Hello Michelle,
There is some guidance in the Darwin Designer Help documentation, such as in the section "Advanced Darwin Designer Tips". Overall, you can start with the default values for the the parameters in the Options tab and make adjustments to try to find other solutions. What you would use will vary depending on the model, but the Help topic above has some general ranges for the different parameters. If you ever want to return to the default values, you simply need to click the Reset button.
For the second item, the notification mentioned means that Darwin Designer stopped its calculations because the value for "Non-Improvement Generations" was reached. You can try other values for the parameters in the Options tab or use the results that were generated from this particular Darwin Designer run.
If that doesn't help, or answer your question, please clarify the issue and provide some additional details. Thank you.
Regards,
Scott
