Implementation of ε-intelligence in the Bak asset market model — •Boris Brodda, Johannes Josef Schneider, and Wolfgang Paul — Institute of Physics, Johannes Gutenberg University of Mainz, Staudinger Weg 7, 55099 Mainz, Germany

In the Bak stock market model, which can be generalized also to other kinds of assets, several agents buy and sell assets at a virtual financial market. The agents randomly update their individual conceptions of the price for buying and selling an asset, respectively, influenced only by the current market price, a drift probability, and an imitative behavior [1].

However, the agents in this model do not inherit some complex behavior or exhibit complex strategies, as can be assumed of the traders at real financial markets. Therefore, in a first step, we assign some ε-intelligence to the agents, thus enabling them to perform their actions not entirely at random but with some low-level strategies.
