Xpress-MP software interfaces

Xpress-Optimizer, Xpress-BCL, Xpress-Mosel and Xpress-SLP are available as libraries, enabling the developer to embed the full power of Xpress-MP within their application. The range of functionality is vast: the most basic functionality allows the developer to define a problem, solve it, and examine the solution, all within their application code. More advanced functionality enables the developer to control and tune the optimization algorithms, manipulate the problem after it has been solved, building up optimization heuristics and techniques, and handle multiple problems in different threads. At the lowest level, the developer can declare callback functions to interact with the Xpress-Optimizer during the MIP optimization process, to generate cutting planes and implement their own branching strategies.

Several programming interfaces are available, among them C, C++, Java, VB and .NET.

The Xpress-Optimizer, Xpress-Mosel and Xpress-SLP are also available in console form, that is, stand alone executables controlled using simple text driven interfaces. They have low overhead and development requirements, and offer a straightforward means to get simple batch-driven applications up and running with the minimum of effort.
