26 Dec '12

Dear colleagues, I would appreciate if you could distribute this announcement through your mail list. Best, Emilio Carrizosa ****************************************************** SPECIAL ISSUE ON VARIABLE NEIGHBORHOOD SEARCH ****************************************************** JOURNAL OF GLOBAL OPTIMIZATION www.springer.com/10898 2011 Impact Factor 1.196 ****************************************************** Variable Neighborhood Search (VNS) is a metaheuristic which has shown to be very successful for solving hard combinatorial and global optimization problems. During the EURO Mini-Conference on VNS took place in Herceg Novi, Montenegro, October 4th-7th 2012, researchers all around the world presented their most recent findings on VNS, either from a methodological viewpoint or as applications to real world problems. Authors of papers presented at the EURO Mini-Conference on VNS are especially encouraged to submit their work to this special issue in the Journal of Global Optimization. However, the issue is open to all researchers who can contribute to a better knowledge of VNS. Potential topics include, but are not limited to: Theory and Methodology: * Theoretical or empirical analysis of VNS * New variants of deterministic and stochastic VNS * Continuous global VNS * Mat-heuristics and VNS * Formulation space VNS * Multi-objective VNS * Parallel VNS * VNS hybrids Applications: * Mixed integer programming * Graphs, communication networks * Clustering, data mining, location * Inventory, routing, supply chains * Packing and covering * Discovery sciences * Other real world problems Before submission authors should carefully read over the journals Author Guidelines. Prospective authors should submit an electronic copy of their complete manuscript through the journal's editorial manager http://jogo.edmgr.com/ and specifying that their paper is for the special issue "SI: VNS 2012". Manuscript deadline: 31st December 2012.

Postdoc Position in Service Network Design
by Shahin Gelareh 30 Nov '12

30 Nov '12

The LGI2A, Laboratory of Computer Science and Control Systems of University of Artois (Bethune, North of France) is seeking to fill a postdoctoral position in: *“Service Network Design in Supply Chain Systems”* for a 12 month contract to be filled as soon as possible. Successful candidate will perform research on models of capacitated multi-commodity flow, routing and location and develop mathematical models and efficient solution methods for real-life industrial applications (exact methods and heuristic approaches). The salary will be around 2,000 euro per month (only roughly). The research will be carried out in the group of “Systems Optimization” of LGI2A led by Prof. Gilles Goncalves. LGI2A (www.lgi2a.univ-artois.fr/) offers a strong scientific support, a friendly environment and collaborative international environment. Several international/EU industrial/research projects at LGI2A permit students and researchers to be in the middle of research collaboration and help them to extend their network to their counterparts at other universities, academic institutes and industries to develop their future career. Several meetings and plenary seminars will offer opportunity to students and researchers to communicate and benefit from the others latest research results. Bethune is a beautiful city located at the North of France (40 minutes North of Lille) in a very calm and quiet North-Western European region. It will take 1 hour going to Brussels, 2 hour from London and 70 minutes to Paris by TGV trains. Candidates must hold a PhD degree (or about to defend within a month) or equivalent in computer science, mathematics or a related area and should have a solid knowledge of mixed integer programming, excellent programming skills, experience in decomposition methods (primal and dual), metaheuristics, and algorithms. Other skills such as knowledge in probability theory and stochastic programming are beneficial. Good communication skills and solid English writing skills are mandatory. Knowledge of French is not required, but successful candidates will be encouraged to learn some basics. Often there has been free French course offered to researchers and their family members by the University of Lille du Nord. Interested applicants should send their application containing - cover and motivation letter - curriculum vitae - copies of PhD degree or attestation of defense from university - summary of PhD thesis (English, about 1 pages) - names and email addresses of at least two referees, including the thesis adviser - candidate may choose to also provide complete thesis and any other scientific publications Applicants are invited to submit the application by respecting the deadline of 10 December 2012 to: Prof. Gilles Goncalves *Gilles.Goncalves(a)univ-artois.fr* and Dr. Shahin Gelareh *Shahin.Gelareh(a)univ-artois.fr* if you have any questions regarding the positions or your application, please do not hesitate to contact the aforementioned emails (emails should be destined to both).

Dear EWGLA members, We recently launched the EWGLA Facebook page: https://www.facebook.com/ewgla. You can "like" this page through Facebook to hear about the announcements and recent developments regarding EWGLA. All the past and upcoming EWGLA meetings are listed on the events page: https://www.facebook.com/ewgla/events. Here you can "join" the past meetings that you have attended. Once you join, you can write posts and share photos. We encourage all the members to post memories and pictures to these past events. For those of you who are not a member of Facebook, you can send your photos to ewgla-board(a)euro-online.org so that we can share them on our pages. We are especially in search of the group photos taken in all the past EWGLA meetings. It would be wonderful if the past meeting organizers can send such photos to us. In addition, we also established the EWGLA LinkedIn group on: http://www.linkedin.com/groups/EWGLA-4729361?home= <http://www.linkedin.com/groups/EWGLA-4729361?home=&gid=4729361&trk=anet_ug_ hm> &gid=4729361&trk=anet_ug_hm.
