Archimedes Talk by Professor Elias Koutsoupias on "The Communication Complexity of Combinatorial Auctions in Graphs"
8 September 2025
On Thursday, 11 September, 2025, from 11:00 am to 12:30 pm, at the Archimedes Amphitheatre (1 Artemidos Street, 15125, Marousi, Archimedes, Athena Research Center, Greece), Professor Elias Koutsoupias of the University of Oxford, UK, will deliver a talk on "The Communication Complexity of Combinatorial Auctions in Graphs."
Abstract: This talk is about truthful and non-truthful protocols for combinatorial auctions in which every item can be allocated to one of two agents (multigraphs), or more generally to a fixed number of agents (hypergraphs). We will discuss some recent results for the communication complexity of approximating the optimal social welfare for general monotone, subadditive, or XOS valuations.
