comment 1-D heat diffusion in a bar with fixed temperatures at the edges
A closed-form solution $u(x,t)$ is what I'm looking for, if it exists.

comment Find the nearest point that lies within a polygon specified by 6 linear inequalities
If I'm finding all the intersection points anyway, I might as well just collect the segments and use a point-segment distance test and take the minimum. I was hoping for something a little more elegant :/

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).

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.
