  • 1.  About the Lagrangian Relaxation example

    Hi, All.

    I try to run the LR example : Lagrangian relaxation for a location-transportation problem.

    However, there are two errors in the problem report:

     

    Description Resource Path Location Type
    IBM ILOG CPLEX µÄÒì³££ºCPLEX Error  1016: Restricted version.  Problem size limits exceeded¡£ LagrangianRelaxation.mod /LagrangianRelaxation 59:0 C:\Users\Hello\Application Data\IBM\ILOG\CPLEX_Studio125\workspace\LagrangianRelaxation\LagrangianRelaxation.mod OPL Problem Marker
    IBM ILOG CPLEX µÄÒì³££ºCPLEX status = 1016¡£ LagrangianRelaxation.mod /LagrangianRelaxation 59:0 C:\Users\Hello\Application Data\IBM\ILOG\CPLEX_Studio125\workspace\LagrangianRelaxation\LagrangianRelaxation.mod OPL Problem Marker
     

    Meanwhile, the following is the content of Scripting log:

     

    --- LP Relaxation ---
    // Script execution failed with status -2.

     

    This is my first to import example, is there any people know the reason ?

    Thank you!

    I think the error message is pretty clear: you have a license that limits the size of the problems that can be solved (are you using a trial or eval version?) and the LR example exceeds this limit.

    In order to solve the example you will need a full license. Note that there are free licenses for academic use. You just need to apply for academic initiative program.
