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

  2. “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. 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. 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. “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. Companies & COIN-OR Industry accounts for 37 % of the coin-discuss mail list

  7. Universities & COIN-OR • Brunel • Carl von Ossietzky University, Oldenburg • Carnegie Mellon • Clemson • Cornell • Konrad-Zuse-Zentrum für Informationstechnik Berlin • Lehigh • Northwestern • Politecnico di Milano • Rutgers • Simon Fraser University • Universite de Geneve • U of Arizona • U of Pittsburgh • U of São Paulo • U of Washington • U of Waterloo • ….

  8. Current Status • COIN-OR Foundation, Inc • Educational non-profit corporation • Established 2004 • Hosted by • True community ownership • Milestone accomplishment • IBM is participating and supporting • COIN-OR is more open

  9. COIN-OR Projects – includes… COIN Branch and Cut Open Tabu Search Branch-Cut-Price Framework Open Solver Interfaces Abstract Library For Parallel Search Non-Linear Programming API Stochastic Modeling Interface COIN LP Solver Derivative-Free Optimization Manifold computation Dynamic Simplex Algorithm C++Automatic Differentiation Interior Point OPTimizer for General NLPs Cut Generation Library VOLume Algorithm

  10. Using COIN-OR • www.coin-or.org • Tarballs, binaries, Subversion and CVS • NEOS • CLP • CBC • DFO • IPOPT • Products • E.g, Frontline Systems and Knitro • Support • Free • E.g, coin-discuss@list.coin-or.org • Buy
