What LP/MIP solvers does ECLiPSe have?

ECLiPSe is able to interface with the open-source Coin-OR project’s solvers via their Open Solver Interface (OSI); currently this is mainly interfaced to the CLP/CBC solvers, with a prototype to SYMPHONY/CLP solvers. It is also able to interface to the commercial solvers ILOG’s CPLEX and Dash Optimization’s Xpress-MP, but no license for either is included with ECLiPSe 5.8 or later. Both companies offer academic licences at discounted rates. Dash offers free academic licenses to Universities through their Academic Partner Program. The interface to Xpress-MP is only up to versions of Xpress-MP developed in 2005, because the developers does not have access to later versions of the solvers. If anyone wants to continue the development of the interface, or provide access to Xpress-MP solver for development, please contact the developers via the mail list.
