Once the package has been downloaded and unzipped, two example problems can be tested with make_f77.bat and make_f95.bat batch files.  These batch files compile the hs071 Fortran examples and link them to the IPOPT library to form ''ipopt.exe''.  The batch file then runs the ''ipopt.exe'' program

!!! IPOPT for AMPL

[[https://www.ampl.com | AMPL]] is a comprehensive and powerful algebraic modeling language for linear and nonlinear optimization problems, in discrete or continuous variables.  Developed at Bell Laboratories, AMPL lets you use common notation and familiar concepts to formulate optimization models and examine solutions, while the computer manages communication with an appropriate solver.  AMPL's flexibility and convenience render it ideal for rapid prototyping and model development, while its speed and control options make it an especially efficient choice for repeated production runs.  A [[https://www.ampl.com/DOWNLOADS/details.html#WinStd | student version of AMPL]] can be obtained at the AMPL website.

This IPOPT executable uses [[MUMPS | https://mumps.enseeiht.fr/]], a parallel sparse direct solver.

!! IPOPT

IPOPT or  'Interior Point Optimizer' is a large-scale nonlinear programming (NLP) solver.  It is part of the the COIN-OR open-source effort for the development of solvers for problems in the field of operations research.  There are various repositories that contain binaries of IPOPT for a variety of operating systems and compilers.

This page contains an IPOPT compiled library for use on Windows (32-bit) computers.  The zip archive also contains the g95 (v0.9) Fortran compiler, compatible with gcc (v4.0.3).  The package contains all files necessary to run the IPOPT solver.

Attach:ipopt_files.png

Once the package has been downloaded and unzipped, two example problems can be tested with make_f77.bat and make_f95.bat batch files.  These batch files compile the hs071 Fortran examples and link them to the IPOPT library to form ''ipopt.exe''.  The batch file then runs the ''ipopt.exe'' program.
