Markov random fields area popular model for high-dimensional probability distributions. Over the years, many mathematical, statistical and algorithmic problems on them have been studied. Until recently, the only known algorithms for provably learning them relied on exhaustive search, correlation decay or various incoherence assumptions. Bresler [4] gave an(More)
Braid is a 2008 puzzle game centered around the ability to reverse time. We show that Braid can simulate an arbitrary computation. Our construction makes no use of Braid’s unique time mechanics, and therefore may apply to many other video games. We also show that a plausible “bounded” variant of Braid lies within 2-EXPSPACE. Our proof relies on a technical(More)
