ISCO 2014 and Spring School in Stochastic Programming (2nd announcement) The 3rd International Symposium in Combinatorial Optimization (ISCO 2014) will take place in Lisbon, March 5-7 2014, in Campo Grande, Lisboa, Portugal. ISCO is a biannual symposium whose aim is to gather researchers from combinatorial optimization and other related fields of operations research. Conference Chairs: Luis Gouveia (Univ of Lisbon-CIO) and Ridha Mahjoub (University Paris-Dauphine) Plenary Speakers: Matteo Fischetti (Univ. of Padova), Martin Grotschel (ZIB-Berlin) and Adam Letchford (University of Lancaster) Abstract submission deadline: December 15, 2013 Accepted regular papers (with up to 12 pages) will be published by Springer-Verlag in the Lecture Notes in Computer Science (LNCS) series in a post-conference proceedings volume. The authors will have to prepare their camera-ready version two weeks after the end of ISCO 2014. A special issue of Discrete Optimization on "Combinatorial Optimization" will be associated to ISCO2014 This symposium is preceded by a spring school titled "Stochastic Programs with Integer Variables: Theory, Algorithms, and Applications" School lecturers - Rüdiger Schultz (University of Duisburg) and Jonas Schweiger (ZIB-Berlin) For more information on the Symposium and School, see ISCO2014.fc.ul.pt. The 12th INFORMS Telecommunications Conference (2014) will also be held from the 2nd to the 4th of March, just before ISCO 2014, also at Campo Grande, Lisbon. See the registration (to be updated) for reduced fees for people attending the two conferences.
