[Ipopt] C++ interface and .nl files

[Horand Gassmann]

This is actually not true. David Gay made available and maintains the AMPL Solver Library ASL, which can be downloaded from COIN-OR. The OS project has an interface to Ipopt that uses ASL and provides support for .nl files, even if Ipopt does not do so directly.

Short answer is NO.

You should look into modeling tools like Pyomo or Casadi. You can find
examples in each respective package.
