it's certainly a space-filling curve problem, but it's not the traveling salesman problem. you aren't just trying to avoid revisiting nodes -- you're trying to maximize the *angle* between edges when you visit the node, to avoid overlap while you're turning the mower. which is at least an interesting wrinkle in the problem.

insightful, really?

you certainly can call someone a "fatass". there is no law against it. you can call someone anything you want, but in return someone might call you an "asshole", and they might be right.

is there a line between political correctness and politeness? or do you think we need to get rid of that too?
