AMPL Amp; CPLEX Solver Suite

AMPL & CPLEX Solver Suite: A Free and Powerful Tool for Linear and Nonlinear Optimization

If you are interested in mathematical modeling and optimization, you might have heard of AMPL and CPLEX. AMPL is a popular modeling language that allows you to express complex optimization problems in a clear and concise way. CPLEX is a well-known and widely used solver that can handle large-scale linear, quadratic, and integer optimization problems. But did you know that you can download and use AMPL & CPLEX solver suite for free? In this article, we will show you how to get AMPL & CPLEX solver suite for free and how to use it to solve your optimization problems.

What is AMPL & CPLEX Solver Suite?

AMPL & CPLEX solver suite is a combination of two powerful software tools for optimization: AMPL and CPLEX.

AMPL stands for A Mathematical Programming Language. It is a high-level language that lets you formulate optimization problems using algebraic expressions, logical constraints, data tables, and sets. AMPL supports various types of optimization problems, such as linear, nonlinear, integer, network, stochastic, and multi-objective. AMPL also allows you to connect to different solvers, such as CPLEX, to find optimal or near-optimal solutions.

CPLEX stands for C Programming Language Extended. It is a solver developed by IBM that can solve large-scale optimization problems involving linear, quadratic, or integer variables. CPLEX uses advanced algorithms and techniques, such as simplex, interior-point, barrier, branch-and-bound, presolve, heuristics, and cut generators. CPLEX also supports parallel processing, concurrent optimization, parameter tuning, and infeasibility diagnosis.

AMPL & CPLEX solver suite is a package that includes both AMPL and CPLEX software. You can use AMPL to model your optimization problem and then use CPLEX to solve it. You can also use AMPL to access other features of CPLEX, such as indicator constraints, convex quadratic expressions and constraints, and constraint programming.

How to Download AMPL & CPLEX Solver Suite for Free?

To download AMPL & CPLEX solver suite for free, you need to follow these steps:

  • Go to the website of All Solvers for AMPL. This is a page that provides a list of solvers that are compatible with AMPL and links to further information.

  • Scroll down to the table and find the row that says "CPLEX". Click on the link that says "Try with AMPL". This will take you to another page where you can request a free trial of AMPL & CPLEX solver suite.

  • Fill out the form with your name, email address, organization name, country, and purpose of use. Agree to the terms and conditions and click on "Submit".

  • You will receive an email with a link to download AMPL & CPLEX solver suite. Click on the link and save the zip file to your computer.

  • Extract the zip file to a folder on your computer. You will see two subfolders: one for AMPL and one for CPLEX.

How to Use AMPL & CPLEX Solver Suite for Free?

To use AMPL & CPLEX solver suite for free, you need to follow these steps:

  • Open the folder where you extracted the zip file and go to the subfolder for AMPL. You will see several files with different extensions. The most important ones are:

  • "ampl.exe": This is the executable file for AMPL.

  • "amplcml.lic": This is the license file for AMPL.

  • "amplcml.dat": This is the data file for AMPL.

  • "amplcml.mod": This is the model file for AMPL.

  • To run AMPL, you need to open a command prompt window and navigate to the folder where "ampl.exe" is located. Then type "ampl" and press enter. You will see a prompt that says "ampl:".

To load your model file into AMPL, type "model amplcml.mod;" and press enter. You will see a message that says "model e3ff22d237
