            1.   Repositories for implemented algorithms.  Informs 
                 resource collection: > 100 packages and online programs
                 1.  COIN - OR
                 2.  NEOS Server
                 3.  Specific algorithms e.g. Ye’s semidefinite opt code
            2.   Repositories for test problems.  Informs resource: 25 
                 instance sets & generators.
                 1.  DIMACS combinatorial challenge sets
                 2.  MIPLIB, LP test sets
                 3.  Problem specific sets e.g. TSP,QAP,VRPTW.
            3.   Simulation tools: relatively few, often commercial-linked
            4.   Stat tools: several libraries and web-available routines

          1.   Unified, robust algorithms. Make it the standard 
               that researchers add to the repository.  We would 
               build more on each other’s work. Quality and 
               development speed would increase.
          2.   Simulation building blocks
              1. Modeling
              2. Output analysis
              3. Parameter search
          3.   Problem testbeds and instance generators.

          1. More general modeling language, unifying 
               CP, IP/LP, NLP.

      Claim:  OR is unusual among 
        science/engineering disciplines in that the 
        applicability of present technology, as 
        perceived internally, is 10-100 times the 
        present level.
      What’s wrong?  OR is about decision making, 
        not just solving models.  Old news…
      but CyberInfrastructure could increase the 
          CyberInfrastructure
        applicability of OR by an order of 
        magnitude.
