<h1>A Note on the Abstract Definitive Machine</h1>

<p> The Abstract Definitive Machine (ADM) was designed by Meurig
Beynon, Mike Slade and Edward Yung in 1988.  It was developed in
collaboration with Mark Norris at British Telecom as part of an
investigation into animation tools based on LSD, an agent-oriented
specification language.  The first implementation was due to Slade.
Later Simon Yung developed a translator from ADM to <a
href="/modelling/other/eden/index.html">EDEN</a>.  This document brief
describes the basic principle of Abstract Definitive Machine, the
principal features of <code>am</code>, Mike Slade's implementation of
the Abstract Definitive Machine, and <code>adm</code>, Simon Yung's
ADM to EDEN translator.  </p>
