If it's any consolation, you are almost certainly within ~3 years of understanding the solution and a dozen variants. It's not a super deep area. Probably doesn't really require calculus (you need continuous as in 'the lion doesn't teleport; that's cheating', but I think not much more).

Not FOSS, but ad free and its been able to find the hidden RSS feeds for things OK. FeedDemon at: http://bradsoft.com/

Probably not what you are after, but maybe someone with a similar question.

Didn't realize it could do more than 2! That's wonderful!

May I ask the artist/source? Is this something I should know?

Ah, so it's the probability you win by playing randomly. Gotcha. That makes sense, it becomes a choice between 2 doors

Why do you have a P(x1) = 1/2 at the start? I'm not sure what x1 means if we don't specify a strategy.

Agree that this is a circuit you should never use. But theoretically it could be a circuit that does.. something? Maybe?

Would the tears and their paths make interesting circuits? Salt water is probably a reasonable conductor, but I'm not sure how to model the eyes.

It depends on what the app is for I think. For apps that just need to work (I can't afford it to break at a bad time), the most important thing is that it's well tested (lots of downloads) and has few 1 star reviews. I'd probably thus require 1M+ downloads (or perhaps 100k), and then rank those by % of downloads that result in 1 star reviews. That is: take the number of reviews, multiply by % 1 star, and divide that by number of downloads. (I assume that if someone has a 'necessary' app break, they will leave a review. This might be false if someone is using bots to inflate download numbers)

I should have mentioned; the blog linked was new to me. Other posts include testimonials from mathematicians, which I found helpful to read.

Ah. I see. For this, someone will need to dive into what 'after optimizations' means I think. I don't think the 6 examples are enough to read it off, a quick search on OEIS for the 3 cards per suit cases finds nothing.

I meant the video linked in the review, I think it's hosted on Scott's account, either because this is his report or because he's hosting it for anonymity.
