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
StrictlyFeasible STRICTLY FEASIBLE zero
Feasible FEASIBLE < OBJMIN
Close To Feasible CLOSE TO FEASIBLE < 4x OBJMIN
Not Feasible NOT FEASIBLE > 4x OBJMIN
     

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

Tool Tip

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.
