Quick Roadmap

If you want to:

• Download the OS source code - see Section 3.

• Build the OS project from the source code - see Section 4.

• Use the OS library to build model instances or use solver APIs - see Sections 7.3, 7.5, and 8.

• Use the OSSolverService to read files in nl, OSiL, or MPS format and call a solver locally or remotely - see Section 10.

• Use AMPL to solve problems either locally or remotely with a COIN-OR solver, Cplex, GLPK, Knitro, or LINDO - see Section 12.1.

• Build a remote solver service using Apache Tomcat - see Section 11.

• Use MATLAB to generate problem instances in OSiL format and call a solver either remotely or locally - see Section 7.3.3.

• Use the OS library for algorithmic differentiation (in conjunction with COIN-OR CppAD) - see Section 9.

The OS project is very extensive and relies on many other COIN-OR projects. This may not be desirable for modeling language and solver developers that just wish to use the OS API in conjunction with their modeling language or solver. Hence there is also an ``OS lite'' download that consists of all the code for the OS API and for reading and writing instance and solution files. We refer to this version of the project as OSCommon and the code for this project is synched with the corresponding stable and release versions of the code. For example, to get Stable 1.1 of OSCommon use the svn command

svn co https://projects.coin-or.org/svn/OS/stable/OSCommon1.1  OSCommon
