Is there a way to use another solver?

[erelsgl]

I would like to use mip with MOSEK or XPRESS, instead of CBC or GUROBI. Is it possible?

For "normal" use of the mip library, each solver needs their own implementation of the Solver interface.

As a work-around (for experiments), one option would be to create the model with Cbc, then write the problem to a file (.lp or .mps) and load that file with another solver.
