We present detailed numerical results for a modified form of the so-called
Minority Game, which provides a simplified model of a competitive market. E
ach agent has a limited set of strategics, and competes to be in a minority
. An evolutionary rule for strategy modification is included to mimic simpl
e learning. The results can be understood by considering crowd formation wi
thin the population. (C) 2000 Elsevier Science B.V. All rights reserved.
