Subject: Nonlinear Constrained Optimization and PDEs
A student of mine asked me to post the following problem in the NA digest.
Your comments and suggestions are welcome at my address.
Alexander Ostermann
Universit\"at Innsbruck, Austria
alex@mat1.uibk.ac.at
We have to solve a quasilinear system of two partial differential equations
a u_x + b u_y + c v_x + d v_y = 0
u_x v_y - u_y v_x = e
with unknowns u=u(x,y), v=v(x,y) and coefficients a=a(x,y,u,v), etc.
on a square. We discretized with finite differences. Since we do not
know the appropriate boundary conditions for this problem, we consider the
boundary points as unknowns, too.
To guarantee the injectivity of the mapping (u,v), we impose the inequalities
const1 < u_{1,1} < u_{1,2} < ... < u_{1,N} < const2
const3 < u_{2,1} < ... < u_{2,N} < const4
... and so on ...
This gives a system of 2(M-2)(N-2) nonlinear equations with (N-2)M+(M-2)N
unknowns and (N-3)M+(M-3)N linear constraints. As the number of unkonwns
exceeds the number of equations we replaced our problem by the following:
Minimize an object function (the sum of squares of the above nonlinear
functions) subject to the above constraints.
Using NAG's E04VDF we implemented a code that solves the system, but E04VDF
is very RAM-consuming (we can only use a 486 PC under MS-DOS) as it does
neither consider that the object function is a sum of squares of nonlinear
functions, nor that its Jacobian is sparse, nor that the constraints are
sparse. We managed to solve a 8x7-mesh but we wish solve the problem for
at least M=40 and N=40, preferably for M=100 and N=100.
We also tried a (conjugate) gradient method and introduced slack-variables
to keep the constraints. Unfortunately, this did not work (maybe due to the
high number of variables). We are still searching literature on gradient
methods for constrained minimization.
To summarize: We are interested in literature and software for minimizing an
- object function (the norm of several thousand nonlinear functions
containing sin,cos,...) with sparse Jacobian
- with several thousand unknowns
- subject to sparse linear constraints (inequalities).
- Recall that our problem is underdetermined (more unknowns than functions).
If you think that our approach to the problem, sketched above, is not
very promising, please let us know. Thank you very much for your kind help!

Subject: Test for Containment in Convex Hull
Suppose we are given a finite set S = {v_1,...,v_k}
of points in Euclidean space R^n, where it is assumed that k > n.
Question:
Is there an efficient algorithm for determining whether the
origin 0 of R^n lies in the convex hull Hull(S) of S ?
(I suspect there is a route that uses linear algebra
exclusively, without the need to explicitly compute Hull(S).)
Note:
One way to look at this question is as follows:
Let L: R^k -> R^n be the linear transformation whose matrix
with respect to the standard bases is given by (v_1,...,v_k).
Then 0 lies in Hull(S) if and only if the kernel of L intersects the
positive orthant O_k of R^k.
So, the Question is equivalent to the following: given any linear
transformation L: R^k -> R^n with k > n, determine whether ker(L)
intersects the positive orthant O_k of R^k.

MATLAB Primer, Third Edition
The Third Edition of the MATLAB Primer is now available. It is
based on version 4.0/4.1 of MATLAB and reflects an extensive revision
of the Second Edition. It is available via anonymous FTP from:
Address: math.ufl.edu Directory: pub/matlab File: primer.tex
and at
Address: ftp.mathworks.com Directory: pub/doc/primer File: primer.tex
Also available at these FTP sites are both
English (primer35.tex,primer35.ps) and
Spanish (primer35sp.tex, primer35sp.ps)
versions of the Second Edition of the Primer, which was based on
version 3.5 of MATLAB. The Spanish translation is by Celestino
Montes, University of Seville, Spain. A Spanish translation of the
Third Edition is under development.
The MATLAB Primer was written to help students begin to use MATLAB.
It is intended to serve as an introduction to and *not* a manual for
MATLAB. While its primary purpose is for use in courses which
require use of MATLAB, it could, of course, serve as an introduction
to MATLAB for others. It is intended to be distributed via a local
copy center.

Subject: NSF High Performance Computing
We are writing to ask you to help us plan the future of High Performance
Computing at the National Science Foundation.
The NSF Blue Ribbon Panel on High Performance Computing chaired by
Professor Lewis Branscomb has issued their report. It is the product of a
cross-disciplinary panel of scientists and engineers who were asked to
consider a breadth of contributions, barriers, and opportunities for High
Performance Computing (HPC), primarily within an NSF context. If you do not
have a copy of the report you may get one electronically or by contacting
one of the individuals listed below.
The Panel identified four challenges and four broad recommendations. The
spirit of the recommendations are embodied in the two "pyramid" figures on
page viii, involving computing environments (equipment) and computing
institutions (researchers, organizations).
The challenges focus on the need to remove barriers to effective and
efficient use of HPC, to broaden the base of participation in HPC, to
provide "scalable" access to a pyramid of computing resources including the
software and infrastructure required to make them useable by the scientific
community, and to create the intellectual and management leadership for the
future of HPC in the US.
An NSF internal working group has been established to develop a response to
the recommendations in this report. The timetable for this working group is
short; its work is expected to be done by the beginning of April. The
working group consists of individuals from each Directorate, who have been
appointed by their respective Assistant Directors:
William Bainbridge Social, Behavioral & Economic Sciences
Richard Hirsh Computer & Information Science & Engineering
Clifford Jacobs Geosciences
George Lea Engineering
Nora Sabelli Education & Human Resources
Karen Sigvardt Biology
Alvin Thaler Mathematical & Physical Sciences
We would appreciate it if you would share this note and the report with
members of your community. Please direct comments or recommendations on
issues raised in this report to the co-chairs of the NSF HPCC planning
group listed below. Your comments must be received by January 14, 1994
in order to have the most impact on our response.

Copies of the report are available electronically on the
Internet from the NSF Science and Technology Information System (STIS).
This can be reached by using Mosaic or Gopher; via telnet at stis.nsf.gov,
and typing public at the prompt; or by sending an e-mail message to
stisserv@nsf.gov and putting stisdirm in the text, instructions will be
sent back to you.

CONTRIBUTED MINISYMPOSIA
Six minisymposia will be selected from contributed proposals to
complete the set of conference themes. Minisymposia will be two-hour
sessions, intended to provide a high-level survey of current research
in an important area of applied linear algebra. This conference will
have significantly fewer minisymposia than previous Applied Linear
Algebra meetings; most of the topics that would otherwise be minisymposia
will instead be discussed in the common-interest sessions (see below).
The complete call for papers contains instructions for proposing a
minisymposium.
CONTRIBUTED PAPERS
As an experiment, this meeting has been organized so that the
presentation of contributed papers will be a dialogue rather than
a monologue. Each paper may be presented in three forms: in a
proceedings volume, as a poster display, and as part of a 2-hour
"common interest" discussion session. We expect most of the
contributed papers to be presented in all three forms, though this
is not required. The complete call for papers contains details.
REGISTRATION
The conference program and registration information will be available
in early March 1994. To ensure receiving your copy, complete the reply
card attached to the complete call for papers and return it to SIAM by
either email or hard mail.
**Prospective participants must complete and return this card by
December 13, 1993.**
Hard copy of the call for papers and reply card is (as usual) being
mailed to SIAM members.
