Anda Date: Wed, 24 Oct 90 3:10:09 CDT Subject: Fast Rotation Scale Problems We have developed a fast plane rotation algorithm which we believe dynamically dampens scaling growth. Our results on random matrices are good. However, we want to also test our algorithm on matrices known to cause gross scaling growth, i.e., a significant proportion of the rotation angle tangent magnitudes are "near" one. If you know of such matrices (and the algorithm applied to it, e.g. SVD, EVD, etc.) please reply to either anda@cs.umn.edu or hpark@cs.umn.edu. Thank you. Andrew A. Anda Haesun Park ------------------------------ From: Nicholas Redding Date: 26 Oct 90 05:26:47 GMT Subject: Non-smooth Optimization I am looking for code for two nonsmooth optimization problems in my PhD thesis: 1. the minimum of a piece-wise linear convex function, and 2. a local minimum of a piece-wise continuous nonconvex function. I have read of the Fortran-codes M1FC1 and M2FC1 by Lemarechal employing the epsilon-steepest descent algorithm, but have been unable to track this down. I have already checked the netlib archive but without success. Code in C or Fortran for any algorithm would great. My thesis must be submitted in a few months, so I am under a huge deadline. Any help on this would be greatly appreciated.

The two major themes of the meeting are nonlinear dynamics and chaos and numerical modelling of transport but contributed papers are welcome from all areas of applied methematics. The Westin Hotel is adjacent to the Rideau canal and the conference center featured in the Meech Lake meetings. Parliament Hill, the National Art Center, museums, embassies and shopping districts are within easy walking distance. Room rates are $129 single and $149 double. Hotel reservations should be made directly with the Westin Hotel, 11 Colonel By Drive, Ottawa, K1N 9H4, ph: (613) 560-7000, fax: (613) 234-5396. A limited amount of cheaper accomodation is available at the University of Ottawa, five minutes walk from the hotel. Dr. Benoit Mandelbrot has tentatively agreed to present the keynote talk on fractals. Symposium on Numerical Modelling of Transport Phenomena: Coordinators: R.B. Simpson (Waterloo) and R.
