Hi,

I am using OPL 6.3 with cplex 12.1.

I have written a model in OPL. My data is coming from MS Access. I use the .dat file to import and export data between Access and the model.

What I would like to do is to be able to export a problem status (or cplex status, or optimizer status) to the Access. Basically what I want to know is whether the model is optimized (including true optimized, or tolerance) or not. I do not know what syntax or code I need to use to get this. I tried to use "cplex.getcplexstatus", but not quite understand how meaning is. Sometimes I get the value of 102??

I expect to see something like Yes or No. No would mean infeasible, unbounded,... problems.

thank you for your help!

The method provides a solution status code. You can look up the possible status codes in the CPLEX reference manual. For example, CPXMIP_OPTIMAL_TOL = 102 means that the solution is optimal inside tolerances (i.e., optimal up to the specified MIP gap, which is 0.01% by default).

Hi,

thanks for your reply.

I put the code at the end of my model like this....

execute{

writeln(cplex.getCplexStatus());
};

When the problem is feasible, it works fine. But when the problem is infeasible, there was no scripting output at all.

I have also read the documentation and found out that when I run the model by using OPLRUN in the command prompt, the OPLRun will ourput a "solved" status if it is solved. how can I get to this status in OPL?

thanks,
Boon
