I was hoping for something a little more elegant :/ Apr27 comment Find the nearest point that lies within a polygon specified by 6 linear inequalities I'd rather avoid finding all the intersection points, since I'm not really sure how to deal with points that are outside the valid region (e.g. the points where the green line intersects the two blue lines on the left). Apr27 comment Find the nearest point that lies within a polygon specified by 6 linear inequalities I'm not too familiar with Lagrange multipliers, but from what I can see the technique is useful for minimising within equality conditions, not inequality conditions.
