Feasibility Indicator

ODOP has a multi-colored Feasibility Status Indicator that provides feedback on the viability of the current design relative to constraints and FIXes. The indicator provides at-a-glance interpretation of the Objective Value.

Graphic	Description	Obj Value
	STRICTLY FEASIBLE	zero
	FEASIBLE	< OBJMIN
	CLOSE TO FEASIBLE	< 4x OBJMIN
	NOT FEASIBLE	> 4x OBJMIN

The tool tip on the label "Status" provides the numeric values of the current Objective Value and OBJMIN:

Use the Search feature (Action : Search menu) to obtain the lowest Objective Value consistent with the FIXes and constraints imposed on the problem. Because Search stops if the Objective Value falls below OBJMIN, results in the green zone are considered "as good as feasible" or simply just "FEASIBLE".

The value of OBJMIN may be adjusted on the File : Preferences menu. Also, OBJMIN is one of the values set by the increasePrecision script that is reached from the Action : Execute menu.
