**Subject: Positive Semidefinite Constraints**

In response to last week's question about positive semidefinite matrix

constraints: the semidefinite restriction should be imposed as a constraint

on the symmetric matrix variable. Although this constraint is not

differentiable, it is convex and can be handled extremely efficiently by

interior-point optimization methods. A good reference is Vandenberghe and

Boyd's survey article in SIAM Review, March 1996, p.49.

due to some technical problems the HPCN97 WEB pages

(http://www.wins.uva.nl/research/HPCN97) which contain all the submission

details were not available for some time. Therefore, after many requests,

the organising committee has decided to add 10 more days to the deadline.

We would really like to encourage you to submit a paper for this very

**Subject: New Book on Noisy Information and Computational Complexity**

NEW BOOK ON

`Noisy information and computational complexity'

by Leszek Plaskota

Cambridge University Press 1996

This is the first book in which noisy information is studied in

the context of computational complexity, in other words it deals with

the computational complexity of mathematical problems for which available

information is partial, noisy and priced. The author develops a general

theory of computational complexity of continuous problems with noisy

information and gives a number of applications; deterministic as well as

stochastic noise is considered. He presents optimal algorithms, optimal

information, and complexity bounds in different settings; worst case,

average case, mixed worst-average and average-worst, and asymptotic.

Particular topics include the existence of optimal linear (affine)

algorithms, optimality properties of smoothing spline, regularization

and least squares algorithms (with the optimal choice of the smoothing

and regularization parameters), adaption versus nonadaption, and

relations between different settings.

The book integrates the work of researchers over the last decade in such

areas as computational complexity, approximation theory and statistics,

and includes many new results as well. About two hundred exercises are

supplied with a view to increasing the reader's understanding of

the subject. The material is organized in such a way that it can be used

either as a textbook for advanced courses, or as a standard reference for

professional computer scientists, statisticians, applied mathematicians,

engineers, control theorists, and economists.

**Subject: Conference Report: ODE to Linear Algebra and Rational Approximation **

ODE to Linear Algebra and Rational Approximation

On November 1st and 2nd, 1996, approximately fifty well wishers

gathered at the Naval Postgraduate School in Monterey, California,

to celebrate the 60th birthday of William B. Gragg (b. 7:01 am,

November 2nd, 1936, in Bakersfield, CA).

Over the years Bill Gragg has demonstrated a remarkable knack

for discovering connections between seemingly unrelated areas.

Examples are the connections between the Pade table, the Lanczos

algorithm, and the partial realization problem of linear system

theory and the connection between Levinson's algorithm for solving

Toeplitz systems and Szego's recursions for generating orthogonal

polynomials on the unit circle. The focus of the conference was on

these and other areas of mathematics and scientific computing where

Bill has made contributions, including ordinary differential

equations, linear algebra, and rational approximation. The broad

range of topics covered in the thirty-one presentations serves as a

strong testimony to Bill's influence. A complete summary of the

proceedings is beyond this correspondent's capacity, but a partial

list of topics will surely help to give the flavor: tridiagonals,

QR algorithm, SVD, moment matching, Pade conjecture,

Lanczos algorithms, Lanczos-Pade connection, partial realization,

orthogonal polynomials, control, Riccati equations,

unitary eigenvalue problem, fast Toeplitz (Hankel, Vandermonde,

Cauchy, etc.) solvers, isometric Arnoldi process, growth factors in

Gaussian elimination, and on and on. A complete list of speakers

and titles is available at the Gragg Conference Homepage:

http://math.nps.navy.mil/Conference/.

One particularly memorable talk was Leslie Foster's presentation on

pivoting strategies for Gaussian elimination. Les produced a notebook

from a numerical analysis course that he took from Bill in the Fall of

1970 at UC San Diego. He displayed a page from the day on which Bill

had outlined some of the known facts about growth factors in Gaussian

elimination. Then he proceeded to inform us about the substantial

progress that has been made since 1970 in this active area.

We also enjoyed Gerhard Opfer's slides of the unusual home in Lexington

that Bill owned when he was a professor at the University of Kentucky.

All had a merry time at the Conference Banquet Friday night. The most

prevalent beverage at the cocktail hour was Guiness. After dinner

many of the attendees shared stories (mostly true, I believe) about

Bill Gragg the mathematician and Bill Gragg the human being.

Thanks to conference organizers Greg Ammar, Carlos Borges, Daniela

Calvetti, and Lothar Reichel for putting on a great party.

Undergraduate Internship Program

in Biophysical Computing and Computational Dynamics

Program Announcement

Summer 1997

The Supercomputer Institute is pleased to announce an Undergraduate

Internship Program in Biophysical Computing and Computational Dynamics for

Summer 1997.

The program is sponsored by the Supercomputer Institute at the University

of Minnesota and by the Research Experiences for Undergraduates Program of

the National Science Foundation. Research projects are available in

biochemistry, chemistry, chemical physics, molecular biology, molecular

geophysics, pharmacology, and physiology. There are opportunities for

computer science students as well as for majors in these and related

fields.

The program's objective is to promote undergraduate involvement in

ongoing and new research in biophysical computing and computational

dynamics and in new software development efforts for scientific computing

and graphics support for such research, as well as to carry out useful and

interesting research. Our program provides an opportunity for a

challenging and enriching educational experience for undergraduate students

who are interested in pursuing graduate or professional education and

research in scientific computing and graphics.

Summer appointments will be full-time, ten-week appointments. The 1997

program will run from June 16 through August 22, 1997. The stipend is

$3,750 for ten weeks, which includes travel and living expenses. A student

interested in becoming an intern must be an undergraduate student at the

time of the internship to be eligible and must be a citizen or permanent

resident of the United States and its possessions.

Undergraduates will work with faculty on a wide variety of projects.

Faculty from various disciplines have individually contributed projects on

topics that fall within the areas delineated above and will be responsible

for supervising the undergraduate students in their daily work. A document

describing available projects and opportunities is available and is updated

frequently. Students should indicate their interests in specific projects

on their application forms.

All applications are judged competitively based on the qualifications of

the applicant and the availability of a suitable project. To obtain an

The following problem was first posed by Glasser

(Problem 95-7, SIAM Review, V 38,N 2,p.324,1996)

Evaluate K(a), where

K(a) = \int_0^{\infinity} [ (exp(-x) + exp(x))^a - exp(-ax) - exp(ax) ] dx

and 0 < a < 2, in terms of Gamma functions.

It was noted therein that K(5/3) is approximately 4.45

The solution is published ( Ismail and others,see above ref.). Several solvers

noted that a more accurate answer is 4.626291112. They did not indicate

whether this approximation is obtained by numerical integration.

My quesyion is: What is the best double precision approximation to K(5/3)?
