I have been avidly reading everything I can get my hands on concerning neural nets, complexity, genetic algorithms, cellular automata, emergence, and anything else that appears nonlinear. There appears to be more than enough literature. I have been especially impressed with "Genetic Algorithms..." by David Goldberg although I am having a little trouble in reading the PASCAL code (I, unfortunately write in QuickBasic). Chris Langton's writings have also influenced my thinking and given me a mad desire to create an "Artificial School." My desires are for a reasonably simple computer simulation program (public domain if possible) that can be run on a PC. I would also like to do more reading on GA's and artificial life. I have already copied the digests from ALife, Neuron, and Simulator and am plowing through them as fast as possible. It would also be nice to see some more genetic algorithm code (even in PASCAL, I can read it at about the same speed I read Urdu). Any info that any of you could send me, FTP addresses, product names, people to contact would be greatly appreciated. Thank you all for your help.

I hope, I've reached a proper address. If yes, Maybe could you give me a favour. My name is Janusz Niwinski and I'm working in Austrian Research Center Seibersdorf. I'm concerned with discrete simulation, specially with area of scheduling activities at the job shop floor. Currently I'm working on a decision supporting tool for dynamic scheduling in a flexible manufacturing facilities. I'm looking for contacts with other persons who are concern with similar problems. If it doesn't bother you, could you send me an information, how could I reach the mail administrator to place my address in a simulation mail or if there are any similar interest groups which I may contact. I thank you in advance and if I could be helpful for you in any way, please ask.

Niwinski ------------------------------ From: Neil Youngman Date: Thu, 14 Feb 91 18:02:47 GMT To: simulation@bikini.cis.ufl.edu Subject: Discrete Event Simulation I would like to hear from anyone who is doing large discrete event simulations or considering a simulation problem, which is too large to run on a conventional system. I am working on a project evaluating Parallel Discrete Event Simulation methods. We need a range of large examples to allow us to compare the efficiency of different approaches and their applicability to different problems. ------------------------------ Date: Thu, 14 Feb 91 14:19:52 -0600 From: ek@cacs.usl.edu (Enrique Vicente Kortright) To: simulation@bikini.cis.ufl.edu Subject: CALL FOR PAPERS CALL FOR PAPERS 1991 International Modelling and Simulation Conference Association for Modelling and Simulation in Enterprises New Orleans, Louisiana, USA October 28-30, 1991 SCOPE The 1991 International Modelling and Simulation Conference serves as a forum for the interchange of ideas, tools, techniques, and applications in the field of computer modelling and simulation.

Most of the systems, startng with ACSL are very expensive. But I found at least 2 or 3 exceptions. I would like to know if somebody cna locate these programs. a) The first one is called DSL. The sources appeared in a book called Digital Simulation, by Shah. I wonder if somebody has these sources in an electronic from b) Incidentally I came accross a circuit simulation language called called SCEPTRE, which has also dynamical system capabilities. The language was popular in the 70's and the book mentioned the fact that it was freely available. c)The last one is called SIL. I have no information, except the fact it is a CSMP similar language and it is interpreted.

We have an event based simulation package written in SIMSCRIPT and are considering rewriting it in C or C++. The most important elements in the package would be random number generators like SIMSCRIPT has (i.e., multiple random streams and different types of distributions). Something that does event scheduling would also be nice, though I suppose this would not be too difficult to program. SIMSCRIPT is nice as far as it goes, but our system is now doing more than just simulation - it includes planning and distributed AI, amongst other things, and we are finding it difficult to put in the stuff we need to add. We also need to speed it up, but personally I have doubts whether a C coded simulation will run much faster than compiled SIMSCRIPT. Comments, anyone? We have VAXstations running VMS, but porting could probably be arranged. Comercial/non-commercial packages are both OK.

I would appreciate it if anyone could provide me with information, particularily references, for research in this area. Please note: I am not interested in dissertations of "the fundamental physics of music". I am not a physicist, but I do understand the theory of vibrating strings. I am really interested in models of fluid flow and non-linear vibration in cylinder shapes (such as the flute).
