An 80% good enough solution would be to have it periodically say "Hey, you. You're finally awake."

Do they all live at the same address of the overseas freight forwarder too? I've sold stuff on eBay to someone in Europe who had me ship to the same address in Delaware. I was confused so I googled the address and turned up the freight forwarding service.

reminds me of that Hunter S. Thompson quote from Fear and Loathing in Las Vegas, "Not that we needed all that for the trip, but once you get locked into a serious [solar power setup], the tendency is to push it as far as you can.”"

I always felt that part of the interview process is the candidate asking clarifying questions as well as making and stating assumptions.

The Probabilistic Bisection Algorithm by Horstein, original paper is "Sequential transmission using noiseless feedback," IEEE Trans. Inform. Theory, 9(3):136–143. https://ieeexplore.ieee.org/document/1057832

Here's a nice presentation on an analysis of the method, references start on slide 47

https://people.orie.cornell.edu/pfrazier/Presentations/2014....

Paraphrasing the theorem from Jedynak, Frazier, Sznitman (2011):

Suppose [flake probability] is constant, known, and bounded away from 1/2, and we use the entropy loss function. ... The policy that chooses [next test point] at the median of [current posterior distribution] is optimal.

And some python code that implements a version of the analysis
