Subject: New Book on Optimization

This is to inform you of the publication of a new paperback book on
optimization as follows:

Nazareth, J.L. (2004), An Optimization Primer: On Models, Algorithms,
and Duality, Springer-Verlag, New York, 120pgs., $29.95, ISBN 0-387-21155-1.

A brief synopsis and an abbreviated table of contents are attached.
Some additional detail can be found on the web at the Springer site (search on keywords from the title or the ISBN) or and background information at .

Feedback is welcome, and, if you like the booklet, please recommend it
to students and others as a way to open a window on optimization and
enliven standard course offerings/textbooks in the field.

Brief Synopsis of Book:

Optimization is the art, science and mathematics of finding the `best' member
of a finite or infinite set of possible choices, based on some objective
measure of the merit of each choice in the set. Three key facets of the
subject are:

* the construction of optimization models that capture the range of
available choices within a feasible set and the measure-of-merit of
any particular choice in the feasible set relative to its competitors;
* the invention and implementation of efficient algorithms for solving
optimization models;
* a mathematical principle of duality that relates optimization models
to one another in a fundamental way. Duality cuts across the entire
field of optimization and is useful, in particular, for identifying
optimality conditions, i.e., criteria that a given member of a feasible
set must satisfy in order to be an optimal solution.

This slim and inexpensive paperback provides a gentle introduction to the
above topics. It assumes very little in the way of mathematical background,
and its presentation strikes a balance between the specific details of a
representative set of models, algorithms, and their associated duality, on
the one hand, and the `big picture' of optimization as summarized by visual
schematics and associated commentary, on the other. It is aimed at college
students beginning their studies in optimization (and is also accessible to
college-bound students in science and mathematics in high schools), general
readers looking for an overall sense of the field of optimization, and
specialists in optimization interested in developing new ways of teaching
the subject to their students. In particular, it can be used as a front
end to complement and enliven any of the currently available texts in
optimization (network flows, linear and nonlinear programming) that treat
the subject more comprehensively.

Abbreviated Table of Contents:

A Quintessential Optimization Problem * Duality on Bipartite Networks *
A Network Flow Overview * Duality in Linear Programming * The Golden Age

Subject: Postdoctoral Position in Lyon


Within a collaboration with CEA (Commissariat a l'Energie Atomique) / LETI
(Laboratoire d'Electronique Technologies et Instrumentation), the INRIA
project Arenaire offers a 12 months postdoc position.

** Objectives

Last years have seen major investments in public-key cryptography research.
Indeed, new commercial cryptographic products rely on very high ciphering
speed. Also, technology evolution with always faster processors for
breaking codes leads to consider longer keys for preserving security.
These two aspects show that efficiency of cryptographic algorithms is
crucial issue nowadays. The design of hardware implementations is an
important point for providing new solutions. In collaboration with several
other groups (ACI Cryptologie ---
--- and ACI Securite Informatique ---,
one of the research directions of the Arenaire project addresses the
question with the study of hardware dedicated arithmetic operators.

The object of this postdoctoral position is to participate to these
research with the design and implementation of number representations,
associated algorithms, and cryptographic functionalities. For instance it
may concern hardware realizations, on FPGA circuits, for finite fields and
elliptic curves arithmetic in the context of ciphering or code-based
digital signature. Our long-range objective, together with the development
of an experimental platform for best software and hardware solutions
comparizon, it to offer a complete hardware demonstrator usable by any
standard computer.

** Arenaire project.

Arenaire is a project of 16 researchers which aims at elaborating and
consolidating knowledge in the field of computer arithmetic. We contribute
to the improvement of the available arithmetic, at the hardware level as
well as at the software level, on computers, processors, dedicated or
embedded chips, etc. Reliability, accuracy, and speed are major goals that
drive our studies. We also take into account other constraints such as
power consumption, certification using formal proof techniques or
reliability of numerical software. Target arithmetics are fixed or
floating point format, interval arithmetic, finite fields arithmetic and
multiple precision.

** Skills and applications

Candidates should have skills in the domain of cryptographic algorithms.
Knowledge in hardware design, for instance using VHDL for FPGAs, will be

Interested candidates should contact or send files directly to
{Arnaud.Tisserand, Gilles.Villard} as soon as possible. The
final selection should happen end September 2004. Files must contain a cv,
a brief description of research work and recommendation letters.

Subject: Studentships at the University of Wales, Aberystwyth

M.Sc. Course in Complex Fluids: Modelling, Simulation and Industrial Applications

The Institute of Mathematical and Physical Sciences at The University of
Wales Aberystwyth has funding from the EPSRC for a Masters Training Package
in Complex Fluids: Modelling, Simulation and Industrial Applications. This
is a one- year modular M.Sc. course. The study of complex fluids involves an
interdisciplinary approach, which calls upon engineering, physical chemistry
and physics as well as mathematics. An understanding of the properties and
behaviour of these fluids is important for many industrial processes.

The course is run by the Applied Mathematics Group at Aberystwyth which is
recognized for having achieved the highest international standards of
excellence in the study of complex fluids. The Group is unique in the UK in
that it offers a unified approach to the mathematical modelling, computation
and analysis of complex fluids, supported by an experimental laboratory
devoted to their characterization and analysis The Applied Mathematics Group
enjoys close contacts with Industry including a number of collaborative
research projects. The industrial relevance of the course will be monitored
by a steering group of industrialists. The training aims to equip students
with the skills they require to meet the challenge of modelling and
simulating complex fluids in scientific and industrial flow applications.
These skills are essential in many areas of science and engineering
especially with the plethora of new materials being designed, produced and
processed today.

There are small number of studentships that remain to be filled this year.
Applicants should have, or expect to gain, a good honours degree or
equivalent in mathematics or any relevant scientific discipline. There is
also provision for applicants wishing to embark on the course part-time.
