The USAMO winner list is here:

Apparently the final team was not chosen strictly from the top 12 (Michael Kural and Ashwin Sah were Honorable Mentions).

New comment by HardyLeung in "Lee Sedol Beats AlphaGo in Game 4"

HardyLeung — Sun, 13 Mar 2016 08:55:30 +0000

Lee Sedol winning, and keeping his cool and not make any mistakes. AlphaGo, on the other hand, went bonker especially towards the end but it got into bad territory not because of silly mistakes but brilliant play by Lee Sedol.

Could it possibly be that both of the mistakes were bugs? Perhaps it suggested a non-sensical position such as (25.23, 13.15), and it was snapped to (19, 13) :D

New comment by HardyLeung in "SVGnest: Efficient packing of irregular shapes with JavaScript"

HardyLeung — Sat, 16 Jan 2016 04:10:32 +0000

This is interesting. I wrote Tagxedo http://www.tagxedo.com which is another kind of constrained packing problem and there is a bit of similarity in the approaches. This is the first time I've heard of CNC packing and part nesting... May I ask what kind of software and how much they are selling for?

New comment by HardyLeung in "Generating Word Search Puzzles"

HardyLeung — Sat, 26 Sep 2015 16:49:46 +0000

Nice. One improvement would be to throw in letters in frequencies proportional to the likelihood of appearance in actual text. For example:

http://www.math.cornell.edu/~mec/2003-2004/cryptography/subs...

Though this is a simple problem, if you are picky there are actually other considerations... how well do the words intersect (do you prefer more of a sparse tree-like structure, or maximal mesh-like intersection). What is the optimal dimension of a puzzle given the input. How the order of words (random vs. longest word first) affect the quality of the puzzle. etc. I have a half-done word search puzzle app (with a twist) so this piques my interest.

But I like this one nice and clean.

I tried out the zooming capability (nice) but it seems like your stroke width does not change in response to the zoom level (at least not in lock step)? So the redness in the lady's dress changes as you zoom. Isn't that a problem?

It is a balance between playability and automation. Even minesweeper does that (auto deduce that a large region can be opened up). What I described is only the first-order "convenience" checking to avoid the pain of going way back because of a miscounting.

Regarding the hint button. I don't want to use it precisely because I don't want to "win" by repeatedly getting hints.

Another feature request... if a tile is already illegal (too many committed blue in line of sight, or no way to commit more blue to satisfy requirement), flag it already. I think the biggest pain is the counting. Otherwise, a nice game!

I see that this is very similar to Paper by 53 in several aspects... Is that what you are trying to compete with? In that case, I wonder the logic of an upfront price instead of Paper's strategy which is to give you something to try out... At $4.99 a pop, it is much harder for someone to take the plunge.

Yes, linear gradient within each triangle. It has a non-gradient mode but not turned on. The difference is minor though: Gradient = more "silky" and less triangular. No gradient = a bit more flat.

Neat. I have a related project called Polygonian -- http://www.polygonian.com -- runs on browser and requires Chrome Native Client that does something similar. Here's the output of a Lincoln portrait using similar point count:
