- Cinc isn't actually CA, though it should be of interest to those who are
- interested in the field. Cinc is the NeXT implementation of "Creatures", a
- system which attempts to address ome of the problems which arise from the
- spacial nature of CA without loosing the features we all know and love. The
- software may be ftp'd from sonata.cc.purdue.edu
- pub/next/submissions/CincDist.tar.Z. Papers may be obtained from
- shiraz.ohm.york.ac.uk. I've included part of the README file below.
-
- The Creatures project is currently looking for beta test sites, so feedback is
- welcome, and limited technical support is available.

- Cinc - The NeXT Creatures Simulator
-
- Cinc is an implementation of the Creatures processing model for the NeXT.
- Creatures attempts to retain many of the attractive features of CA while
- allowing dynamic systems to be studied more easily. This is done by describing
- the active elements of a system, rather than the space in which they live.
-
- Consider a simple model of road traffic - on a CA we must describe roads as
- either holding cars or not, then passing cars between them. The negotiation to
- support this rappidly swamps and cnsideration of what the CARS are doing. With
- Creatures we describe the cars - after all everyone knows what a car does!
-
- The net result of this is a simulation environment that allows emergent
- behaviour to be studied easily, and models to be built rapidly without a great
- deal of programming experience - just describe what all the bits do, and what
- they do when they meet.
-
- Once written and debugged on a NeXT, the same (or at least VERY similar) code
- may be run on a CM-2(pretty fast) or a MasPar(very fast). This allows you to
- test models when very large numbers of elements are active.
