Introduction to the World of Empirical Modelling

Thank you for your interest in Empirical Modelling. This document will give you some idea about how to set up and run some of our demonstration programs.

Most of the work relating to Empirical Modelling is to be found under the directory :
/dcs/acad/wmb/public
This directory contains the following files and directories :

• README - introductory material in plain text, subsumed by this document
• bin - executable files and shell scripts
• bin/sun4 - sun 4 executable files
• lib - various library files for the systems, mainly written in EDEN
• demos - demonstration programs
• doc - memos for the definitive systems, mostly outdated + eden handbook (PC Word 6 format) + sy.thesis + samia.thesis
• projects - sources of various projects, which includes:
  • notations - definitive notations
  • tools - editors, translators, demo maker, etc
  • games - games written using definitive notations
  • simulations - simulations written using definitive notations
  • misc - other scripts written using definitive notations
• ProjectList - a one line description of all the definitive projects
• Papers - some published papers
• TECH.LIB - technique example library + FAQ
• utils - utilities (not directly to do with Empirical Modelling)
• TKEDEN.usage - records of the tkeden usage
• .TKEDEN - the current tkeden usage record (can only be read by the defnot group)

In order to make this public directory portable, some of the executable files and shell scripts are referring to an environment variable PUBLIC which should be the path name of the directory in which this file resides. So please set it now!

If you are using csh or tcsh, type:

setenv PUBLIC /dcs/acad/wmb/public
setenv PATH ${PATH}:${PUBLIC}/bin

if you are using sh or bash, type:

PUBLIC=/dcs/acad/wmb/public
export PUBLIC
PATH=$PATH:$PUBLIC/bin
export PATH

How to run the demos :

1. Set up the PUBLIC variable, procedure as above,
2. Go to the demos directory,
3. Normally, if the demo is a single file, you can execute by tkeden filename ,
4. If it is a directory, go to that directory and run,
5. See the README file in that directory for further/alternative instruction.

• Note that for some demos, resizing of the screen is needed.
