Subject: Optimization Problems with Eigenvalue Constraints

Reply Concerning Optimization Problems with Eigenvalue Constraints

(In response to question raised by F. Alizadeh)

Let A(x) be a real symmetric matrix depending on a vector x of several
variables. In general it is not possible to order the eigenvalues of A(x)
so that they are individually differentiable functions of x; for example
consider A(x_1,x_2) = [1+x_1 x_2 ]
[x_2 1-x_1]
so that the eigenvalues are 1 +/- sqrt(x_1^2 + x_2^2). For further details
see Kato, A Short Intro to Perturbation Theory for Linear Operators, p.133.

It is commonly the case that an optimization problem involving eigenvalues
of A(x) has a solution x where A(x) has multiple eigenvalues. For example,
this is the case when the maximum eigenvalue of the example given above is
minimized, or equivalently an extra variable x_3 is minimized subject to
x_3 >= the eigenvalues of A(x_1,x_2). As pointed out by F. Alizadeh in his
message, standard optimization methods fail to work on these problems.

In an article in SIMAX (SIAM J. Matr. Anal. Appl.) 9 (1988) 256-268,
I presented an algorithm for minimizing the maximum eigenvalue of a matrix
A(x) which has generic quadratic convergence even to nonsmooth solutions,
i.e. those where multiplicity > 1 occurs at the solution. The algorithm is
very efficient (for small-scale problems) because it takes full account
of the structure of the subdifferential of the max eigenvalue function.
Furthermore, if a solution has an active multiple eigenvalue of
multiplicity t, the algorithm generates a t by t symmetric "dual matrix",
which is used for sensitivity analysis of the solution and is the
generalization of the idea of a dual variable (Lagrange multiplier)
familiar from linear or nonlinear programming. The ideas underlying the
algorithm make use of work of Fletcher on optimization subject to matrix
semi-definite constraints and Friedland, Nocedal and Overton on inverse
eigenvalue problems. The same ideas can be used to handle optimization
problems where the eigenvalues appear in the constraints rather than in
the objective function. Rob Womersley and I are currently writing a paper
showing how to extend these ideas to minimize sums of largest eigenvalues.

The presence of the t by t symmetric dual matrix is intimately related
to the von Neumann-Wigner "crossing-rule" well known in quantum mechanics,
which states that for an eigenvalue to have a particular value with
multiplicity t amounts to imposing, not t, but t(t+1)/2 linearly independent
conditions on the parameter space. This formula is also well known in matrix
factor analysis, where a particular rank is imposed on a matrix. In the
latter case the formula is usually derived using determinants, but there
are good reasons to avoid the use of determinants either for theoretical
development or for computational purposes.

A paper which will be available soon describes my experience on
extending the ideas of the algorithm given in SIMAX to solve large-scale
eigenvalue optimization problems. Steve Cox and I have successfully used
this approach to compute the shape of the strongest beam, a classical
problem of Lagrange which has led to great controversy in the literature
because of the presence of a double eigenvalue of the associated fourth-order
differential equation at the solution. Anne Greenbaum and I are
applying the same approach to compute optimal preconditioners
for large linear systems, extending the work of Greenbaum and Rodrigue
which used my SIMAX algorithm to find, for example, that the optimal
tridiagonal preconditioner for the discrete Laplacian involves double
eigenvalues. I have also used the new large-scale algorithm to solve
eigenvalue optimization problems for graphs, which have applications
to bounding the Shannon capacity of a graph, a problem brought to my
attention by J. Zowe. In this case solutions typically have moderately
large eigenvalue multiplicity. Another application of interest is computing
the structural singular values of a matrix, an important topic in control.

I mention all these applications because I am sure there are many more
out there, to which these ideas can be applied. If you are interested
in receiving a copy of the paper on large-scale eigenvalue optimization,
send me e-mail (

Subject: Post Doc Research Associateships at NSF

Division of Advanced Scientific Computing
Washington, DC 20550

January 11, 1990
Dear Colleague;

The New Technologies Program in the Division of Advanced
Scientific Computing will provide support for Postdoctoral
Research Associateships in Computational Science. The deadline
for submission of proposals and application materials is APRIL 1,
1990. Awards will be announced in May, 1990. In FY 1990, the
Division of Advanced Scientific Computing anticipates making
approximately five to six awards. The objective of the
Associateship Awards is to provide opportunities for young
scientists to broaden their knowledge and experience and to
prepare them for significant research careers on the frontiers of
contemporary computational science. The Associateships awards
will be based on proposals submitted by the research associate in
cooperation with a host institution and including a named
principal investigator who will serve as an unreimbursed
scientific advisor. Each proposal must include a research and
training plan for the proposed research associate in an activity
of computational science and engineering in any of the fields
supported by NSF.


To be eligible for this support, individuals must;

(1) be eligible to be appointed as a research associate in
the host institution which has submitted the proposal,

(2) fulfill the requirements for the doctoral degree in
computational science or a closely related discipline by
September 30, 1990,

(3) have research interests that fall within the program
areas of the Division of Advanced Scientific Computing,

Location of Work

The New Technologies Program Postdoctoral Research Associateships
in Computational Science are intended to support scientific
research in high performance computing at academic research
institutions, such as, one of the NSF supported Supercomputer
Centers, or other centers or institutions which provide access to
high performance computing systems and concentrate on associated
research programs. The proposal must contain a statement
indicating a commitment for center, or institutional, facilities
and resources.

Stipends, Research Expense Allowances and Cost Sharing

Normally, awards will provide support through a standard grant
for 24 months. The NSF Associateship awards will range from
$32,000 - $40,000 over a 24 month period, to be matched equally
by the sponsoring institution. The annual award to the research
associate will be composed of two parts; an annual stipend
(salary and benefits), and a $4,000 per year research expense
allowance to aid in defraying costs associated with the
research.The stipend will be paid to the research associate at an
annual rate that may range from $28,000 - $36,000. To the extent
that the sponsoring institution increases its cost sharing by
providing an additional stipend increment, of up to $8,000 over
the 24 month award period, the NSF will provide a matching award
over the 24 month period. The annual $4,000 research expense
allowance is expendable at the Associate's discretion and will
normally be used for travel, publication expenses, and other
research-related costs. There is no allowance for dependents. The
award will start upon request by the Associate after acceptance
of an award offer, but not later than January, 1991.

Evaluation and Selection of Associates

An ad hoc review panel will be asked to consider the adequacy of
the institutional high performance computational resources
available in support of the proposed research plan. The
evaluation of applicants will be based on their ability,
accomplishments, and potential as evidenced by the quality and
significance of past research, long range career goals and the
likely impact of the proposed postdoctoral training and research
plan on the future scientific development of the applicant. The
selection of Associates will be made by the National Science
Foundation on the basis of the recommendations of the panel and
with due consideration to the effect of the awards on the
infrastructure of computational science in the United States.
Successful applicants will be notified by letter in May 1990.

Application Procedures and Proposal Materials

To be eligible for consideration, a proposal must contain;

(1) one original and nine copies of;

(a) a cover page with institutional certifications (Form
1207) and a budget with details regarding institutional
matching (Form 1030, see NSF Publication 83-57, Grants for

Subject: Course on the MODULEF Finite Element Library

Pennsylvania State University
July 16-20, 1989

Club MODULEF was created in 1974 to bring together researchers
from academics, government, and industry interested in developing
a finite element program library with the following features:

o access to source code, enabling users to add and modify

o modular organization

o rapid incorporation of current theoretical developments

At present the club has about 250 institutional members from around the
world. The MODULEF library presently contains over 300,000 lines of
FORTRAN code and is being expanded continually. Though based in
France, at the Institut National de Recherche en Informatique et en
Automatique (I.N.R.I.A.), there is presently a major effort to make all
the documentation available in English.

Courses in the use of MODULEF have been offered regularly in France.
Because of the increasing American membership in Club MODULEF, such a
course is being offered for the first time in the United States. The
aim of the course is to introduce new users to the MODULEF library and
teach them both to use existing modules and incorporate new modules.

I. Using existing modules
o A sample physical problem
- variational formulation
- approximation by finite elements
- steps in the implementation

o The MODULEF library
- organization of the library
- principle modules
- interactive use
- writing a calling program

o Examples and hands-on use

II. Creating new modules
We will explain how to create new modules to
be used with existing modules in order to
expand the capability of the library

The course will be held at the Pennsylvania State University in
University Park, Pennsylvania. It will run from Monday to Friday,
July 16-20, 1990.

Tuition is $200 for full-time academic participants and $500 for
industrial participants. Tuition includes a copy of "MODULEF: A
Modular Library of Finite Elements", a 350 page tutorial and reference
PARTICIPANTS TO REGISTER. Tuition must be paid at the time of
