PSG Parameter in General (Text) Format
Contents
PSG Parameter in General (Text) Format is a string that specifies parameters value.
Syntax
parameter_<parameter_name>
Description
Parameter is defined in a file containing Problem Statement as a text before text of Problem Statement in General (Text) format. Using row with parameters description inside body of Problem Statement or after produces an error.
Parameter is defined by equality:
parameter_<parameter_name> = string
Parameter may have only one value at once.
Parameters can be specified in one line of Problem Statement with separator ";" , or in different lines.
Remarks
| • | Name of parameter parameter_name should not exceeds 128 symbols, it is not case sensitive, and includes only alphabetic characters, numbers, and underscore sign, "_". |
| • | Value of parameter string is a text 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 Parameters in the Problem Statement:
parameter_a = -0.00078672; parameter_b = 0.00064483
parameter_c = vector_cl, matrix_y; parameter_d = poinT_problem_11;
maximize

linear(matrix_y2)
MultiConstraint: >= vector_lb
