From dmanet@math.utwente.nl Tue Apr 27 02:06:54 1999 Date: Tue, 27 Apr 1999 10:43:29 +0200 From: Discrete Mathematics and Algorithms Network Reply-To: zhang@few.eur.nl To: DMA-LIST@NIC.SURFNET.NL Subject: HPOPT99 (second announcement) ######################################### S E C O N D A N N O U N C E M E N T ######################################### Fourth workshop on High Performance Optimization Techniques (HPOPT'99) Wednesday, June 16, 1999 to Friday, June 18, 1999 To be held at World Trade Center, Rotterdam - The Netherlands ==> including a one-day tutorial on <== ==> mathematical foundations of optimization <== ******************* Aim of the workshop ******************* HPOPT'99 will take place in the context of the Dutch research project 'High Performance Methods for Mathematical Optimization'. In this project, funded by the Dutch Organization for Scientific Research (NWO), research teams cooperate from four universities in the Netherlands: TU Delft, Erasmus University, TU Eindhoven and University of Utrecht. In the project we focus on duality, algorithms, complexity, sensitivity and numerical aspects and we strive to touch each of these aspects in the workshop. The goal of the workshop is twofold. * The first day (Wednesday) of the workshop consists of a number of tutorials on mathematical foundations of optimization, including semidefinite programming (SDP). The basic principles of SDP will be explained as well. State-of-the-art implementations of IPM for SDP will be discussed. This day is meant for researchers and/or Ph.D students with a background in applied mathematics, operations research, or quantitative economics. It will be useful for university lecturers interested in presenting courses in this new area. * During the remaining two days, the goal is to bring together some of the most active researchers working in this and related areas; to exchange ideas and research plans and to discuss future developments in the field. There is still some, but limited, room for contributed talks. Submissions are possible till April 30, 1999. ************************************* Main invited speakers at the workshop ************************************* J.
