer Science at Cornell University, known for her work in theoretical computer science. For her work, she has received the Fulkerson Prize (1988), the Dantzig Prize (2006), and the IEEE John von Neumann Medal (2019).
Tardos's research interest is algorithms and algorithmic game theory. Her work focuses on the design and analysis of efficient methods for combinatorial optimization problems on graphs or networks. She has done some work on network flow algorithms like approximation algorithms for network flows, cut, and clustering problems. Her recent work focuses on algorithmic game theory and simple auctions.
