Assn. f. Art. Intell.) 1988 p. 280). You may want to look at the new collection of papersw in qualitative physics, just published by Morgan Kaufmann, edited by Dan Weld and Johan deKleer.

There is one at JPL, I believe that David Jefferson (jefferso@cs.ucla.edu) will be able to tell whether it is public domain. There is an implementation at the University of Calgary, I suppose that Brian Unger or John Cleary will be able to tell what is the status of this one (ihnp4!alberta!calgary!lomow is Greg Lomow's address there and I believe that Brian's is "unger" replacing "lomow" and John's is "cleary" replacing....). There is also a simulation that I wrote in simula which simulates the distributed system and on top of that implemented time warp with lazy cancellation, at this point I have only the source code on paper, I have no idea as to where the original tape is.... I am sure that there are additional implementations that I do not know about, but the above references can help find one in an environment similar enough to the one you have. Also, David Jefferson and the people from Calgary will have by now a fair list of publications and dissertations on the topic.

I could not obtain anything on how to obtain BIFPACK; however, I'll include here what I know about AUTO: -paul fishwick ---------------------------------------------------- From: Tom Fairgrieve <tff@na.toronto.edu> To: fishwick@fish.cis.ufl.edu Subject: re: Bifurcation-Related Software Date: Thu, 24 Aug 89 15:49:51 EDT The AUTO package was written by Eusebius Doedel and is available from: Applied Mathematics 217-50 California Institute of Technology, Pasadena, CA. 91125 I believe the cost is $200.00. You should also ask for the technical report: Software for Continuation and Bifurcation Problems in Ordinary Differential Equations. Prof. Doedel is now at a University in Montreal. His address is Computer Science Department Concordia University 1455 de Maisonneuve Blvd. W. Montreal, Quebec CANADA I know that AUTO is being used by many people. What sort of problems are you interested in solving?

It can handle discrete dynamical systems too. It comes with a graphics package which helps when trying to interpret all of the numbers it produces. The package does things like: plot a bifurcation diagram, plot the solution to the ode for a given point on the diagram. It's a very nice piece of software.

I have yet to order the (magnetic) tape from them. You can order AUTO from Ms. S.K. Shull Applied Mathematics, 217-50 California Inst. of Technology Pasadena CA, 91125 Ph: (818) 256-4560 I know of another bifurcation package called BIFD (and BIFDD) that is available on floppys from Dr. Brian Hassard at SUNY Buffalo. I think he is in Applied Maths. I would appreciate any information on BIFPACK. I've never heard of this.

If you know of or ran across a book or article that you think is interesting, I would appreciate if you send me its reference. many thankx.
