Does CPLEX 12.9 have limit in the number of variables or constraints?

  • 1.  Does CPLEX 12.9 have limit in the number of variables or constraints?

    Posted Mon February 13, 2023 10:02 AM

    Hi,

    Does the product "<bx-table-cell _ngcontent-aur-c13="" class="dswdown-big-column" role="cell"><slot>IBM ILOG CPLEX Optimization Studio 12.9 for Linux x86-64 Multilingual</slot></bx-table-cell>" with the part number "<bx-table-cell _ngcontent-aur-c13="" role="cell">CNZM2ML</bx-table-cell>" have a limit in the number of variables or constraints for a model? 

    I downloaded it from the no-cost academic version and did not have a subscription. It works but I have no idea if there is a limit in variables or constriants.

    Thank you!

    Best regards,

    Dear Xuan,

    It actually depends on the amount of memory available on your machine.

    This discussion might help you get an idea:

    I hope this helps.

    Dear Renaud, please check the following,

    I am currently working on a research project that involves implementing branch and price. I would like to know if it is possible to access Cplex(Academic Initiative version) from Visual Studio using C# without the limitation of the number of variables (1000).
