Title: Recent Developments in COIN-OR
Chair: Jeff Linderoth, Lehigh University,
  • Title: CoinMP: Simple C-API Windows DLL implementation of CLP, CBC, and CGL

    Lead: Bjarni Kristjansson , Maximal Software, Inc
    Abstract: The COIN Open Source Initiative has become very popular in the recent years. To make life easier for users that simply want to solve models and not compile C++ applications, we have developed standard C-API Windows DLL CoinMP.DLL that implements most of the functionality of CLP, CBC, and CGL.

  • Title: How to Publish Your Code on COIN-OR

    Lead: Robin Lougee-Heimer, IBM Research,
    Abstract: We review the processes and decisions involved in contributing to a COIN-OR project or "publishing" your own open-source code, data, and models in the COIN-OR repository. Common misconceptions regarding licenses, code ownership, and open-source will be discussed and your questions discussed.

  • Title: Experiences with NLPAPI

    Lead: Jeff Linderoth , Lehigh University,
    Abstract: NLPAPI is provides a way to create Nonlinear Programs, solve them, and access their solution information. In this talk, we will give some examples of using NLPAPI in the context of building solvers for nonconvex quadratc programming and mixed integer nonlinear programming.

Title: Using Cyberinfrastructure for Computational Operations Research
Chair: Robin Lougee-Heimer, IBM Research,
  • Title: Using Cyberinfrastructure for Computational Operations Research

    Lead: Jeff Linderoth, Lehigh University,
    Abstract: Cyberinfrastructure describes the melding of tools and capabilities ---hardware, middleware, software applications, algorithms, and networking--- that are now transforming research and education. In this talk, I will give a survey of cyberinfrastructure tools available for operations research professionals, with an emphasis on optimization tools. The talk will conclude with two case studies demonstrating the successful application of cyberinfrastructure in solving large-scale instances of optimization problems.
