PSG Parameter in general format is an object specified by:

 

 

Name

Name of a PSG Parameter is a string (used in problem statements). Name:

 

Value of Parameter

Value of parameter  is a strings containing any permitted in Problem Statement substrings i.e. replacing parameters in initial Problem Statement by its values should give a correct resulting Problem statement. Beginning and end of separate string are defined by nonblank symbol. So a black symbol is permitted inside strings.

 

 Example

PSG Parameter should be defined in appropriate format in different PSG Environments:

 

Run File Environment

 

PSG Parameter in General (Text) Format of PSG is defined in the Problem Statement as the string before main body of problem:

 

parameter_alpha = 0.95;

 

minimize

 cvar_risk(parameter_alpha,matrix_cut)

Value:

 cvar_risk(parameter_alpha,matrix_take)

Box: >= -10, upperbounds = 10, <= 10

MATLAB Environment

 

PSG Parameter in MATLAB Environment is an element of the structure:

 

>> toolboxstruc_arr =

     type: 'parameter'

     data: [1x1 struct]

   string: [1x1 struct]

 

>> toolboxstruc_arr.data

ans =

   name: 'alpha'

   data: 0.95

 

>> toolboxstruc_arr.string

ans =

   name: 'alpha'

   data: 'parameter_alpha_data'
