Print model? #20

Closed stevenshack closed 3 years ago

stevenshack commented 3 years ago

In the or-tools c++ interface there is solver.ExportModelAsLpFormat to print out model details. This would be useful for debug purposes if it were exposed on ruby land. BTW thanks for the good work on this project.

Hey @stevenshack, thanks for the suggestion! Added in the commit above.

No problem. Is there an equivalent for VRP? I actually thought the VRP code was using a linear solver under the hood.

Not that I'm aware of. OR-Tools routing code uses the CP solver.
