AMPLPY-XPRESS

XPRESS driver for AMPL. This package uses AMPLS-API, which is an open source set of lightweight interfaces between AMPL and solvers, which allow:

• Read in an AMPL model instance from an NL file
• Write out the solution as a sol file, ready to be imported by AMPL
• A choiche between:
  • Use of all the solver's capabilities, using its own C API functionalities
  • Use of a (provided) generic interface, that encapsulates the most common functionalities of the solver interfaces, permitting hassle-free solver swap
• Usage of existing AMPL licenses, when used together with the AMPL drivers

The interfaces are available for multiple languages; the core is written in C++ and it is wrapped using swig to other target languages.
