The Organizers of the XIII International Conference on Stochastic Programming (ICSP2013) are honoured to host the tri-annual Conference in Bergamo, Italy, from July 8 to July 12, 2013. The ICSP is organized by COSP, the Committee on Stochastic Programming, a technical section of the Mathematical Optimization Society. The conference aims to bring together the leading researchers in Stochastic Programming as well as academic colleagues from neighbor scientific areas, practitioners in the industrial and institutional sectors, doctoral students to share recent theoretical and applied results and push forward the state-of-the-art in this field. On July 6 and 7, a two-day introductory series of Tutorials precedes the main conference to provide sufficient background in Stochastic Programming.
