FICO Xpress Optimization [1] is a software suite for developing and deploying optimization models. It comprises a set of solvers, including linear, mixed-integer, and various nonlinear solvers as well as a constraint programming solver. Users have the flexibility to choose among several options for formulating their optimization models : direct interfaces to the solver libraries are available for several programming languages such as C, Java, .NET, Python, R. Alternatively, the user can opt to work with an algebraic modelling language, most prominently Xpress Mosel [2], a free software (see also [3]) that forms part of the Xpress suite and that provides access to all solvers of the Xpress suite, including a robust optimization module that is only available through Mosel. Third party modelling tools, such as AMPL or GAMS equally provide interfaces to certain Xpress solvers.
