LANCS International Workshop on
Discrete and Nonlinear Optimisation
Cardiff, 13th-15th May 2013
The conference booklet, with programme and abstracts, can be found here.
Purpose and Scope
LANCS is a consortium of Operational Research groups from four British universities. This workshop, which was organised by the LANCS Optimisation Research Cluster, focused on discrete and nonlinear optimisation. Historically, there has been a fruitful interaction between these two fields, which methods from one branch being applied to problems in the other. The purpose of the workshop was to facilitate further interaction of this kind.Location and Date
The workshop took place in the Mathematics Institute, Senghennydd Road, Cardiff. The workshop began on Monday 13th May 2013 in the morning, and finished on Wednesday 15th around lunchtime.Organizers:
The organizers were Iskander Aliev (Cardiff), Joerg Fliege (Southampton) and Adam N. Letchford (Lancaster).Invited Presentations:
- Immanuel Bomze (Vienna): A nasty cone with nice properties - new issues in copositive optimization
