Package: SCL v0.05.01
Author:  Barry McMullin <mcmullin@eeng.dcu.ie>
Date:    8th May 1997.

This is the README file for the SCL v0.05.01 source
distribution.

Documentation for SCL (v0.04) is available in Working
Paper 97-01-002 of the Santa Fe Institute, at URL:

 http://www.santafe.edu/sfi/publications/
   Working-Papers/97-01-002/

This is also mirrored at:

SCL v0.05 differs in only minor ways from version
v0.04:

  o Some minor changes were made to ensure that
    SCL would build successfully against the
    public, v1.0, release of Swarm.

  o The color scheme of the World Display was 
    changed (to support better rendering of 
    screen shots in monochrome hardcopy).

  o A dedicated random number generator and utilities
    is now used in preference to that provided with
    Swarm.  This is to ensure repeatability of
    results regardless of changes in the distributed
    Swarm random library.

SCL v0.05 was used to produce the scientific data
discussed in Working Paper 97-02-012 of the Santa Fe
Institute, available at URL:

 http://www.santafe.edu/sfi/publications/
   Working-Papers/97-02-012/

The data file archive referred to in that paper is
available as:

A revised version of this paper will be presented at
ECAL '97, the Fourth European Conference on Artificial
Life, Brighton UK, July 28-31 1997. The final version
of the paper is available at:

SCL v0.05.01 is a minor revision of SCL, to render it
compatible with Swarm version 1.0.2 (and later?).  The
major change is to remove any "manual" dropping of
probeDisplay's when the probed object is dropped (as
this conflicts with the *automatic* probeDisplay
dropping mechanism introduced with Swarm v1.0.1).
v0.05.01 should continue to exactly reproduce the
scientific results described in the paper cited above.
