Regret-based dynamics have been introduced and studied in the context of discrete-time r play. Here we carry out the corresponding analysis in continuous time. We observe that, in c to (smooth) fictitious play or to evolutionary models, the appropriate state space for this ana the space of distributions on the product of the players’ pure action spaces (rather than the pr their mixed action spaces). We obtain relatively simple proofs for some results known in the d case (related to ‘no-regret… CONTINUE READING
