Could you please be more specific? What options are you talking about? What API do you use?

I don't use any API at all.Just a question about TSP, I want to konw how cplex set the parameters about the TSP model.When I see  the help document ,it introduce more options than the file of .ops.

This question would best be raised on the OPL Forum.

But in general I think that it may well be that not all existing parameters are visible in the OPS editor. I looked at the OPL examples directory but cannot find an example that is called TSP. Could be more specific about which example you are talking and which help document you are referring to?

It's very nice of you to answer my question.

The example of TSP is writed by meself, a very simple model.The help doucument is the IBM ILOG CPLEX Optimization Studio.I am looking at the Parameters of CPLEX, and I find that it has more options than the OPS editor.Could you please explain how the cplex set parameters about the example of gas for me.Thank you very much.

Like I said, there are parameters that are not directly editable via the OPS editor (see also here).

But all parameters can be changed via scripting statements like this (see also here)
execute { cplex.params[N] = value; }
where N is the number of the parameter. A list of all parameters (including their numerical values) can be found here.
