Breakfast Meetings


Breakfast meetings are informal meetings where there is a general discussion or someone presents their work. And additional goal is to have breakfast together.


  1. Send an email to the responsible of Optimization Meetings. Mention your name, your affiliation, the date, time and room, and a short summary of what you are going to talk about.
  2. Add a new entry to the table below.
  3. Bring breakfast.

History of Breakfast Meetings

Date Presenter Summary
2010-05-20 Marco Montes The social learning strategies tournament, organized as part of the

2010-05-?? Renaud Lenne  ???
2010-04-29 Franco Mascia The maximum clique problem, state of the art and ACO [1] [2] [3]
2010-03-18 Sabrina Oliveira Achieved results from the application of the Population Based Ant Colony Optimisation algorithm to TSP.
2010-02-11 Sara Ceschia An overview of Container Loading Problems.
2010-01-21 Yuan, Zhi (Eric) Rice cooker vs. the idea of tuning.
2010-01-07 Thomas Stüztle General discussion about the optimization group.

Literature Sessions


The goal of the Literature Sessions is to examine and discuss particularly interesting papers from the research literature. For each session, one paper will be selected, there will be a short presentation (10-15 minutes) about the contents, and a discussion will ensue. Sessions will last around 40-45 minutes. Attendants should read the paper before the session in order to have a productive discussion.


  1. Book a room (ask Muriel).
  2. Send an email to the responsible of Optimization Meetings. Mention your name, your affiliation, the date, time and room, a reference to the paper and the URL where it can be obtained. Also, attach the paper in PDF.
  3. Add a new entry to the table below. Please add a complete bibliographic reference (you may find it in the homepages of the authors) and a hyperlink to a PDF (links to http://dx.doi.org are preferred).
