Venue

THE VENUE HAS CHANGED! The workshop will take place in the lecture rooms of the Hungarian Academy of Sciences at Országház u. 30, Budapest 1014.

Sponsors

The workshop is organised and partly financed by COST Action IC1205 on Computational Social Choice. Additional financial support received from the Mechanism Design research group of the Hungarian Academy of Sciences, the Institute for Political Science of the Hungarian Academy of Sciences and the Institute for Logic, Language and Computation at the University of Amsterdam is gratefully acknowledged.

The Hungarian Academy of Science and Eötvös Loránd University jointly organize the workshop

“100 years of matching theory in Hungary”to celebrate the seminal work of Dénes Kőnig and numerous other results in the field since then. The remit of the workshop is to explore the history, development and future directions of diverse matching problems occurring in discrete mathematics, combinatorial optimization, game theory and economics.

The program features a lecture on the history of matching theory, plenary talks on recent developments in important chapters and presentations on several real-world applications. Thus a key objective is to bring together established and young researchers of the related areas, in- and outside of Hungary.

The workshop is co-organized with the 12th Matching in Practice workshop, featuring keynote speaker Utku Ünver from Boston College.
