How do we find an objective function given an optimal solution ??
@itsdannyftw
8 жыл бұрын
So do alternative optimal solutions always exist when the slope of the objective function equals the slope of any of the constraint boundary line slopes, in both a max or min LP problem?
@joshemman
8 жыл бұрын
+itsdannyftw Alternative optimal solutions exist only if the constraint (whose slope equals the objective) is BINDING. If that constraint is redundant, for example, it won't even be part of the feasible region.
@itsdannyftw

Joshua Emmanuel Thank you for clarifying Josh. Is the intuition behind this simply because the isoprofit (or level curve or objective function line) normally crosses/intersects/touches the last corner/extreme point, and given that boundary line associated with this corner point has the same slope as the isoprofit line, then in that case, the isoprofit line would not cross a single point, but an entire 'edge' of the boundary line? (because it has the same slope and thus are parallel, hence all the points on that 'edge' would be feasible solutions and result in the same objective function value). Therefore, if a boundary line is not associated with the feasible region, and thus has no effect on the feasible region (that is, it's a non-binding constraint), then that would mean the isoprofit line (used to determine the optimal solution) would never cross/intersect/touch this boundary line...hence no alternative optimal solutions would exist or... I think similarly, put another way, even if they did intersect, it wouldn't be an optimal solution, hence, same result, no alternative optimal solutions would exist. Are there any flaws in this entire rationale? Or would my understanding be OK?

You're right. The slope in the objective function is -1/3. The factored value should be 2, not 1/2.
