w2mind.computing.dcu.ie -> tyrrell's simulated environment

The Simulated Environment was build as part of the PhD research of Toby Tyrrell at the University of Edinburgh in 1993. The intention was to model a complex environment inhabited by a creature with multiple conflicting goals. Tyrrell then implemented several action selection mechanisms, each of which were separately plugged into the creature in order to allow it to choose between the thirty five low level actions available to it. Using the results Tyrrell was able to assess each of the action selection mechanisms and design a new mechanism that out performed all those tested.

A new implementation of the Simulated Environment is available here as a World-Wide-Mind service. This re-implementation in Java provides precisely the same functionality as was available in Tyrrell's implementation in C. 

The remainder of this section is divided into the following sub-sections:

• Detailed explanation of Tyrrell's environment

• Definition of state and action

• Implementation of Drives mind for action selection

• Implementation of Edmund mind for action selection

• You can view a log of minds deployed on w2mind.computing.dcu.ie here.

• Scoreboard of best scoring minds (a manipulatable list of scores is here (not updated after every run), the SOML version of the score board is available here).

• A historical record of scores achieved in 2003 and early 2004 is available in SOML and HTML, and a more recent scoreboard using some of the submissions from 2005 (SOML, HTML, manipulatable HTML).
