Hacker News with Generative AI: Game Theory

Beating the Crowd (withentropy.com)
Suppose you are participating in an auction for a box. Nobody knows exactly what is in the box, but they are bidding on it for various reasons; some think they can make money, some might have sentimental reasons, and others might just be having fun. You yourself are trying to make money. You asked around a bit, did some research, and think that you have a good estimate for the value of the box.

Arbitrage and equilibrium in the Team Fortress 2 economy (2012) (archive.org)
Arbitrage is the holy grail of every trader. The dream of buying low and selling high (for this is what arbitrage is all about) is the driver of all commerce but also its own worst enemy: for as everyone is trying to pursue it, the potential for arbitrage disappears. And when it does disappear totally, we have equilibrium (the holy grail of the economists).

Learning about Innovation from Half a Century of Conway's Game of Life (stephenwolfram.com)
Things are invented. Things are discovered. And somehow there’s an arc of progress that’s formed. But are there what amount to “laws of innovation” that govern that arc of progress?

Breaking Bell's Inequality with Monte Carlo Simulations in Python (bytepawn.com)
In this article, we explore a game that challenges the very foundations of classical physics and introduces us to the strange world of quantum mechanics. The game involves three players — Alice, Bob, and Victor — who perform a series of experiments to test a fundamental principle known as Bell's theorem. By carefully selecting their measurement devices and analyzing the outcomes, Alice and Bob aim to determine whether the physical world can be explained by deterministic local hidden variables.

Analysis of adversarial binary search game (wordpress.com)
Alice and Bob are at it again, this time playing a game called Binary Search. Alice begins by secretly selecting an integer *key* from 1 to , then Bob makes a series of integer guesses, to each of which Alice responds indicating whether the guess is correct, or higher than her selected key value, or lower. Bob must pay Alice one dollar for each guess (including the final correct guess). How much should Alice be willing to pay to play this game with Bob?
