Ettore Majorana Centre for Scientific Culture

International School of Mathematics  ``G. Stampacchia''

Erice, Italy



June 30 - July 8, 2001


The Workshop is sponsored by: Italian Ministry of University and Scientific Research, Sicilian Regional Government, University of Rome  ``La Sapienza''.


In the first year of a new century, the Workshop aims to assess the past and to discuss the future of Nonlinear Optimization. Recent achievements and promising research trends will be highlighted. Algorithmic and high performance software aspects will be emphasized, along with theoretical advances and new computational experiences. Contributions from different and complementary standpoints, covering several fields of numerical optimization and its applications are expected.


Topics include, but are not limited to,

Constrained and unconstrained optimization
Global optimization
Derivative-free methods
Interior point techniques for nonlinear programming
Large scale optimization
Linear and nonlinear complementarity problems
Nonsmooth optimization
Neural networks and optimization
Applications of nonlinear optimization


As usual, the Workshop will consist of invited lectures (1 hour) and contributed lectures (1/2 hour). The following is the list of invited lecturers and the title of their talk:

Edited proceedings including the invited lectures and a selection of contributed lectures will be published by Kluwer Academic Publishers in the series Applied Optimization


The Workshop will be held at the ``Ettore Majorana'' International Centre for Scientific Culture , Erice, Italy. The Centre is situated in the old pre-mediaeval city of Erice and the lecture halls are located in two restored monasteries and the ancient Palazzo Ventimiglia - former residence of the Viceroys of Sicily.


Persons wishing to attend the Workshop should write to:

Professor Gianni Di Pillo
Università di Roma ``La Sapienza''
via Buonarroti 12
00185 Roma, Italy.

If they want to contribute a lecture, they should also include title and abstract of the proposed lecture.

Application form for participants

The total fee  is Euro 800. It includes local transportations, lodging and full board (arranged by the Centre), coffee breaks, one day excursion, social dinner and other social events. Due to the limited number of beds in Erice - a very ancient village - participants are kindly stimulated to share the room, indicating the partner; a single room will have an extra charge of 10%. The fee for accompanying  person is Euro 400.

Closing date for application: April 30, 2001
Application by e-mail is strongly encouraged.

A limited number of places is available. If necessary, admission to the Workshop will be decided by the Advisory Committee of the School composed of Professors F. Giannessi, G. Di Pillo, A. Murli  with the consultation of the invited   lecturers. Admission will be communicated shortly after the closing date for application.

Participants are expected to arrive in Erice on June 30, and to leave on July 8.


Erice is situated in the north-west corner of Sicily, in the south of Italy. The easiest way to reach it is either via Palermo or via Trapani. The Majorana Centre will then provide transportation to Erice from Palermo or Trapani airports, seaports or railway stations. More details will be given to admitted applicants.
