About CPLEX files

I would like to ask a few primitive questions about CPLEX:

There is a model, which is formerly written by someone else. Also, the .mod file is connected with a .dat file. Do I need to create a special OPL project area to use these files?

Do I need to open the .dat file with it?

Do I need to create and run a special configuration for it?

What are .ops or setting file used for? Why is it not involved in many projects?

I open and run these files directly (without opening the relevant .dat file and also without running configuration) from the file section and the result is obtained. Does it mean that I just need to open .dat and create a configuration while creating a new model myself?

Solution

  • I you want to run within the IDE you need some run configuration. You may also use the command line oplrun.

    See

    project OPL example

    .ops files are settings. They're optional
