Options tab (Optimized Run only)
The Options tab is where you define the parameters for the genetic algorithm. Options relate to optimized design runs only and therefore are not available for manual design runs. Use these settings to fine-tune the way the GA finds results. If adjusting a particular GA control gives you better results, pursue the approach to maximize your design.
| Stopping Criteria | Max. Trials - Set the maximum number of calibration trials you want the GA to process before stopping. Non-Improvement Generations - Set the number of maximum number of non-improvement generations you want the GA to process without calculating an improved fitness. If the GA makes this number of calculations without finding an improvement that is better than the defined Fitness Tolerance, the GA will stop. Non-Improvement Generations works in conjunction with Fitness Tolerance. |
| Top Solutions | Solutions to Keep - Select the number of solutions you want to keep. For a design type of Minimize Cost or Maximize Benefit, Darwin Designer retains the top feasible solutions according to the value of the objective function. If the user-specified number of top solutions is greater than the number of feasible solutions found, Darwin Designer reports all the feasible solutions found. |
