Effective immediately, it will be possible to down load software and other material from Netlib using the various international digital TV satellite systems operated by Murdoch's companies, including the "Sky" satellite in Europe and the "Star" satellite in Asia. Murdoch's North American satellite system will not be operational until the fall; in the interim, Netlib will be carried by cable's Home Shopping Network. An inexpensive video sensor is now available at many electronic and computer stores. It plugs into a SCSI port on most computers, receives bar-code video signals from the TV set and translates them into source and object code files on the computer. A Java applet is available which will search the computer's entire file system, find any programs which reference the Netlib routines and finish the job of making complete applications. The joint venture also involves NA Net mail and the NA Digest. An Internet search engine is already periodically checking the login and password files of all computers connected to the Net and monitoring the location and usage of all NA Net members. After a few months, a principal components algorithm (employing the singular value decomposition) will be able to anticipate individual member's travel plans and insure that NA Net mail and the NA Digest will rearch them any place in the world. This should work well for everybody except Gene Golub, who travels so much that none of us can keep track of him. We are all excited by this new venture, which demonstrates, yet again, that NA Net will use any technology we can get our hands on. -- Cleve Moler Jack Dongarra Eric Grosse ------------------------------ From: Jorge More' Date: Tue, 26 Mar 1996 10:27:14 -0600 Subject: Submission Tool for Optimization Problems The NEOS Submission Tool for Optimization Problems We have developed the NEOS Submission tool, a high speed, socket-based interface for UNIX workstations that provides easy access to all the optimization servers available with the Network-Enabled Optimization System (NEOS) server. The current version (1.3) of the tool only assumes that you have Perl installed. Download the tool via the Web http://www.mcs.anl.gov/home/otc/Server/subtool.html or via ftp ftp.mcs.anl.gov in pub/neos/submission_tool You need to download the package for your architecture. We currently support sun4, rs6000, iris4d, HP, BSD, and linux. If you have Tcl/Tk installed, you can download the architecture-independent "no-wish" package. Installation is simple: 1. gzip -d neos--1.3.tar.gz 2. tar -xvf neos--1.3.tar 3. cd neos-submission-1.3 4. execute "perl install" to generate the perl scripts The executable neos-submit can be moved to any directory in your path. Execution of "neos-submit" launches the NEOS submission tool. We have included sample data for two areas: -Unconstrained Minimization -Linear Programming Select one of these areas under "Software Library", and click on "submission form" in the lower left hand corner of the submission tool to obtain a submission form. Clicking on "submit" sends the sample problem to the NEOS Server. Fortran and C submissions are provided for the Unconstrained Minimization area, and an MPS file for the Linear Programming area. The NEOS server uses state-of-the-art algorithms to solve optimization problems automatically with minimal input from the user. For more information on the NEOS Server see http://www.mcs.anl.gov/home/otc/Server The NEOS Server is operated by the Optimization Technology Center, a joint venture of Argonne National Laboratory and Northwestern University. For more information on the OTC see http://www.mcs.anl.gov/home/otc We welcome comments and suggestions.

Brualdi Hans Schneider Editors-in-Chief of LAA 26 March 1996 ------------------------------ From: Brynjulf Owren Date: Wed, 27 Mar 1996 09:50:57 +0100 Subject: SYNODE Home Page Dear Colleagues, In connection with the project SYNODE on geometric integration, Hamiltonian integration methods and methods for DAE problems we have created a WWW page where we hope to publish material of interest to many NA-netters. For the moment LaTeX bib-files with references for Hamiltonian and geometric integration are available, and we plan to add more information as the project goes on. We are also interested in input from the NA-net readers, e.g. pointers to the literature and to other WWW pages that we are permitted to reference. Any suggestions are welcome and should be sent by email to synode@imf.unit.no. The URL of the home page is http://www.imf.unit.no/num/synode/ With regards from the SYNODE group Brynjulf Owren ------------------------------ From: Vishy Visweswaran Date: Wed, 27 Mar 1996 14:35:47 -0500 (EST) Subject: New Package for Global Optimization cGOP -- A NEW PACKAGE FOR GLOBAL OPTIMIZATION We are pleased to announce the availability of cGOP, a new software package for solving structured global optimization problems. A description of the package follows, along with instructions on how to retrieve, install and use the package. Dr. V. Visweswaran (Email: vishy@titan.princeton.edu) Professor C. A. Floudas (Email: floudas@titan.princeton.edu) Computer-Aided Systems Laboratory (WWW: http://titan.princeton.edu) Department of Chemical Engineering Princeton, NJ 08544 DESCRIPTION OF THE PACKAGE: cGOP is a package for rigorously solving nonconvex optimization problems to epsilon-global optimality. The package implements the GOP algorithm (Floudas and Visweswaran, 1993) which is a primal-dual decomposition algorithm applicable to general constrained biconvex problems, using a set of C subroutines to solve these problems using decomposition and branch-and-bound techniques. It also incorporates several improvements made to the original GOP algorithm to reduce the computational complexity (Visweswaran and Floudas, 1993) as well as new formulations that permit implicit solutions of some of the subproblems encountered during the algorithmic steps (Visweswaran and Floudas, 1996). The algorithms use local optimization solvers (currently MINOS 5.4 and CPLEX 3.0) to solve linear, mixed-integer linear and convex subproblems. This version of the cGOP package is a beta-test version, and can be used to solve problems with linear constraints. Problems can be specified using data files written in a high-level parsed language that permits their solution without re-compilation, and also using fixed-format data files. In addition, the package can be used via calls to C subroutines. cGOP has been in use at the Computer-Aided Systems Laboratory in Princeton University for the last two years, and has been used to solve problems involving several hundred variables and constraints. Currently, versions are available for Hewlett-Packard, Silicon Graphics and IBM RS6000 machine architectures. This is a beta-test version of the software, and is being released for use by academic researchers. A full version with the ability to solve nonlinearly constrained problems will be made available in the future. Commercial sites wishing to use this product should contact one of the authors directly. HOW TO OBTAIN THE SOFTWARE: The cGOP package is available through anonymous FTP from titan.princeton.edu. To retrieve the current version, perform the following steps: (1) Login in via anonymous ftp to titan.princeton.edu, using the user name "anonymous" and giving your email address as the password. The package is located in "pub/cGOP", and has three components - (a) cGOP.tar.Z, which contains the main libraries and examples, (b) cGOPdoc.ps.Z, which contains documentation for cGOP, and (c) cparsedoc.ps.Z, documentation for cparse, a high level parser that can be used to enter the problems for cGOP in an easy format. Make sure to set file type to binary before retrieving the files. Below, we show a sample session of using anonymous ftp: unix> ftp titan.princeton.edu Name: anonymous Password: yourname@yourmachine.yourdomain ftp> cd pub/cGOP ftp> type binary ftp> get cGOP.tar.Z ftp> get cGOPdoc.ps.Z ftp> get cparsedoc.ps.Z ftp> quit unix> (2) Select a directory where you want to store the distribution. Go to that directory, then: prompt> uncompress cGOP.tar.Z prompt> tar -xf cGOP.tar This will create a subdirectory called "Gop" under the current directory, and put the distribution there. (3) Uncompress and print out the manuals, cGOPdoc.ps and cparsedoc.ps. These contain full instructions for installing and using cGOP and the parser. (4) Look at the directories "cparse", "examples" and "callable". These contain example files that show how cGOP can be used through data files or using calls to C subroutines. (5) If you do retrieve the package, please send us an e-mail at cgop@titan.princeton.edu with a brief description of the machine you intend to run it on. This will help us to keep you informed of updates, bug fixes etc. If you have any difficulty getting the files, please send us an e-mail at cgop@titan.princeton.edu and we will be happy to assist you in obtaining the software. ------------------------------ From: Steve Morgan Date: Thu, 28 Mar 1996 14:00:15 -0500 (EST) Subject: Reading MPS Files into MATLAB Would there be a program already written somewhere that can read MPS-format files into MATLAB? -Steve Steve Morgan http://www.afn.org/~hypnotic/ hypnotic@afn.org ------------------------------ From: Peter Benner Date: Fri, 29 Mar 96 11:10:34 MEZ Subject: Benchmark Collection for Riccati Equations FIRST VERSION OF DAREX AVAILABLE DAREX is a collection of benchmark examples for the numerical solution of discrete-time algebraic Riccati equations (DARE) of the form T T T -1 T T 0 = A X A - X - (A X B + S) (R + B X B) (B X A + S ) + Q where A, Q, X are n-by-n matrices, B, S are n-by-m matrices, and R is an m-by-m matrix. Here, Q, R are symmetric and X is the desired symmetric solution matrix. The matrix Q can be given in factored form as it often occurs in control theory, i.e., T Q = C Q0 C. This collection may serve for testing purposes in the construction of new numerical methods, but may also be used as a reference set for the comparison of methods. The examples can be generated via a Fortran 77 subroutine or a MATLAB function. A postscript version of a preprint describing the benchmark collection as well as the software is available by anonymous FTP at ftp.tu-chemnitz.de from the directory /pub/Local/mathematik/Benner The (compressed) files are blm2.ps.Z darex_f.tar.Z darex_m.tar.Z Here, blm2.ps.Z is a compressed postscript version of the abovementioned preprint and the tar files darex_f.tar, darex_m.tar, respectively, contain directories with the subroutines, functions, and data files necessary to generate the benchmark examples. Both directories also contain introductory README files. The MATLAB codes are also available via anonymous ftp from the MathWorks ftp site (ftp.mathworks.com). The M-files, data files, and the README file are located in pub/contrib/control/darex The Fortran 77 codes are available via anonymous ftp from Netlib (e.g., netlib.att.com, elib.zib-berlin.de). The file darex_f.tar.gz can be found in the directory netlib/control Since this is an on-going project, we will greatly appreciate further contributions of examples concerning the abovementioned DARE as well as continuous-time and generalized AREs.

Mitrinovic International Memorial Conference D.S. Mitrinovic June 20-22, 1996 Nis, Serbia, Yugoslavia - Second Announcement - The "International Memorial Conference D.S. Mitrinovic" will be held in Nis, Serbia, Yugoslavia from June 20-22, 1996. Because of great interest and large number of participants, the Organizing Committee made a decision to transfer the place of the conference from Belgrade (as it has been announced in the First Announcement) to Nis, where exists better conditions for the conference work. Also, the duration of the conference is enhanced for one more day. The conference will be held on the Faculty of Electronic Engineering, Beogradska 14, 18000 Nis. The accepted papers will be published in three volumes dedicated to Professor Mitrinovic. The titles of volumes will be as follows: 1) RECENT PROGRESS IN INEQUALITIES; 2) ADVANCES IN MATHEMATICAL ANALYSIS; 3) TOPICS IN MATHEMATICS WITH APPLICATIONS. The approximate number of pages per volume will be 400. The appearance of the first volume is expected in ahead of the conference, whereas the other two will appear later. All volumes will be comprised of survey and contribution papers. Survey papers, due to their length, content and scientific value may be considered as a book chapters, and thereby, could be of great interest to the wide range of mathematicians. Also, the authors are well-known and have a significant contributions in the relevant topics. The details concerning of the accommodations and travel possibilities will be sent to the participants by ordinary mail until April 15, 1996. The Organizing Committee made the decision that all local expenses due to accommodation will be covered to all the invited speakers. Also, all possibly interested mathematicians who wish to attend the conference are welcomed and could send their applications to the Organizing Committee until April 30, 1996.

The traditional interval approach will appear as one important aspect common to most of the approaches. Although papers may be restricted to one of these topics, we especially encourage the submission of reports on combination of several approaches. Interval constraints, e.g., provides an efficient model for computing reliable bounds for numerical constraint systems. It opens a way of application of interval arithmetic for commercial rather than scientific problems. The combination of control theory and game theory together with interval or standard numerical methods to obtain reliable inclusions may be quoted as another example of interesting applications. The following topics will be considered: interval mathematics, hardware and software for interval and computer-algebraic methods, SC-languages, logic constraint programming, interval modelling, interval constraints, computer aided proofs in analysis, interval algorithms in control theory, organization of symbolic-numeric interfaces, programming environments for scientific computing, and applications in various fields of science and engineering as well as commercial issues. For each talk or poster a copy of an extended abstract of maximum 2 pages is requested for selection purposes. Please use our LaTeX frame available via WWW. The deadline will be May 1 1996. Full papers are due at the conference. Electronic submission is strongly recommended. Please use the email address below. A collection of extended abstracts will be printed before the conference. Refereed proceedings including full versions of selected papers will be published after the conference as two volumes of the International Journal Reliable Computing.

The Park City Conference last summer (see http://www.damtp.cam.ac.uk/DAMTP/user/na/FoCM/FoCM.html) with its emphasis on the mathematical side of numerical analysis was considered so popular that the organizers have decided to try to hold an annual or perhaps biennial meeting. The interplay between numerical linear algebra and the other eight or nine areas was very exciting, and we fully expect the same excitement level at this conference. Prospective participants are encouraged to contact directly workshop organizers (Jim Demmel and Alan Edelman) if they intend to submit a talk. The ideal method is to fill out the web form, but email to rio@math.mit.edu is also acceptable. Papers may be submitted and talks may be proposed. Following the general conference structure, the organizers of the workshop will determine to reject, accept for a talk only or accept for a talk and publication. Those submissions ready for journal publication, including especially any excellent plenary talks of a survey nature, may be published in the Journal of Complexity. These papers will be eligible for the Best Paper Award of the Journal of Complexity for 1996. The award is $3000. A volume of extended abstracts will be published by IMPA. The Instituto Mathematica Pura e Applicada (IMPA) is spectacularly located on the edge of a tropical forest in Rio de Janeiro, overlooking the Lagoa. It is in a beautiful building, with excellent library, world-class mathematics, and has a great deal of experience in organizing meetings. See the conference home page for further details including the nominal registration fee. To submit a talk for the Numerical Linear Algebra Minisymposium please fill out the form on http://www-math.mit.edu/~rio/rio.html (ideal method) or contact the organizers at rio@math.mit.edu. ------------------------------ From: IMACS Administration Date: Wed, 27 Mar 1996 11:43:13 -0500 Subject: IMACS Conference on Numerical Solution of ODEs IMACS- NUMDIFF 8 Under the Sponsorship of IMACS, the Department of Mathematics and Computer Science of the Martin-Luther-University/ Halle-Wittenberg and the CWI -Amsterdam organize...

This workshop is being held annually, the previous highly successful meetings was held at the Claremont College in 1993 and 1994, and at North Carolina State University last year. In line with the previous workshops the goals of this workshop are: * to expose 30 graduate students in mathematics and statistics to the challenging and exciting real-world problems from industry and government laboratories; * to introduce students to the team approach to problem solving. Funding for this workshop has been requested with the National Security Agency (NSA). Additional support is anticipated from the Center for Research in Scientific Computation (CRSC) and the Department of Mathematics at NCSU. FORMAT In the workshop the students will be divided into six teams to work on "industrial mathematics" problems presented by experienced applied mathematicians. These problems are challenging, real-world problems from industry or applied science and require fresh, new insight for their formulation and solution. The problem presenters, primarily from industry and government laboratories, are being recruited and their names will be announced subsequently. We are expecting one problem presenter from the NSA. Other scientists will whom we have discussed possible participation include: scientists from Lord Corp., Micro Craft Technologies, Aerospace Corporation, and Chemical Industry Institute of Toxicology. APPLICATION PROCEDURE Graduate students in mathematics, applied mathematics, statistics or operations research can be nominated for this program by a faculty member by sending a letter of recommendation.
