Archimedes Seminar by Mihalis Yannakakis, Percy K. and Vida L. W. Hudson Professor of Computer Science, Columbia University, USA

On Wednesday 25 June, 2025, from 5:00 pm to 6:00 pm, at the Archimedes Amphitheatre (1 Artemidos Street, 15125, Marousi, Archimedes, Athena Research Center, Greece), Mihalis YannakakisPercy K. and Vida L. W. Hudson Professor of Computer Science at Columbia University, USA, will deliver an Archimedes Seminar on "Computing a Fixed Point of Contraction Maps in Polynomial Queries."

Abstract: 

We give an algorithm for finding an approximate fixed point of a contraction map under the L-infinity norm in polynomial number of queries; specifically in O( k log(1/epsilon)) queries, where k is the dimension and epsilon is the approximation error. Joint work with Xi Chen and Yuhao Li.
