# Statistics Parameter Panel

Statistical options are:

- Convergence rate threshold. Provided the target value is zero, convergence is assumed if a value smaller than this threshold is reached. For multi-run experiments, the number of hits is counted using this criterion.
- Number of multi-runs. To achieve statistically meaningful results on how well a certain optimizer works on a given problem, set this number to do several runs in a row. The plot will be averaged, while all data can be collected in an output file or text window.
- The fitness to plot. Define which fitness values to plot to the graph window after every generation. Select "best", "worst" or both.
- Result file name. If you want to collect optimization data, set this String to a desired file name. Optimization results will be written to the indicated file in the working directory.
- Show text output. If activated, the optimization data will also be shown in a graphical text window for immediate viewing.
