Subject: Bram van der Sluis

With much regret I have to inform you that our colleague
Bram van der Sluis passed away last Saturday (March 20, 2004).

Bram van der Sluis was a full professor in Numerical Mathematics with
the Mathematical Institute at Utrecht University in the period 1962 - 1988.
Heavily influenced and inspired by late Jim Wilkinson's work, he
contributed to the area of numerical linear algebra with papers on
equilibration, condition numbers, scaling, and perturbations of
eigenvalues. This work, published in the late 1960s and the 1970s
is still cited. Later he became interested in sparse matrix problems
and together we have published papers on the superlinear convergence
behavior of the CG method, regularizing effects of CG and on the
convergence of Ritz values in the late 1980s.
I was one of his PhD students and I am thankful for the many deep
discussions that I had with Bram on topics around iterative methods.

Bram van der Sluis attended many Householder Symposia (previously Gatlinburg
Conferences) and was also a regular guest at Oberwolfach meetings.
After his retirement in 1988 he was still a regular guest at our
department, but was no longer seen at International meetings.
About six years ago he developed health problems and although these did
not seem too serious initially, they became limiting over the past year
and some three months ago he learned that he would not have to live
long anymore. This did not have much effect to his good spirits; at least for
his colleagues at our institute it came as a shock to learn that he was
in his final stage last week.

Bram is survived by his wife Helga, his four children and ten grandchildren.
We remember him as an inspiring teacher, a dedicated researcher and a great
colleague who did more than his share in organizational work for our
institute and for the Dutch numerical community.

The Farewell meeting will be on Thursday, March 23.

Subject: Linear Algebra Software Survey

I'm planning to update the survey of freely available software for the
solution of linear algebra problems. The April 2003 version of the survey
can be found at:

The aim is to put in "one place" the source code that is freely available
for solving problems in numerical linear algebra, specifically dense, sparse
direct and iterative systems and sparse iterative eigenvalue problems.
Please send me updates and corrections. I will post a note on the na-digest
when the new list is available.

Subject: New Book, Metodi di Calcolo Numerico per L'ingegneria

I would like to announce the new book:

FM. Denaro,
Metodi di calcolo numerico per l'ingegneria, Liguori Editore
ISBN: 88-207-3668-3, ed.: 2004, pp.: 232

which is devoted to the three-years academic courses in engineering.
This book considers the Lagrangian interpolation in 1 and 2 dimensions
and the cubic spline, the techniques of numerical derivation and
integration, their accuracy analysis, both in the physical and Fourier
space, and the iterative methods for linear systems.
Many examples are reported, some of them resolved by means of Maple,
others with Matlab. Some Fortran examples are also reported.
Language is Italian, English translation is planned in the future.

Best regards
Filippo M Denaro

Subject: SNOBFIT for Robust Noisy Optimization

SNOBFIT (Stable Noisy Optimization by Branch and FIT)
is a MATLAB 6 package for the robust and fast solution
of noisy optimization problems with continuous variables
varying within bound, possibly subject to additional
soft constraints. Discrete variables are not supported.

Objective function values must be provided by a file-based
interface; care is taken that the optimization proceeds
reasonably even when the interface produces noisy or
even occasionally undefined results (hidden constraints).
The interface makes it possible to use SNOBFIT with new
data entered by hand, or by any automatic or semiautomatic
experimental system.

This makes SNOBFIT very suitable for applications to the
selection of continuous parameter settings for simulations
or experiments, performed with the goal of optimizing some
user-specified criterion. Since multiple data points can be
entered, SNOBFIT can take advantage of parallel function

The method combines a branching strategy to enhance the
chance of finding a global minimum with a sequential
quadratic programming method based on fitted quadratic
models to have good local properties. Various safeguards
address many possible pitfalls that may arise in practical
applications, for which most other optimization routines
are ill-prepared. Soft constraints are taken care of by
a new penalty-type method with strong theoretical properties.

Source code and a description of the methods used can be
found at
or via my Global (and Local) Optimization web site.

Subject: Workshop at Fields Institute on Mathematical Oncolgy

Registration is still open for a focussed workshop on mathematical
oncology to be held 23-24 April 2004 at the Fields Institute for Research
in the Mathematical Sciences, Toronto.
The invited speakers are roughly equally split between medical/clinical
researchers and applied mathematical researchers and will speak on a
variety of topics in oncology of current interest. The intention is that
the talks be accessible to both communities and hopefully stimulate
further collaborative, interdisciplinary research.
Very limited funding is still available for graduate students and
postdocs. Further information can be found at:
