Show HN: TeXnique – A LaTeX Typesetting Game
One of the developers here! Right now, we compare answers visually, so for example `n \choose k` and `\binom{n}{k}` will both be accepted. However, sometimes there are things that look similar to the human eye, but are rendered slightly differently -- this is usually due to alignment, spacing, or size. For example, `\not\in` (bad) vs `\notin` (good) is a pretty annoying example. Making the comparison / feedback mechanism better is a tough problem. It isn't as simple as increasing the pixel threshold: replacing a + with a - has an extremely small pixel difference (and the two characters have the same width, so it doesn't affect anything else), but we shouldn't accept both.<p>Right now, the website is a super simple static HTML page. If we have time, we'd also like to add some new features, like a leaderboard and (hopefully) better comparison logic. Feel free to contribute, and we appreciate the feedback!
