This is really cool and after reading the article, I'm left with the desire to ask a bit more. A game like 2048 is pretty straight forward and after you figure it out (i.e. you understand the 4 pieces of advice the AI figured out) the game feels like mostly chance (as the article states). >Some games ended in a few minutes due to a series of unfortunate random tile spawns, while others nearly lasted 4 hours and reached scores previously thought impossible. So is the AI's strength in this instance that it's relentless and doesn't get tired? Or does it have a few other insights on the game that most humans miss? Are there other comparisons of other AI's and where their advantage comes from? (strategy vs. endurance) Or is the AI's outcome distribution very similar to a sampling of human outcomes?
