_gso.slk file
The _gso.slk file is a Microsoft SLK Data Import format results file.
File Creation
This file is created when Global Search Option (GSO) is activated and executed using the DGLOBAL I/O Option and the DGLOBAL Bulk Data Entry, respectively. This file outputs the results of Global Search Option (GSO).
File Contents
| Result | Description |
|---|---|
| Optimized Designs | It contains the list of unique and similar optimized designs based on the Global Search Option (GSO) method. The designs in this resulting subset of the total design space are then sorted based on their rank (based on the number of convergences from unique starting points to result in a specific design). |
File Format
The file uses the following format for the designs optimized from specified starting points.
Unique Designs
| Design Rank | Starting Point | Times Found | Directory Name | Objective Function | Constraint Violation | Max. Obj. Deviation | Avg. Obj. Deviation | Max. DV Deviation | Avg. DV Deviation | DV1 | DVN |
All Designs
| Design Rank | Starting Point | Unique Design | Directory Name | Objective Function | Constraint Violation | DV1 | DVN |
Where,
- Data
- Description
- Design Rank
- Denotes the rank of the design. This is assigned based initially on the values of Constraint Violation and then the Objective Function values.
- Starting Point
- Denotes the starting point of the optimization for a design in the design space.
- Times Found
- The number of times designs (from unique starting points) converge to the same design.
- Directory Name
- Name of the Directory where the output files associated with the specified design are stored.
- Objective Function
- The value of the Objective Function for the current design.
- Constraint Violation
- The value of the Constraint Violation for the current design.
- Maximum Objective Deviation
- The maximum deviation (of a design) from the objective function among designs from unique starting points that converged to this unique design.
- Average Objective Deviation
- The average deviation (of a design) from the objective function among designs from unique starting points that converged to this unique design.
- Maximum DV Deviation
- The maximum deviation between two design variables in the design space among designs from unique starting points that converged to this unique design.
- Average DV Deviation
- The average deviation between design variables in the design space among designs from unique starting points that converged to this unique design.
- DV#
- The various design variables values represented by DV1, DV2,....., DVN.
- Unique Design
- Represents the Design Rank used in the Unique Design table.
