Subject: A Matrix Minimax Problem

I have a matrix min-max problem to solve:

Max_X Min_Y log{determinant(Im + Y^{1-/2}H X H^T Y^{-1/2})}

where all matrix entries are over real numbers. H is any m-by-n matrix,
Im is the m-by-m identity and T denotes transpose. X is an n-by-n
positive semidefinite matrix satisfying: Trace(X) <= P, for P > 0. Y is an
m-by-m positive definite matrix which has the block structure:

|Ir Z^T |
Y = |Z I(m-r)| where r < m, and Ir and I(m-r) are the r-by-r and
(m-r)-by-(m-r) identities, and Z is some matrix such that Y >0.

Would you know of any good algorithms that solve this problem?
Specifically, does this Iterative algorithm converge?
Call f(X,Y) = log(det(I+Y^{1-/2}H X H^T Y^{-1/2})). First, fix
X = X0. Solve Y0 = argmin_Y f(X0,Y). Now find X1 = argmax_X f(X,Y0). In step
j+1, find Y(j+1) = argmin_Y f(Xj,Y) and X(j+1) = argmax_X f(X,Yj).
In other words, maximize with respect to X keeping Y constant and minimize
with respect to Y keeping X constant and repeat till it converges.
Practically, this algorithm is found to converge in a few minutes.

Thanks a lot for your help and patience.

Subject: Updating an Eigenvalue Decomposition

I am interested in efficiently solving the following problem in a
computational setting:

Matrix A is square, symmetric and positive definite; to fix ideas suppose
that the first row and column of A change (still preserving symmetry);
is there a way to compute the change in eigenvalues/vectors of A due to
the change in its first row/column?

I could do it through perturbation theory but I'd like to have some exact
and computationally feasible results. Any references welcome.

Subject: Seeking Implementation of LSQR Algorithm

I am looking for C/C++ implementation of LSQR algorithm, which doesn't need
store in memory the whole marix A in linear equation system Ax=b. Instead, it
should use results of linear operator A and conjugate operator A* operations.

Thanks

Subject: Nominations for Householder Award

HOUSEHOLDER AWARD XI - Final Announcement
Deadline: February 15, 2002

Nominations are solicited for the Alston S. Householder Award XI
(2002). The award will be presented to the author of the best
dissertation in numerical algebra submitted by the recipient of a
PhD earned between January 1, 1999, and December 31, 2001.

The term numerical algebra is intended to describe those parts of
mathematical research that have both algebraic aspects and numerical
content or implications. Thus, for example, the term covers linear
algebra that has numerical applications and the algebraic aspects of
ordinary differential, partial differential, integral, and nonlinear
equations. To qualify, the dissertation must have been submitted to
fulfill requirements for a degree at the level of a United States
Ph.D. Candidates from countries in which a formal dissertation is not
normally written at that level may submit an equivalent piece of work.

The Householder Award, given every three years, was established at the
1969 Gatlinburg Symposium (now renamed the Householder Symposium) to
recognize the outstanding contributions of Alston S. Householder,
1904--1993, to numerical analysis and linear algebra.

Entries will be assessed by an international committee consisting of
James Demmel (University of California, Berkeley), Ludwig Elsner
(University of Bielefeld), Volker Mehrmann (TU Berlin), Charles Van Loan
(Cornell University) and Olof Widlund (Courant Institute, New York
University).

The candidate's sponsor (the supervisor of the candidate's research)
should submit five copies of the dissertation (or qualifying work),
together with an appraisal by the sponsor and at least one additional
letter of recommendation supporting the nomination, by February 15, 2002, to

Professor Ludwig Elsner
Fakultaet fuer Mathematik
Universitaet Bielefeld
Postfach 10 01 31
33501 Bielefeld
Germany
email: elsner@Mathematik.Uni-Bielefeld.DE

The award will be presented at the Householder Symposium XV, to be
held June 17-21, 2002 at the Peebles Hotel Hydro, Scotland
(http://www.maths.strath.ac.uk/~matrix/).
Candidates on the short list will receive invitations to the meeting.

Previous Householder Award winners were F. Robert (Grenoble) in 1971,

Subject: Reprinted Book, Algorithms for Minimization

My book "Algorithms for Minimization without Derivatives"
(Prentice-Hall, 1973), which has been out of print for many years, has
just been republished by Dover (paperback, \$9.95), ISBN 0-486-41998-3

The book describes and analyzes some practical methods for finding
approximate zeros and minima of functions, using only function (not
derivative) evaluations. Contents include algorithms with guaranteed
convergence for finding a zero of a function of one variable,
a local minimum of a function of one variable, and a global minimum
given an upper bound on the second derivative.

Despite progress since 1973, much of the book is still relevant.

Subject: Cullum and Willoughby Books on Lanczos Algorithms

Dear Colleagues,

In the July 30, 2001 issue of Na-Digest I indicated that I would
be putting the two-volume book, Lanczos Algorithms for Large
Symmetric Eigenvalue Computations, Vol. 1, Theory: Vol. 2,
Programs, which Ralph Willoughby and I co-authored, on my LANL
website.

Since then, however, SIAM has decided to republish Volume 1
in the SIAM Classics Series. Consequently, I will be putting
only Volume 2 on my website.

I have received a few responses to my earlier request for

(1) any errors which need to be corrected

(2) any appropriate new citations (An annotation which summarizes
the contribution in the work cited would be greatly appreciated)

(3) the existence and availability of any updated versions
of the codes which are currently available from Netlib under

http://www.netlib.org/

However, if you intended to send some comments and have not yet
done so, please get them to me before Feb 24th. Please send to
either cullumj@lanl.gov using the subject heading 'Lanczos Book',
or by fax to 505-665-4972.

Thanks very much,

Subject: New Book, Automatic Differentiation of Algorithms

Announcing a new book:
Automatic Differentiation of Algorithms: From Simulation to Optimization
Edited by George Corliss, Christele Faure, Andreas Griewank,
Laurent Hascoet, Uwe Naumann
Springer 2002, ISBN: 0-387-95305-1
http://www.springer-ny.com/detail.tpl?ISBN=0387953051

Automatic Differentiation (AD) is a maturing computational
technology and has become a mainstream tool used by practicing
scientists and computer engineers. The rapid advance of hardware
computing power and AD tools has enabled practitioners to
quickly generate derivative-enhanced versions of their code
for a broad range of applications in applied research and
development.

"Automatic Differentiation of Algorithms" provides a comprehensive
and authoritative survey of all recent developments, new techniques,
and tools for AD use. The book covers all aspects of the subject:
mathematics, scientific programming (i.e., use of adjoints in
optimization) and implementation (i.e., memory management problems).
A strong theme of the book is the relationships between AD tools and
other software tools, such as compilers and parallelizers. A rich
variety of significant applications are presented as well, including
optimum-shape design problems, for which AD offers more efficient
tools and techniques.

Topics and features:
* introductory AD survey chapter for brief overview of AD
* extensive applications chapters
* comprehensive bibliography
* performance issues
* optimal control sensitivity analysis
* AD use with object oriented software tool kits

icsm2002.info@unisannio.it
Call for Papers
Theme: Maintaining distributed heterogeneous systems

ICSM is the major international conference in the field of software and
systems maintenance, evolution, and management. This year's theme
elaborates on last year's theme of "systems and software evolution in the
era of the internet". Standalone legacy applications of yesterday and
novel applications using today's technologies are rapidly becoming
integrated as part of enterprise-wide and industry-wide systems. The need
for rapid integration has led to many distributed heterogeneous systems
that are very challenging to maintain and evolve.

ICSM 2002 will address these new scenarios and the major challenges of
maintenance and evolution. The focus of the conference will be on the new
challenges that heterogeneous systems pose for software maintenance, and
the new opportunities for researchers and practitioners. A main goal of
ICSM is to promote interaction between researchers and practitioners. ICSM
2002 will bring together researchers, practitioners, developers and users
of tools, technology transfer experts, and project managers.

Jon Pincus (Microsoft) will describe how Microsoft handles software
enhancements. Other outstanding Keynote speakers are being arranged. Past
conferences have had Parnas, Rombach, McCabe, and Jacobson.

ICSM-2002 will offer technical presentations and demonstrations from
academia and industry. We are particularly interested in exchanging
concepts, prototypes, research ideas, and other results that could
contribute to the academic arena and also benefit business and the
industrial community. ICSM 2002 will be participatory, with working
collaborative sessions and presentations of industry projects.

The Conference will be held in conjunction with:

WESS -- Workshop on Empirical Studies of Software Maintenance.
SCAM -- Source Code Analysis and Manipulation
WSE -- Workshop on WEBsite Evolution

Topics of interest include but are not restricted to the following aspects
of maintenance and evolution:

- Methods and theories - Maintenance and/or productivity metrics
- Organizational frameworks - Preventive maintenance
- Design for maintenance - Tools and environments
- Life cycle and process control - Models/methods for error prediction
- User interface evolution - Commercial off-the-shelf (COTS)
- Third party maintenance - Freeware and open source applications
- Program comprehension - Software and system visualisation
- Knowledge based systems - Measurement of software
- Formal methods - Legal aspects and standards
- Software reusability - Internet and distributed systems
- Empirical studies - Testing and regression testing
- Remote, tele-work - Version and configuration management
- Processes and strategies - Management and organisation

Ettore Majorana Centre for Scientific Culture
International School of Mathematics "G. Stampacchia"
Erice - Sicily, Italy

Workshop
MATHEMATICAL DIAGNOSTICS
June 17 - June 25 , 2002

PURPOSE OF THE WORKSHOP
Stating a diagnosis is a decision making process that takes place in many
different fields of the human activities. It is, of course, a crucial step
in medicine, but also in a wide range of practical activities, such as
finance, pattern recognition, study of experimental data, astronomy,
engineering diagnostics, data mining etc. Quite often the diagnostic process
reduces to a classification process, i.e. to select exactly one set from
among several sets an individual can belong to. This is the typical case of
medical diagnosis, where for a given patient it has to be decided whether or
not he is affected by a specific pathology. In recent years effective
mathematical tools have been designed to support diagnostics. Optimization
methods as well as neural networks and decision trees have been successfully
adopted. From the mathematical point of view, diagnostics is strictly
connected to Hahn-Banach type theorems (separation properties of sometimes
inseparable sets in finite dimensional spaces). Many new and sophisticated
mathematical models are of a nonsmooth nature, in the sense that they
require to solve nonlinear optimization problems that involve
nondifferentiable functions. The workshop is intended for both people
interested in research and in applications; it is primarily aimed at
assessing the state-of-the-art of the subject, giving to the scientific
community the opportunity of comparing diverse approaches exposed by experts
coming from different fields. Additional objectives are to present the new
results that many scientists in several countries are obtaining by using
mathematical programming tools and to describe significant applications of
mathematical diagnostics. Participation of experts from application areas as
well as that of young scientists will be strongly encouraged.

Subject: Postdoctoral Position at the Institut Francais du Petrole

Postdoctoral position in statistics at the Institut Francais du Petrole.

The objective is to build a methodology to quantify the uncertainties
associated with predictions given by non-linear model in the field of refining
processes. We are in the case of EIV problems (Errors In Variables) and
the main difficulties come from the hight number of parameters in the model
and the CPU time required. This work will be carried out at the Institut
Francais du Petrole, CEDI Rene Navarre, in Solaize near Lyon and within the
Applied Mathematics Departement. Candidate should have a solid background
in statistics as well as experience in scientific programming. Join
Francois Wahl at francois.wahl@ifp.fr for more informations and application.

Subject: Summer Jobs at Los Alamos National Laboratory

I am looking for two graduate students who would be interested
in working together this summer at the Los Alamos National
Laboratory on the parallelization of several Lanczos-based
algorithms for solving large-scale eigenvalue/singular value
problems.

This summer experience would entail taking existing uni-processor,
Lanczos-based eigenvalue/singular value algorithms and converting
them into corresponding parallel algorithms which take advantage
of the functionality of various parallel computers.

The resulting software will be packaged and put on the web for
public distribution.

Desired Skills:

Some experience working on parallel numerical algorithms and in
writing software, some knowledge of MPI, and an interest in working
on/devising new parallel algorithms.

Completion of at least one year of graduate school. Some knowledge of
linear algebra, sparse matrix manipulations and operations, and some
experience coding in Fortran 90.
