At the risk of committing heresy on a NA-NET, I'd like to know whether there exists any general purpose "global optimization" software (of the genetic or simulated annealing variety?) that I can try out on this problem. Thanking you in advance, Sincerely Amit Bhaya NA.BHAYA@NA-NET.ORNL.GOV ------------------------------ From: Ulrich Ruede Date: Sat, 8 Aug 1992 17:28:39 +0200 Subject: Workshop on C++ for Scientific Computing SUMMARY Workshop on C++ for Scientific Computing On April 14th, at the Copper Mountain SIAM conference on iterative methods, a workshop was held to present C++ as a useful language for Scientific Computing. The workshop was organized by Dan Quinlan and included a panel of seven participants: Dinshaw Balsara, from Johns Hopkins University; Doug Clarkson, president of Dyad Software Corporation (developers of the M++ array class library); Carl Kesselman, from Caltech; James S. Peery, from Sandia National Laboratory; Daniel Quinlan, from University of Colorado at Denver; Allen C. Robinson, from Sandia National Laboratory; and Ulrich Ruede, from Technische Universitaet Muenchen. C++ as a language for scientific computing has recently been gaining increased attention. Besides providing the programming concepts of an advanced language it can be highly efficient, is widely available and is very portable. Its features make it almost ideally suited for the tasks in mathematical and scientific software development. The class concept and operator overloading make the language extensible so that user defined data structures can be handled the same way as built-in data types. Thus all the FORTRAN-90 array language functionality can be provided on the library level. Similarly, most standardization problems for numerical libraries in FORTRAN would be much easier in C++, because the abstraction mechanisms of C++ allow more natural interfaces that are not obscured by work-arounds for language deficiencies. A brief summary of the workshop is available by ftp from the mgnet server casper.cs.yale.edu in the directory mgnet/papers/Ruede.

The scope will be widened on this occasion to include other related areas of applied mathematics and scientific computation. It is also a celebration of the 60th birthday of John Butcher of the University of Auckland, who has taken a lifetime interest in the subjects of the conference. The conference is being organised by the Department of Mathematics and Statistics of the University of Auckland and the venue is within the University campus. Registration is requested as soon as possible. The registration fee is $NZ300 if paid by 15 September 1992 and $NZ350 if paid at a later date. Because of the need to make final arrangements in good time, it is recom- mended that all registrations be made by 31 October 1992. A lower registration fee will be charged to student participants. Further information is available on request. In particular, an electronic copy of an information brochure together with a registration form is available by e-mail. Included in this material is a call for papers.

E-mail: reuter@dhdibm1.bitnet SCOPE Advances in Computational Mathematics is an interdisciplinary journal of high quality, driven by the computational revolution and emphasising innovation, application and practicality. This journal will be of interest to a wide audience of mathematicians, scientists and engineers concerned with the development of mathematical principles and practical issues in computational mathematics. Publication areas include computational aspects of algebraic, differential and integral equations, statistics, optimization, approximation, spline functions and wavelet analysis. Submissions are especially encouraged in modern computing aspects such as parallel processing and symbolic computation and application areas such as neural networks and geometric modelling. All contributions should involve novel research. Expository papers are also welcomed provided they are informative, well-written and shed new light on existing knowledge. The journal will consider the publication of lengthy articles of quality and importance. From time to time special issues of the journal devoted to meetings or topics of particular interest to the readers will be published with the guidance of a guest editor. Ideas for such special issues can be communicated to the Editors-in-Chief. Software of accepted papers will be tested and be made available to readers. Short announcements, a problem section and letters to the Editor will also appear in the journal at regular intervals. Advances in Computational Mathematics will be published quarterly. CALL FOR PAPERS Authors are cordially invited to submit their manuscripts in triplicate to the Managing Editor or sent in duplicate to any member of the editorial board, together with one copy to the Managing Editor and a copy of the covering letter. All the manuscripts will be referred. The decision for publication will be communicated by the Managing Editor. After acceptance of their paper, authors who can should send a diskette with the TEX (or LATEX or AMS-TEX) source of their paper together with a hard copy of it and the letter of acceptance to the Managing Editor. For papers concerning software an ASCII diskette is needed. ------------------------------ End of NA Digest ************************** -------
