In 1996 Axtell and Epstein published a book on artificial societies,
Sugarscape. The principles
of the models presented in the book are exactly those which led to the
development of Cormas : a spatial context and agents able to perceive,
move, transform their local environment and communicate. Thus this book
is an excellent basis to practice Cormas.
Five cases of the Epstein and Axtell book have been implemented and can
be dowloaded and installed on Cormas:
- Simple simulation, agents perceive and move to the best places.
- Renewable resource, agents consume the resource. The resource is renewable.
- Cultural evolution, agents have a tag which evolves, depending on
the meetings with other agents.
- Friendship, the agents meet and compare their tag. Each agent keeps
in memory the five agents whose tag is similar to his own tag (the animation).
- Trade, agents exchange sugar and spice. Local prices are defined for
