abstract = "In this paper first a precise mathematical model is
obtained for four competing or cooperating companies'
stock prices and then the optimal buy/sell signals are
ascertained for five different agents which are trading
in a virtual market and are trying to maximize their
wealth over one trading year period. The model is so
that gives a good prediction of the next 30th day stock
prices. The companies used in this modeling are all
chosen from Boston Stock Market. Genetic Programming
(GP) is used to produce the predictive mathematical
model. The interaction among companies and the effect
imposed by each of five agents on future stock prices
are also considered in our modeling. Namely, we have
chosen eight companies in order that there is some kind
of interrelation among them. Comparison of the GP
models with Artificial Neural Networks (ANN) and
Neuro-Fuzzy Networks (trained by the LoLiMoT algorithm)
shows the superior potential of GP in prediction. Using
these models; five players, each with a specific
strategy and all with one common goal (wealth
maximization), start to trade in a virtual market. We
have also relaxed the short-sales constraint in our
work. Each of the agents has a different objective
function and all are going to maximize themselves. We
have used Particle Swarm Optimization (PSO) as an
evolutionary optimization method for wealth
maximization.",
