Having done so will be able to see two links (Download v12.8 or Download v12.9) in section ILOG CPLEX Optimization Studio. Click on one of them and choose the distribution you need. Hope it helps:-). CPLEX 12.5: mean = 252.4; median = 127.0; standard deviation = 360.0 CPLEX 12.8: mean = 256.7; median = 129.5; standard deviation = 351.8 There were only 4 out of 32.sav files in which CPLEX 12.8 took less time than CPLEX 12.5. If you installed cplex in a non default folder (or if you are using the community version) please make sure, that you create an environment variable ILOGCPLEXPATH pointing to the directory containing the CPLEX.
This guide describes a quick and easy way to install the product.

Product overview
CPLEX Solution Polishing¶. Also the solution polishing heuristic of CPLEX is available in AIMMS to boost performance on certain types of models. Solution Polishing is appropriate for finding the best solutions to complex and difficult Mixed Integer Programming models within a specified time and is used to improve the best solution at the end of the branch-and-cut process if optimality has not. I recommend you use download director (default) and not http as it is more robust. Select the latest CPLEX version (12.6 in the picture below), then select the image that fits the operating system of your.
IBM® ILOG® CPLEX® Optimization Studio offers rapid development anddeployment of optimization models through debugging, testing, tuning and application generation.
CPLEX Optimization Studio provides the most efficient wayto build optimization and constraint programming models for planning and scheduling. With itsintegrated development environment (IDE), descriptive modeling language, and solving algorithms, itsupports the entire model development process.
The OPL modeling language and the IDE enable you to develop, debug, test, and tune optimizationmodels.
CPLEX Optimizers offer C, C++, Java™, .NET, and Python libraries that solve mathematical programming (MP)problems. CPLEX also includes a MATLAB connector.
DOcplex, a Python modeling layer for both CPLEX and CP Optimizers.
Data and run management: Model/data separation allows a model to switch between data sourcesfacilitating migration through test and deployment phases.
Conflict detection/display and recommended conflict resolution: Detect and display conflictingconstraints in infeasible models using the CPLEX or CPOptimizer conflict refiner.
Relax constraints based on user defined priorities.
Execution tracing and profiling in the IDE: Full access to CPLEX and CP Optimizer log files allows tracking of the solve progress. Use the profiler tounderstand use of memory and time by different phases of the execution process.
Automatic performance tuning: Use the CPLEX tuning toolto automatically tune mathematical programming model performance.
Application Programming Interfaces: Access the CPLEXSimplex, Barrier, MIP and CP Optimizers through the CPLEXStudio IDE, through the Concert Technology API in C++, Java,or Microsoft .NET. Additionally, access the CPLEX Simplex, Barrier and MIP Optimizers through the CPLEX Callable Library, Python and MATLAB.
Operating systems supported: AIX®, Linux, macOS, and Windows.
Step 1: Access your software
If you download your product from IBMPassport Advantage®, follow the directions onthis page:
When CPLEX Optimization Studio is installed on MicrosoftWindows platforms, the Microsoft Visual C++ 2015 Redistributable Package (x64) must also beinstalled. This package installs runtime components of Visual C++ Libraries required to runapplications developed with Visual C++ 2015 on a computer that does not have Visual C++ 2015installed. If the installer detects that this package is not already installed, it explains what youneed to do to download it manually.
The installer contains a README.html file with information on how to get started using theproduct.
Step 2: Evaluate your hardware and system configuration
To find details of the hardware and software configurations required for the installation of IBMILOGCPLEX Optimization Studio, you can access the detailedsystem requirements from the product page:
Step 3: Access the documentation
A local copy of the product documentation is available after the product has been installed.
An online version of the product documentation is available at:
Step 4: Install the product on your system
To install the product follow the detailed step-by-step instructions provided in the installerspecific to the platform on which you are installing IBMILOGCPLEX Optimization Studio.
Cplex 12.8 Download
The AIX and Linuxinstallers are executable files and, to launch an installation, the file should have executepermission and should be executed from the command line. For example, issue the command./<installname>.bin, where <installname> is the nameof the installer. You can give a file execute permission with the command chmod u+x<installname>.bin.
On macOS, CPLEX Optimization Studio requires Java SE Development Kit 8 for Mac OS X.

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: 12.10
Problem types supported: Linear and quadratic optimization in continuous and integer variables. Support is provided for both convex and nonconvex quadratic objectives, and for convex quadratic constraints.
Special forms detected: Logical implications in the form of “indicator” constraints. Convex quadratic expressions in objectives, and convex quadratic constraints of elliptic and conic types.
Algorithms available: For continuous problems, primal and dual simplex, interior-point (barrier); for integer problems, advanced branch-and-bound with presolve, feasibility heuristics, and cut generators. For continuous problems comprised mostly or entirely of linear network flow constraints, network simplex.
Special features: Shared-memory parallel processing for barrier, branch-and-bound. Concurrent optimization by several methods to determine best choice. Special facilities for parameter tuning and infeasibility diagnosis.
