hi all,

when i run my cplex model,"CPLEX Error  1016: Restricted version.  Problem size limits exceeded." occurs,what is the problem. I have searched in

internet,some said it is because my cplex is a trial version,is this right? and another question,i want to round  a data which data type is IloNumVar or

IloNumExpr,is there any method like Math.round() in cplex. Thanks a lot in advance.

Please create two different posts if you are asking two questions that are completely unrelated.

1. Yes, the error message 1016 means that you are using a trial/restricted version. These versions are limited in the number of variables/constraints they can process.
2. There is round() function that you could apply to an instance of IloNumVar. If you intend to round the value of that variable in a solution then use Math.round(cplex.getValue(v)). If you instead want to have something round(x)+y<=5 as a constraint then there is no easy way to do that. You would have to use additional integer variables to model that.
