Subject: Help with Evaluation of Green's Function

Dear all.

The free-space Green's function is an important component of much
electromagnetic theory. Its definition is G=exp(-jkr)/r, where r=sqrt(x**2
+ c**2) and k=2*pi/wavelength, which immediately reveals that it has a
potential singularity at x=0, c=0. This obviously causes problems, in
particular as it is usually found inside a double integral. When
integrating G, one way around the problem is to "regularize" G by
subtracting a 1/r term. This latter term is then resolved analytically.
However such an approach has a big problem (which is usually ignored) in
that the regularized portion of G does not rigorously satisfy the
requirements of most, if not all, integration formulae. This is so because
it is not 'smooth' - it does not have well defined, finite, high-order
derivatives.

To solve this problem, I have expanded G in a Taylor/Maclaurin series and
integrated term-by-term. So far, no problem. However, there is no real
way of knowing the accuracy of the result, as there is no analytical answer!
There are analytical answers to the integral of (x**n)*G, when n=1,3,5,7...
When the term-by-term approach is applied to these functions (and they have
value in their own right), and the answers are compared to the analytical
results, two findings emerge: 1) accuracy deteriorates as n increases and
2) the errors get worse as the upper limit of integration decreases ( the
lower limit is usually zero). This latter observation is very disturbing
as practical application often requires this.

I have applied all the "best practice" techniques that I am aware of, but I
must be missing something. It would be very helpful to me if someone
could point me to book/paper references that discuss techniques for
computing series summations accurately.

Many thanks for your interest.

We are pleased to announce the release of GALAHAD V1.0, a library
of thread-safe Fortran 90 packages for large-scale nonlinear
optimization. GALAHAD includes two packages for nonconvex quadratic
programming (one being interior-point based, the other is of the
active/working set variety), a quadratic programming preprocessing
package, an updated version of LANCELOT, and a number of other
subsidiary optimization-related tools. Full PostScript and PDF

Subject: MathOptimizer Software for Mathematica

MathOptimizer
An Advanced Modeling and Optimization System for Mathematica Users

Technical Summary

Mathematica (www.wri.com) offers a sophisticated, fully integrated
environment for scientific and technical computing.

MathOptimizer is a native Mathematica product that enables the global and
local (numerical) solution of a very general class of optimization problems
defined by a finite number of functions over a finite n-dimensional
interval region. Formally, the model type considered is

min f(x) (objective function)
g(x) <= 0 (inequality constraint functions)
h(x) = 0 (equality constraint functions)
xl <= x <= xu (finite bound constraints)

By assumption, all arguments are real-valued; all functions are real-valued
and continuous.

A special emphasis is placed upon nonlinear models, including those that
have a - typically unknown - number of local optima. Nonlinear and global
optimization problems are ubiquitous in the sciences, engineering, and
economics. Several prominent examples are systems of nonlinear equations
and inequalities, nonlinear regression, forecasting models, data
classification, minimal energy models, various packing problems, risk
management and other stochastic decision problems, and the design and
operation of 'black box' engineering systems (possibly defined by a
complicated, numerically intensive procedure).

MathOptimizer currently consists of two core solver packages and a solver
integrator package. One of the solvers serves for (in practice, typically
approximate) global optimization on a given interval range, in the possible
presence of added constraints. This package is based on an efficient
adaptive stochastic search procedure. The second solver package is based on
a standard nonlinear (convex) programming approach: this solver can be used
for 'precise' local optimization, based on a given ('sufficiently good')
initial solution. The solver integrator package supports the individual or
combined use of the solver packages, but both of these solvers can also be
used in a stand-alone mode. (Further solver modules are under development,
and will be made available soon.)

The detailed (over 70-page) MathOptimizer User Guide includes concise
mathematical background notes and useful modeling tips; it also discusses a
number of test problems and several non-trivial application examples. The
User Guide can be directly invoked through Mathematica's on-line help system.

MathOptimizer Licensing

In addition to professional licenses, fully functional MathOptimizer
versions with educational and non-profit research discounts are offered to
professors and their student groups, and to qualifying researchers.
Individual instructor and student licenses, department and site licenses
are also available. Professional users are also entitled to quantity
discounts.

Subject: Conference in Nijmegen on Preconditioning

First announcement of a Conference on

PRECONDITIONING METHODS FOR OPTIMAL CONTROL
AND CONSTRAINED OPTIMIZATION PROBLEMS (PMOCCO 2002)

to be held at the University of Nijmegen, Nijmegen, The Netherlands
October 24-26, 2002

A conference devoted to preconditioning methods for constrained optimization
and optimal control will be held. Problems of this type arise in applications
of quite different origin, such as in natural sciences, in optimal design
in engineering, in medical applications such as tomography, in economics etc.

The problems must in general be solved by some iterative solution method.
Thereby it is important to use an efficient preconditioning method for the
arising linear or nonlinear systems of algebraic equations, which are
typically of indefinite (symmetric or nonsymmetric) saddle point type.

The conference aims at bringing together scientists working in the theoretical
development of preconditioning methods and scientists working with applied
problems. It will focus on the above mentioned particular topics but other
related topics such as LBB stable element pairs, stabilization methods,
adaptive mesh refinements, optimal mesh design, and mortar element methods,
may also be presented.
