[Feature request] Writing a problem to the AMPL format

[malipivo]

Hello,

Thank you for Scip, it is a lot of fun! It would be nice to be able to write problem to the AMPL format (.mod, .dat). https://ampl.com/ After that, it would be possible to test commercial solvers via the NEOS server (e.g. in the MILP section).

Thank you for considering it! Best regards, Pavel

If you just need MILP, then write the problem as MPS. This seems to be supported by most solvers in the MILP section of NEOS.
Also for quadratic nonlinear constraints, MPS should be viable.

For more general nonlinear, you could try with the GAMS writer. The CONVERT application at NEOS can also translate GAMS to AMPL.
