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 an at-a-glance interpretation of the Objective Value.

Graphic	Description	Obj Value
	STRICTLY FEASIBLE	zero
	FEASIBLE	< OBJMIN
	CLOSE TO FEASIBLE	< 8x OBJMIN
	NOT FEASIBLE	> 8x OBJMIN
	FEASIBILITY UNDEFINED	Infinity

The tool tip on the blue triangle indicator provides the numeric values of the current Objective Value:

The tool tip on the info icon to the right of the "Search" button provides the numeric value of OBJMIN in addition to the current Objective Value:

Use the Search (solve) feature (Search (solve) button or Action : Search (solve) menu) to find a solution. Specifically, to obtain the lowest Objective Value possible 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 available from the Action : Execute menu.
