abstract = "In this paper, we propose a new architecture to study
artificial stock markets. This architecture rests on a
mechanism called 'school' which is a procedure to map
the phenotype to the genotype or, in plain English, to
uncover the secret of success. We propose an
agent-based model of school, and consider school as an
evolving population driven by single-population GP
(SGP). The architecture also takes into consideration
traders' search behaviour. By simulated annealing,
traders' search density can be connected to
psychological factors, such as peer pressure or
economic factors such as the standard of living. This
market architecture was then implemented in a standard
artificial stock market. Our econometric study of the
resultant artificial time series evidences that the
return series is independently and identically
distributed (iid), and hence supports the efficient
market hypothesis (EMH). What is interesting though is
that this lid series was generated by 'traders' who do
not believe in the EMH at all. In fact, our study
indicates that many of our traders were able to find
useful signals quite often from business school, even
though these signals were short-lived",
