One World mathematical Game Theory Seminar

The One World Mathematical Game Theory Seminar is an international online seminar whose goal is keeping our research community connected, allowing people to regularly meet and exchange ideas.

This seminar is a part of One World Seminars, currently held in probabilityPDEs,  Data  driven mathsWaves, Mathematical Methods for Arbitrary  Data Source (MADS) IMAGing and INvErse problem (IMAGINE)  and Optimization.

The seminar takes place biweekly, on Mondays at 15:00  CEST.
From the 30th of November – NEW! A short junior talk before the regular seminar talk.

January 25,  ON SOME CONTINUOUS TIME ALGORITHMS IN OPTIMIZATION AND GAME THEORY, SYLVAIN SORIN

We compare several algorithms in continuous time used in optimization and game theory.

The first three,  issued from  projected gradient dynamics,  correspond no-regret algorithms  and cover in particular “Replicator dynamics and  “”Local projection dynamics”.

Then we deal with  “Conditional gradient dynamics/’’“Global projection dynamics”  and finally “Frank-Wolfe algorithm’’/Best reply dynamics .
