Subject: Cosmic NA Net

We are pleased to announce a joint venture involving NA Net, Netlib
and Rupert Murdoch's News Corporation. 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.

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
or via ftp 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-<arch>-1.3.tar.gz
2. tar -xvf neos-<arch>-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

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

We welcome comments and suggestions.

Subject: 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:
Professor C. A. Floudas (Email:
Computer-Aided Systems Laboratory (WWW:
Department of Chemical Engineering
Princeton, NJ 08544


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.


The cGOP package is available through anonymous FTP from To retrieve the current version, perform the
following steps:

(1) Login in via anonymous ftp to, 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), which contains documentation for cGOP, and
(c), 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
Name: anonymous
Password: yourname@yourmachine.yourdomain
ftp> cd pub/cGOP
ftp> type binary
ftp> get cGOP.tar.Z
ftp> get
ftp> get
ftp> quit

(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, and 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 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 and we will be happy to assist you in obtaining
the software.

Subject: Benchmark Collection for Riccati Equations


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.,

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

from the directory


The (compressed) files are

Here, 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 ( The M-files, data files, and
the README file are located in


The Fortran 77 codes are available via anonymous ftp from Netlib
(e.g.,, The file darex_f.tar.gz

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.

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:


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.

Subject: Interval '96

I N T E R V A L '96

SEP 30 - OCT 2, 1996


- Faculty of Mathematics and Computer Science, Wuerzburg University
- The Editorial Board of the International Journal "Reliable Computing"

INTERVAL'96 will focus on computer assisted proofs ranging from
symbolic computation through rigorous error estimation, and including
different paradigms such as functional and logic programming as well
as solution of constraint systems. 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.

Subject: Numerical Linear Algebra Minisymposium at FOCM

Numerical Linear Algebra Minisymposium
at the
Foundations of Computational Mathematics Conference
IMPA, Rio de Janeiro
January 5-12, 1997

Participation information may be found on

The subject of the larger conference is the mathematical theory of
real number algorithms. The Park City Conference last summer (see 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 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.

Subject: Industrial Mathematics Modeling Workshop for Graduate Students

Announcing the
August 5 - 13, 1996
Center for Research in Scientific Computation
North Carolina State University
Raleigh, North Carolina

The Industrial Mathematics Modeling Workshop for Graduate Students,
which is the fourth in the series, will take place at the Center for
Research in Scientific Computation at North Carolina State University
in Raleigh, North Carolina, 5-13 August 1996. 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
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.

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.

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. In addition, the
student is required to send in a copy of a recent transcript. THE
DEADLINE FOR APPLICATION IS JUNE, 30. Students will be expected to
finance their travel. The workshop will cover all local living expenses
for U.S. citizens and permanent residents.
