1. COIN-OR:Introduction to the “Computational Infrastructure for Operations Research” JP Fasano Alan King Robin Lougee-Heimer Matthew Saltzman Ted Ralphs

2. EURO 2006 “What”  COIN-OR is A repository of source code, models, data, examples Available for re-use Under open-source licenses Powered by volunteers Experiment started by IBM in 2000

3. EURO 2006 What is “Open Source”?  A category of software licenses Rules by which code can be used, copied, modified, distributed,... Freely available, usually via Internet Changes typically given back  A philosophy Healthy virtual community Debugs, maintains, enhances the source

4. EURO 2006 Common “Open-Source” Misconceptions  All open-source licenses are the same E.g., Viral vs. non-viral  “Free for academic use only” is open source Discrimination  Open source is the same as freeware/shareware Binary executable to end-user software Restricted intellectual property rights

5. EURO 2006 “Why” for the community?  Reuse rather than reinvent  Fairer comparisons  Build on the best  Promote standards  Foster collaboration and cross- pollination  Outlet for software not “product destined”

6. EURO 2006 Companies & COIN-OR Industry accounts for 37 % of the coin-discuss mail list
