Dear Toufik,

Send an email to IBM co. and mention that you want to use the CPLEX software for academic research. Then, you will receive an email from the closest IBM branch including a form to fill and sign it. Then, you will have an access to download the last version of the software. This is exactly what I have done for my research.

Regards,

You can download CPLEX from IBM website, e.g., https://www.ibm.com/products/ilog-cplex-optimization-studio (and select "Try free edition"). You should create an account and then you will have access to the download link. As far as I know, you can get a limited-problem size free version (with limits on the problem size, 1000 variables and 1000 constraints) and you can get an academic full free version by contacting IBM as mentionned by Mazyar.

Dear Toufik,

You can get access through the IBM Academic Initiative website (http://onthehub.com/ibm/). Just create an account (maybe you will be asked to provide some information about your affiliation and courses/projects related with use of CPLEX) and download CPLEX

Best regards,

José Luis

Thank you too much

which option from the attached picture should I select to download CPLEX for students?

Fatma, just search "CPLEX" in product search and you will find it. Note that you need to be signed into your account to download it.

Thanks to all. Was of great help.

can I use CPLX software without GAMS or AMPL programs

as I knew , CPLEX is just a "solver", or can be used as an optimization programming tool also ??

Yes, you can. CPLEX has APIs for MATLAB, Python and Java. IBM also has its own CPLEX Optimization Studio.

Dear Taoufik,

If u have an academic affiliation you can download the full version from IBM website

CPLEX seems not to be available from the Academic Initicative site:

https://ibm.onthehub.com/WebStore/ProductSearchOfferingList.aspx?srch=ilog%20cplex

For some reason the migration to Kivuto is not working and a search for CPLEX returns " No matching products are currently available". The best you can do is to contact directly IBM or Kivuto for support. I needed to re-instal my distribution and cannot find it anywhere. I did contact them, waiting for an answer.

Hi Diego

Did you succeed in downloading cplex ... all sites are returning error messages@

Dear Diego Ruiz-Hernández and Sameh Al-Shihabi

If problem still remains, try this link:

https://developer.ibm.com/docloud/blog/2019/03/12/cplex-optimization-studio-12-9-is-available/

After choose the Academic Initiative program.

Then you have to register or log in with your academic credentials.

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 :-)

Dear, Kiril Kuzmin. The "academic initiative" regester page shows "The services are down, please try again later ". Besides, do you konw the detailed install process description? Thanks in advance!

Dear Na Li

That's true, sometimes the services might be down, but it should not be for long time. I checked it today again -- it works, at least in Atlanta :)

Could you please, clarify what you mean when you ask about ``detailed installation process description''? Which system do you use? Windows/Linux? What are you planning to use CPLEX with (if any) -- MatLab, Pythin, etc...

Dear Kiril Kuzmin

Thanks for you reply. You are right, the server works well when I open it another day. I have installed CPLEX successfully. Thank you very much!

Hi guys,

I couldn't download Cplex from IBM website, it says that the server is down.

Could you please upload your installation file to Dropbox or Google Drive and share it with me?

Kiril Kuzmin,

I have registered the IBMid with an e-mail address and can use it to access other service of IBM website. but I failed to enter the following website for students or academics. They told me Does not match with invited Email@

https://my15.digitalexperience.ibm.com/b73a5759-c6a6-4033-ab6b-d9d4f9a6d65b/dxsites/151914d1-03d2-48fe-97d9-d21166848e65/technology/data-science  or https://ur-a2mt-prod.mybluemix.net/a2mt/email-auth

For I wish to get an academic version of CPLEX.

Thanks to all.

For me, I still cannot access the Academic initiative (AI) program. the attached message appears when entring my accademic email

Hello,

I think that it's working now through a new website. I uploaded IBM CPLEX 12.10 a few days ago. Please check the following link:

https://my15.digitalexperience.ibm.com/b73a5759-c6a6-4033-ab6b-d9d4f9a6d65b/dxsites/151914d1-03d2-48fe-97d9-d21166848e65/technology/data-science

All the best,

Walid

Walid Besbes Hello, would you please send me a Linux version of IBM CPLEX 12.10 or 12.9，I cannot reach the website you given and I also cannot reach academic version though I register an account using my college email. Thank you very much! My email is [email protected]

Hello Zongxiang, I am sorry for my delayed answer. I just see your message. Yes I can but the problem is that each time you will use cplex, the app asks your login&psw. Therefore you have to create an account.

PS: I checked the website when I saw your message, it is reachable my friend.

Hello everybody

Does ur academic version of IBM CPLEX studio have limitation of 1000 variables and 1000 constraint which means it does not work for big models ?

and pls inform me what is the solution ?

Ehsan Zangene, academic licence does NOT have such constraints!

Some time ago, however, I had a similar problem in Python: despite the fact that I had academic CPLEX installed, it gave me the error that I had exceeded the limit of 1,000 variables and 1,000 constraints. Reinstallation of Python cplex package helped.

Hi Kiril Kuzmin , I encountered same problem: exceeded limit of 1000 constraints in my version. Could you tell more details about "Reinstallation of Python cplex package helped" ? Thanks

The initial question of this thread seems to induce a neverending story ... As of March 2021, I recognize that IBM offers and pushes a new version of CPLEX Optimization Studio, 20.1, and took down all previous versions from the servers.

I work for the last two years with 12.8 academic, and wanted to update to 12.10 academic. My university is registered in the IBM academic initiative, so I could register myself as prof in the academic initiative with my universities e-Mail addy. So far so good. I followed the link path on the web site (ibm.com/academic ) down to a page on Data Science and there the tab "Software". There is a tile for ILOG CPLEX Optimization Studio and in it a link "download". Clicking this results in a message that the resource is currently unavailable .... I tried this on three subsequent days.

So I checked the free, but restricted "community edition". This is available for Windows, MacOS and Linux - but only in the new version 20.1 .

So as of today I assume that IBM has not prepared an academic version of V20.1 - but I hope they will do soon ...

(If anybody has an hint where I could find 12.10 academic, for Windows and MacOS, I would be happy. Due to Corona, my students have to install the software on their own computers, and so I have to deal with both Windows and MacOS - in our computer lab this wan't an issue, there we have only Windows computers...)

Please when I run a problem on CPLEX IBM I receive a long message box :

... 5 more

How can I fix that....
