Similar to the ZIP strategy, the Roth-Erev (RE) strategy  is another adaptive trading strategy algorithm which adopts reinforcement learning. In the GjestadDickhaut (GD) strategy , traders first collect the market history from an order book and use it to estimate the transaction success probability distribution, and then calculate the optimal shout price to maximize the expected profit. All of the above work focused on traders trading a single good in a single market. If we extend this to trading a single good over multiple markets, some natural examples are financial markets and auction services.
P. Wellman 1. feasible: the set of goods allocated to buyers is contained in the set of goods supplied by sellers, and the net payments are nonnegative, and 2. acceptable: individual payments meet the reserve price constraints expressed in the bids of buyers and sellers. We assume agents have quasilinear preferences over alternative allocation and payment outcomes. Buyer i has quasilinear utility function ui (g, p) = vi (g)+ p, where valuation vi defines the net change in buyer utility when supplied with a given allocation, and p denotes the net payments made to the buyer.
The class of complement-free buyer valuations contains all valuations which are never superadditive over configurations. Definition 1. A buyer valuation is complement-free (CF) if for any ga and gb , v(ga ) + v(gb ) ≥ v(ga ∪ gb ). A seller valuation (cost function) is complement-free it is not subadditive over configurations, that is, the direction of the above inequality is reversed for sellers. It is known that no polynomial clearing algorithm can guarantee better than a 2approximation for the general class CF .
