OS

The Optimization Services (OS) is one of the COIN OR projects. OS provides a set of XML-based standards for representing optimization instances (OSiL), optimization results (OSrL), optimization solver options (OSoL), and provides a framework for communication between clients and solvers in a distributed environment using Web Services.

The OS project directly supports the following solvers:

• Bonmin
• Cbc
• Clp
• Cplex
• DyLP
• Glpk
• Ipopt
• Lindo
• SYMPHONY
• Vol

If we hook ASCEND to OS and produce OSiL instances for the models written in ASCEND we would be able to take advantage of the solvers supported by OS and also of next generation distributed optimization systems, mainly optimization over the Internet.
