Optimization Tool Output

To view the Optimization Tool output, click on the View Output button. The Optimization Tool Output can be viewed at any time, and can be updated during the optimization run using the Refresh button. The Optimization Tool Output Dialog has six tabs, each displaying different information about the optimization run. Each page can be copied as an image and, if applicable, as text using the Copy button.

Problem Definition

This tab contains a summary of:

  • Objectives
    • Function
    • Weight
    • Goal
  • Constraints
    • Function
    • Upper Bound
    • Lower Bound
  • Design Variables
    • Name
    • Start Value
    • Upper bound (continuous design variables)
    • Lower bound (continuous design variables)
    • Selected alphabet (discrete design variables)
  • Algorithm
    • Name
    • Options

Best Design(s)

If the problem formulation is single-objective, the Best Design tab is displayed, showing the last design improvement reported by the algorithm.

If the problem formulation is multi-objective, then Best Designs Tab is displayed, showing the Pareto front of best designs. The different best designs in the Pareto front can be selected using the Select Design drop-down box. All of the designs in the Pareto front can be show in a table form by clicking the Show in Data Explorer button.

Convergence/Pareto Chart

If the problem is formulation is single-objective, the Convergence Chart tab will be displayed.

If the problem formulation is multi-objective, the Pareto Chart tab will be displayed.

Results

The Results tab displays a report generated by the algorithm summarizing the results of the optimization run. This can either be in HTML or plain text format depending on how the algorithm is written.

Details

The Details tab displays a report generated by the algorithm detailing the operations performed by the algorithm during the optimization run. This can either be in HTML or plain text format depending on how the algorithm is written.

Once the Details report is above 1 megabytes of data the report will instead be split to show the first 512 kilobytes and the last 512 kilobytes. The location of the file containing the full contents is shown at the bottom of the Details report.

Messages

The Messages tab displays all of the messages that the algorithm sent back to the infrastructure. These are the same messages that get displayed in the Status area on the Optimization Tool form. These messages can be filtered by message type:

  • – Info: Informational messages that indicate that the algorithm is operating as expected
  • – Warn: Warning messages that indicate that something happened that might affect the results, but did not prevent the algorithm from continuing
  • – Error: Error messages that indicate that an error occurred that prevented the algorithm from continuing
  • – Debug: Debug messages that help in tracking down the causes of errors
