Subject: Recent Survey of Unconstrained Optimization

I would be interested in recent literature on fast optimation techniques,
for very large numbers of variables.  Either literature on recent
progress in using conjugate gradient techniques preferably preconditioned or
one of the truncated Limited Memory Quasi Newton methods would be
appreciated.

  Topics

  Parallel architectures

  The course will present an overview on parallel architectures in general
  with special focus on parallel machines with distributed memory.
  Strong and weak points of the different types of architectures are critically
  discussed and compared. Software development environments and tools for
  parallel architectures are presented and the importance of these tools for
  the strongly application oriented user is explained. Models describing
  the performance of parallel architectures with shared and distributed
  memory architectures are discussed.

  Software development strategies for parallel architectures
  
  After presenting an introduction to numerical modelization in general,
  the course will discuss the different phases, starting from real experiment,
  switching to physical and numerical modeling. Special focus is on the
  adaptation of numerical approaches to modern parallel architectures.

  Neural networks
 
  The course will describe the current state-of-the-art in neural computing.
  It will not assume prior expertise in neural networks. The six lessons
  presented will cover machine learning and biological computation, learning
  rules and implementations for adaptive artificial neurons, neural network
  systems, applications like pattern recognition and signal processing, and
  a review of existing software design tools, hardware implementations, neural
  network journals, books, and conferences.

  Applications
  
  A major fraction of the course is dedicated to the presentation of the
  successful implementation of a broad spectrum of applications drawn from
  physics, engineering, computer science and other areas. The usefulness of
  the distinct types of parallel architectures for a collection of very
  CPU-intensive applications is compared, and, depending on the type of
  architecture, concrete techniques are presented, by means of which these
  applications can be mapped to the hardware in an optimal fashion.

  Organization
 
  During the five days of the course, there will be six hours of lectures
  each day, supplemented by informal discussion sessions during the day and
  in the evening. A detailed program and abstracts of the lectures will be
  issued to those attending. The full collection of the written versions of
  the lectures will become available at the time of the summer course. The
  proceedings will be published in a special issue of   Computer Physics
  Reports.
