    Hello, everybody,
    I'm now working on the topic of improving patient planning in the OR using linear programming. I have implemented my model in Cplex. 
    My objective is only the binary decision variable. Therefore, the question arises: Can I still call it Linear Programming? 
    many thanks in advance
    many greetings, Sherzod

    Hi,

    then it will be an IP model but CPLEX can solve that.

    You have an example of pure IP in CPLEX_Studio129\opl\examples\opl\lifegameip

    Hi Alex, 

    thank you very much for your quick reply. After your advice I have to change my model to linear programming in order to accept it as linear programming. am I right there?

     

    thank you in advance!!

    Regards,

    Hi

    do not change anything.

     

    By default OPL will use CPLEX MIP algorithms.

    If you write "using CP;"

    then CPO will be called
