New Navigation Experiment

[Christian J Lebiere]

Many of you requested during the workshop more examples of how to
survive and strive without the features of ACT-R 2.0 that are not
supported in ACT-R 3.0, including list values and patttern matching and
instantiation-specific production evaluation.  A new version of the
navigation model that appeared in chapter 5 of Rules of the Mind (and
with the companion disk), which made heavy use of those features, is now
available on the ACT-R web site at:

ftp://ftp.andrew.cmu.edu/pub/act-r/ftp/models/Navigation/

This directory contains the following text files and directory:

* a methodology file which explains the general methodology
  behind the transformation
* a README file which explains how to run the model
* an analogmaps file which contains the new model
* a loadmaps.lisp file which performs the low-level tasks
  such as reading the map files
* a map_files directory which contains the problem maps

and also:

* navsim.sea.hqx, a binhexed self-extracting archive which contains
  all of the above, plus PICT files of the maps: mac users should
  download this archive instead of the individual files.

Feel free to send me any feedback that you may have,

Christian
