How to Install and Use AMPL 64 Bit on Your Computer
AMPL is a powerful and expressive modeling language for optimization problems. It allows you to formulate complex mathematical models in a natural and concise way, and to solve them using various solvers. AMPL can handle linear, nonlinear, integer, and constraint programming problems, as well as global optimization and stochastic programming.
If you want to use AMPL on your computer, you need to download and install the appropriate bundle for your operating system. AMPL supports all widely used versions of Windows, Linux and macOS. It also offers an Integrated Development Environment (IDE) that provides a convenient interface for editing, running, and debugging AMPL models and commands.
In this article, we will show you how to install and use AMPL 64 bit on your computer, and how to access some of the free open-source solvers that are compatible with AMPL.
Step 1: Download AMPL 64 Bit Bundle
To download AMPL 64 bit bundle, you need to create an account or login to the AMPL License Portal. There, you can choose from different license options, depending on your needs and preferences. For example, you can get a free Community Edition license that allows you to use AMPL with all open-source solvers, or a 30-day full trial license that includes all commercial solvers as well.
Once you select a license option, you will see a list of available bundles for different operating systems. Choose the one that matches your system (e.g., Windows 64 bit) and click on the download button. You will get a zip file that contains the AMPL program, the IDE, and the solvers.
Step 2: Install AMPL 64 Bit Bundle
To install AMPL 64 bit bundle, you need to unzip the downloaded file and copy the contents to a folder of your choice. For example, you can create a folder named "AMPL" in your C: drive and copy the files there. You don't need to run any installer or setup program.
To start the AMPL IDE, go to the folder where you copied the files and look for a program named amplide.exe (under Windows) or amplide (under Linux or macOS). The program will have a black cat's-head icon. Double-click the program file to start the AMPL IDE under Windows or macOS; use the command ./amplide to start the AMPL IDE under Linux.
Step 3: Use AMPL 64 Bit Bundle
To use AMPL 64 bit bundle, you need to write or load an AMPL model file (.mod) and an optional data file (.dat). You can use the IDE's editor window to create or edit these files, or use any other text editor of your choice. The IDE's editor window has syntax highlighting for model and data files, and quick links to error locations.
Once you have a model file and a data file ready, you can run them using the IDE's command window. The command window allows you to type commands at an AMPL prompt in the usual way. For example, you can use the "model" command to load a model file, the "data" command to load a data file, the "option" command to set solver options, the "solve" command to solve the problem using a solver of your choice, and the "display" command to show the results.
All installed solvers can be accessed directly through the IDE. You can specify which solver you want to use by typing its name after the "option solver" command. For example, if you want to use CBC (an open-source mixed-integer linear programming solver), you can type "option solver cbc;" before solving your problem. You can also use other solvers such as Ipopt (an open-source nonlinear programming solver), Bonmin (an open-source mixed-integer nonlinear programming solver), Couenne (an open-source global optimization solver), or Choco (an open-source constraint programming solver).
