_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,

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	This represents the Design Rank used in the UNIQUE DESIGN Table.
