CPLEX for AMPL IBM ILOG CPLEX is the best known and most widely used large-scale solver. Its efficiency and robustness have been demonstrated over two decades in thousands of commercial installations worldwide. Summary Developer: IBM ILOG Current version: 20.1 Problem. Version 12.9 of IBM ILOG CPLEX Optimization Studio July 01, 2019. IBM ILOG CPLEX Optimization Studio Version 12.9 is now available on Passport Advantage for commercial users, through the Academic Initiative program for academics and students, and as a trial. The mathematical programming technology of CPLEX Optimizer enables decision optimization for improving efficiency, reducing costs and increasing profitability. CPLEX Optimizer provides flexible, high-performance mathematical programming solvers for linear programming, mixed integer programming, quadratic programming and quadratically.

In this tutorial I will describe how to download and install a full version of IBM ILOG CPLEX Optimization Studio 12.6.1 (the latest version as of now – May 2015).

IBM gives scholars and university researchers free access to its software and systems. This support to our academic research is greatly appreciated. You need to register and apply for the IBM Academic Initiative program, through IBM Academic Initiative.

When you receive the confirmation of your eligibility, you can login and click on “Access IBM software and systems”, which will allow you to search for whatever IBM product you want. Here, I was looking for “CPLEX”. A list of CPLEX versions appears in the pop-up list, I clicked on CPLEX 12.6.1, the latest one.

Then a large list of supported platforms appear. I downloaded the 784MB for Windows 64 bits. Then it is as easy as executing the downloaded file.

Go through the regular installation options and click Next.

In the end you will have installed a full version of CPLEX Optimization Studio. Enjoy!

Downloading the
CPLEX 8.0 Student Edition
for AMPL

For current AMPL users

Download Cplex For Matlab

Current AMPL users can now download an AMPLstudent edition of the new version 8.0 of CPLEX. Like other AMPLstudent editions, this AMPL/CPLEX is full-featured but limited to 300variables and 300 objectives plus constraints. It includes the CPLEXcomponents that solve

linear and convex quadratic programs by simplex methods
linear and convex quadratic programs by interior-point methods
linear and convex quadratic integer programs by a branch-and-boundprocedure

If you are a current user of standard (command-line)AMPL, follow our CPLEX 8.0 downloadinstructions below. You may want to also get the latest AMPLversion by following our AMPL downloadinstructions, but this is not necessary.

If you are a Windows user new to AMPL, take a look at our quick start instructions given below. You can get theStudent Editions of both standard AMPL and CPLEX 8.0 by downloading andunpacking a single zip archive file.

If you are a Unix or Linux user new to AMPL, consult our Unix download instructions to obtain anappropriate copy of the AMPL Student Edition. Then download CPLEX 8.0 by following the instructionshere.

If you are an AMPL Plus user orneed a size-unrestricted version of CPLEX, see our notes on obtainingother AMPL/CPLEX versions.

Downloading the CPLEX 8.0 Student Edition
for current users of command-line AMPL

The CPLEX 8.0 studentedition for AMPL is available for download for the followingplatforms:

DEC(Compaq) Alpha workstations running OSF/1 v2.0
IBM PowerPCworkstations running AIX
Intel (Pentium-compatible) PCs running Windowsor Linux
SiliconGraphics workstations running IRIX 5.x or 6.x
SunMicrosystems SPARC-based workstations running Solaris 2.5.1 (SunOS5.5.1) or later

To install, click on the appropriate link above, and then proceed as follows:

For Windows, you will obtain the zip archive file cplex.zip. If your web browser doesn't automatically unpack this archive,double-click on the cplex.zip file icon to unpack it. Theunpacking procedure should produce two executable files, cplex.exe and cplex80.dll, which are both required to run the CPLEX 8.0 solver. (If you can't get thearchive to unpack, your computer lacks a properly configuredzip-file utility. You can download a program such as UnZip, WinZip, or StuffitExpander to unpack zip files.)
For Unix/Linux, you will obtain the compressed tar archivefile cplex.tgz. Decompress bygzip to create an archive named cplex.tar, thenunpack this archive by use of the command tarxvfcplex.tar to obtain the file cplex.

Place the CPLEX executable file or files in the same folder ordirectory as your AMPL executable, or anywhere in your search path. Itwill then be accessible from AMPL by giving an AMPL command of the formoptionsolvercplex beforesolve.

A license agreement for CPLEX 8.0 appears in a file that is alsounpacked by the above procedures. For detailed instructions on usingCPLEX from AMPL, including a complete listing of CPLEX options anddirectives, consult the ILOGAMPL CPLEX System Version 8.0 User's Guide.

Downloading the CPLEX 8.0 Student Edition
for Windows users new to AMPL

For a quick start if you haven't yet acquired either AMPL or CPLEX, start by downloadingchapter 1 of the AMPLbook. Then download the command-line AMPL zip archive file:If your web browser doesn't automatically unpack this archive,double-click on the amplcml.zip file icon to unpack it.(If you can't get the archive to unpack, your computer lacks aproperly configured zip-file utility. You can download a programsuch as UnZip, WinZip, or StuffitExpander to unpack zip files.)

The unpacking procedure should create a folder named amplcmlcontaining the standard AMPL program (ampl.exe), the scrolling-window utility(sw.exe), and an executables for CPLEX 8.0 (cplex.exeand cplex80.dll). You may move and rename theamplcml folder to whatever is convenient for you. (Also inthis folder you will find files for the Kestrel internet optimizationclient and the AMPL database handlerfor Windows, which you may choose to investigate.)

To run AMPL and CPLEX using these files, double-click onsw.exe, and in the window that appears, type ampl toload the AMPL program. At this point the window should show thefollowing,

and you can proceed to enter commands at the 'ampl:' promptsas shown in the AMPL book. To select CPLEX as your solver, enter thecommand optionsolvercplex; before the firstsolve of your AMPL session. Finally, to get test problems andsample models from the AMPL book and elsewhere, consult our AMPL examples page.

Other AMPL/CPLEX versions

A student edition of CPLEX 6.5.3 was part of the the AMPL Plus Student Edition 1.6, includedon CD with copies of the AMPL book fromearly 2000 onward. AMPL Plus is not currently being maintained,however, and its CPLEX-based license will expire on January 1, 2003.Thus AMPL Plus users will need to switch to analternative AMPL version before the end of 2002.Currently it is possible to download any of several the experimental GUIs, as well as the standard AMPL based on a command-lineinterface. New GUIs for AMPL are under consideration and will beannounced as they become available.

Unrestricted versions of AMPL with CPLEX areavailable from ILOG, Inc. Further information may be obtained bysubmitting ILOG's WebInformation Request Form, writing to info@ilog.com, or calling +1800-FOR-ILOG (+1 800-367-4564) or +1 775-831-7744.
