Initializing help system before first use

# Tuner Settings

In the Run Model dialog box, you can configure the following settings that affect the tuner's behavior:

- Session Name: A name for the tuning session. It will determine the directory where tuner result files are written. The name will also appear in the tuner table. If you plan to combine the data from several tuner sessions, the name can serve to differentiate the results from different sessions.
- Method File: A path to a tuner method file. A tuner method consists of a list of controls for the tuner to try with. You can create a template tuner method file by opening the File menu, clicking New and choosing Tuner Method.
- Tuner Time Limit: The maximum time in seconds to spend tuning the model. If set to zero, no time limit will be imposed.
- Permutations: The number of times that the problem will be randomly permuted and solved while tuning it. This can improve stability by avoiding lucky controls that show improved performance by coincidence rather than structural reasons. See section Tuner with Problem Permutations in the Xpress Optimizer Reference Manual.
- Tuner Threads: The number of different control settings that will be run simultaneously.
