Equal Bounds Imply Nonvar

Type

Selection

Range

{ On, Off }

Default

Off

With this option you can specify how variables for which the lower bounds equals the upper bound end up in a generated mathematical program.

If the option is switched off, then such a variable will appear as a ‘frozen’ column in the generated mathematical program. If the option is switched on, then such a variable will not appear as a column in the generated mathematical program (similar as if the nonvar status is > 0).

Remark

If for a variable the lower bound equals the upper bound, and the nonvar status is not equal to 0, then the nonvar status is leading, and thus this option will be ignored.

So for example if the option is switched on, the bounds are equal, but the nonvar is -1, then the variable will appear as a frozen column in the generated mathematical program.
