Model is Square System

Type : Selection

Range : The settings listed below

Default : Off

If this option is turned on, the modeler declares that the model is a square system. This implies that:

• The number of non-fixed variables (including slack in inequalities) must be equal to the number of constraints,

• No bounds must be active in the final solution, and

• The basis selected from the non-fixed variables always must be nonsingular.

Possible values are:

• Off

• On
