Notes on Barry B. Hughes'
International Futures Simulation (IFs)

Richard W. Chadwick

I structured this hypertext adaptation over the period 1991-1993, with Barry Hughes' encouragement; it's obsolescent since you can now download the latest IFs version which comes with extensive help. You can also get a brief overview of the model there, too.

What follows are variable and parameter definitions from IFS90 help screens with very minor format changes, originally to adapt them to Neil Larson's HyperRez program retrieval system. I did it for my international relations classes at the University of Hawaii. Most of what you'll find here now is present in the latest IFs for Windows, but you may find this a handy plain text reference on the Internet.
