**Subject: Benchmarks for Optimization Codes**

Recently, I have started a webpage listing benchmark results for

optimization codes, mostly those in the public domain. It is located at

http://plato.la.asu.edu/bench.html

and is really part of the webpage "Decision Tree for Optimization Software",

http://plato.la.asu.edu/guide.html that Peter Spellucci and I are maintaining.

Presently, there are two own benchmarks and one link:

1) Benchmark of some public domain interior point LP solvers

comparing HOPDM, LIPSOL, LOQO, PCX

2) Benchmark of LANCELOT and SNOPT on the large CUTE testset

3) Results for PCx on a large number of platforms

(netlib and other testproblems)

Other benchmark results will be added in the near future. Comments are

welcome as are suggestions for other benchmarks to be done or hints to existing

results which could be added resp. be linked to.

The volume has three goals. First, to summarize the state of the art in

the area of high performance solution of structured linear systems as well

as of structured eigenvalue and singular-value problems. Second, to

indicate what research directions are perceived as the most important for

the future. Third to provide a collection of algorithms and ideas that

may enhance future development in this area.

Detailed information about the volume can be found at:

**Subject: Student Paper Award for Reliable Computing**

1996 Best Student Paper Award for the "Reliable Computing" Journal

In 1993, the editorial board of the "Interval Computations" journal

(now called "Reliable Computing") announced that papers submitted for

the special student issue will be automatically entered

into an annual Best Student Paper contest.

The referee reports and the reports from the members of the editorial

board of "Reliable Computing" served as the basis for choosing the best paper.

It was a difficult decision to make because we have received several

excellent papers.

We are pleased to announce the results. The 1996 best student paper award

is awarded to the paper "Newton's constant of gravitation and verified

numerical quadrature" by Oliver Holzmann, Bruno Lang, and Holger Schuett.

This paper is published in "Reliable Computing", 1996, Vol. 2, No. 3,

pp. 229-240.

In addition to being a very good paper, it is devoted to an important

application (measuring the gravitational constant) that has led to a

good publicity for interval computations (in "Discover", one of the

major popular science journals).

Congratulations to Oliver Holtzmann, the student author of this paper,

and thanks to all other students authors for their excellent job.

Abstract:

This book focuses on the theory, implementation and applications

of subspace identification algorithms for linear time-invariant

finite-dimensional dynamical systems. These algorithms allow for

a fast, straightforward and accurate determination of linear

multivariable models from measured input-output data.

The theory of subspace identification algorithms is presented in detail.

Several chapters are devoted to deterministic, stochastic and combined

deterministic-stochastic subspace identification algorithms.

For each case, the geometric properties are stated in a main 'subspace'

Theorem. Relations between existing algorithms and literature are

explored, as are the interconnections between different subspace

algorithms. The subspace identification theory is linked to the theory

of frequency weighted model reduction, which leads to new implementations

and insights.

The implementation of subspace identification algorithms is discussed

in terms of the robust and computationally efficient RQ and singular

value decompositions, which are well-established algorithms

from numerical linear algebra. The algorithms are implemented in

combination with a whole set of classical identification algorithms,

processing and validation tools in Xmath's ISID, a commercially available

graphical user interface toolbox. The basic subspace algorithms in

the book are also implemented in a set of Matlab files accompanying

the book.

One application of ISID to an industrial glass tube manufacturing

process is presented in detail, illustrating the power and

user-friendliness of the subspace identification algorithms and of

their implementation in ISID. The identified model allows for an

optimal control of the process, leading to a significant enhancement of

the production quality. The applicability of subspace identification

algorithms in industry is further illustrated with the application of

the Matlab files to ten practical problems. Since all necessary

data and Matlab files are included, the reader can easily step through

these applications, and thus get more insight in the algorithms.

**Subject: Position at University of Nijmegen**

Position at the Faculty of Mathematics and Informatics,

University of Nijmegen

Ph.D. position

There is an opening at the Faculty of Mathematics and Informatics,

University of Nijmegen, the Netherlands of a ph.d. position

(``onderzoeker in opleiding'').

It concerns Functional Languages in Numerical Analysis; a testcase and is a

joint project between prof. O. Axelsson (Numerical Mathematics) and

profs H. Barendregt and M.J. Plasmeijer (Informatics).

The major purpose of the project is to provide evidence that parallel

codes for large scale problems as arising in scientific computing can be

efficiently implemented using functional languages. Specifically, when

solving very large scale systems of equations such as occur for the

Helmholtz equation in 2D and 3D for several frequencies of the

irradiating waves used in ultrasound tomography, for instance, there is a

need to develop new and faster algorithms, which can give an accurate answer

in real time during the examination of the object (such as a human body).

To this end parallel computing must be used with scalable algorithms.

A new class of additive preconditioning multilevel iteration methods

will be developed and compared with previous multiplicative type of

methods. To simplify the programming and to optimize the code for a parallel

environment, existing functional languages will be further developed and used

in an interactive way with program transformation techniques for the iteration

solution code. Such a mode of working requires intensive collaboration from

teams from both mathematics and computer science. For this, the

required supervising personnel as well as hardware, is available locally.

For this position we are searching for a candidate who has finished or will

finish shortly his/her university studies in numerical mathematics or in

informatics and who is at most 26 years of age.

The project requires someone who has extensive knowledge of numerical

mathematics, who has excellent university marks (''cum laude'') and who has a

documented interest for computer science and parallel algorithms.

Appointment will be in temporary service with NWO, the Netherlands

Organization for Scientific Research, for at most four years.

Salary will be Dfl. 2.144 in the first year, rising to Dfl. 3.775

in the fourth year. Women and candidates coming from one of the member

states of the European Union are particularly asked to apply.

Anyone interested in this position who fulfills the above requirements is

requested to apply, preferably via e-mail, to Owe Axelsson

before November 11, 1996.
