    Hello,

     

    I am trying to solve a mixed integer problem to which I know there are more than one optimal solution. But I can't find all the optimal solution in OPL. Is there any way to find out the alternate optimal solutions in OPL.

    I tried below code, but it isn't working-

     

    execute
         {
        
         cplex.solnpoolagap=1; 
         cplex.populatelim=200000000; 
         cplex.solnpoolintensity=4;

              
         }

     

    Any help will be appreciated. Thanks in advance.

    Hi,

    you should have a look at the example

    solpoolscript.mod

    in

    CPLEX_Studio127\opl\examples\opl\warehouse

    regards
