in the former Soviet Union, has been awarded the 1998
Kyrgyzstani Science and Technique State Prize.

This prize was awarded jointly to him and to A. A. Borubaev,
the President of Kyrgyz State National University, for their work
on "Developing of theory of topological spaces and its applications
by analytical and computer methods"; this includes Pankov's work
on validating computations in constructive metrical spaces and
computer motion in abstract topological spaces.

Subject: Need Help With SPLP Under g77

I am trying to package the sparse linear programming subroutine SPLP,
from the SLATEC library at netlib, for Debian Linux. I started with
the collection of code returned by "echo send splp from slatec | mail
netlib@netlib.bell-labs.com", uncommented the lines in src/i1mach.f
and src/r1mach.f relevant to the IBM PC, and compiled with the GNU
FORTRAN compiler, g77. Unfortunately, it declares all problems,
including the example in the source code, to be infeasible.

This program has been in use long enough (written in '81, last revised
in '93) that I am more inclined to suspect the compiler than the code.
I have experimented with compiler options (like -fonetrip to force DO
loops to be executed at least once) to no avail.

If anyone else has SPLP running under g77, and can give me some
pointers, I would be grateful.

Subject: New Book on Numerical Methods for Differential Equations

We would like to announce the book

SOLVING DIFFERENTIAL PROBLEMS BY MULTISTEP
INITIAL AND BOUNDARY VALUE METHODS

Luigi Brugnano and Donato Trigiante

Gordon and Breach Science Publishers, Amsterdam, 1998
418+xv pages, ISBN: 90-5699-107-8

The book deals with multistep methods for the numerical solution of
differential problems, both in the classical approach as initial value
methods and in the more recent approach as boundary value methods (BVMs).
The book is structured in three parts: the first part is devoted to the
essential mathematical tools; the second part concerns special families
of methods and their applicability to different kinds of problems;
finally, the third part deals with the implementation of the methods.
The book is appropriate for both undergraduate and graduate students with
a computational focus as well as for researchers in the field of numerical
methods for differential problems. The large number of examples also makes
the book appealing for engineers and those interested in applications.
A code based on BVMs can be found at
http://www.dm.uniba.it/mazzia/ode/readme.html

Contents

Part I : 1. Differential Equations
2. Linear Difference Equations with Constant Coefficients
3. Polynomials and Toeplitz Matrices
4. Numerical Methods for Initial Value Problems

Subject: New Section for Optimization Methods and Software

We are happy to announce a new section "Optimization Software" for our
journal "Optimization Methods and Software" (OMS). The section will be
edited by Tamas Terlaky.

The objectives of the new section are: to facilitate high level
software developments; to inform the optimization community about these
new developments; to make codes available to the optimization
community, and, to develop new ideas and new optimization software
tools. The software section of OMS will publish papers that
scientifically document novel programs and software packages
appropriate to solving optimization problems, or that describe
components in more complex software.

Each paper will be refereed to ensure: novelty, quality of
presentation, availability of software and potential to meet the needs
of the optimization community. The software section will publish papers
in the following three categories: primary papers of 10-15 pages,
which describe a class of problems, the methodology to solve such
problems and document the implantation and the power of the authors
software package; survey papers of 15-20 pages which survey and
evaluate the available software packages for a class of optimization
problems, and, short communications of 5-10 pages, which document
specific improvements in methodology or implantation technology of an
important algorithmic element of optimization software.

In addition to the standards as title, authors names and address
(including e-mail), abstracts and keywords, each paper should include a
clear definition of the problem class, exploring methodology and
implementation documentation, test set definition and evaluation,
relevant literature, and, where appropriate, information on how to
obtain the software and whether it is public domain or
(semi)commercial.

Software that is related to papers published in the software section of
OMS and made publicly available by the authors will be included in the
OMS collection of optimization software. Upon agreement, this software
will be published on the OMS-CD together with the written paper.

Papers and software for the OMS software section, preferably based on
Windows PC, HP, Sun UNIX or LINUX standards, should be submitted
directly to the software editor to the following address:

Subject: Workshop on Parallel Symbolic Computation

Workshop on Parallel Symbolic Computation
October 1-3, 1998
Program Schedule

We are organizing a workshop on parallel symbolic computation, to
be held October 1-3 at the Mathematical Science Research Institute,
which is near the campus of the University of California, Berkeley,
CA, USA. The workshop will involve approximately 50 mathematicians,
computer scientists and scientific users of symbolic computing
tools. We will explore the state of the art in symbolic computing,
including algorithms and computer techniques, with an emphasis on
parallel, high performance computer systems. The workshop is supported
by MSRI and NERSC (www.nersc.gov).

For up-to-date program information, as well as a complete list of
other workshops and conferences at MSRI, see MSRI's website,

Daniel R Grayson University of Illinois, Urbana-Champaign; Urbana, IL, USA
Alyson Reeves Center for Computing Sciences; Bowie, MD, USA
Nobuki Takayama Kobe University; Kobe, Japan

Scientific Content:

This workshop is inspired by the rapidly increasing requirements for
symbolic computing tools by scientists, and the recognition that
computing platforms, from desktop systems to supercomputers, are
rapidly moving to parallel designs.

It is a common experience of many users of symbolic computing
software that some of these computations can take enormous amounts
of run time. Thus symbolic computing is definitely an area that
could benefit from the potential of highly parallel computing. On
the other hand, the field of high performance computing stands to
benefit from the unique perspective of symbolic computing, with its
distinctive algorithms, sophisticated data structures and advanced user
interfaces. This meeting will promote the needed cross-fertilization
between these disciplines.

The specific objectives of the meeting are as follows:

1.Determine the requirements for current and future symbolic
computing tools, from the viewpoint of some scientists who actually
use such software.

2.Assess the current state of symbolic computing tools, particularly
on parallel computing platforms.

3.Identify the conceptual, algorithm and software challenges that
need to be solved to permit the deployment of effective symbolic
computing tools on the high performance computing platforms of
the future.
