### Re: 1190: "Time"

My latest ==CRAZY== idea: They are actually on a hovercraft! They drive(?) along the beach, so they have unlimited access to water and sand. They are heading to the river. When they disappear, it's just because one of them is steering. Waterlevel: I am guessing that as they accumulate more sand on ...

### Re: 1190: "Time"

Seems to have shifted another half-pixel, this time diagonally right and down.

### Re: 1190: "Time"

We might be in for an arbitrarily long stretch of panels with no one in them -- and so far, human activity has been the only cause of change. This might be the end.

Or maybe Megan will come back.

### Re: Asymmetric nontrivial 6-RPS

Proof sketch for impossibility in n<6: One move: degenerate case. Technically fulfills the requirements. Two moves: without loss of generality, let A>B. A strictly dominates B, contradicting nontriviality. Lemma: to satisfy nontriviality in n>1, it is a necessary condition that each move win against...

### Re: The Batman equation

Someone type up the equation in either latex pretty-ness or standard typed out form so it can be copied/verified. I think this should be right: \left( \left( \frac{x}{7} \right) ^2 \sqrt{ \frac{ ||x| -3 | }{ |x|-3 } } + \left( \frac{y}{3} \right) ^2 \sqrt{ \frac{ \left| y + \fra...

What‽

Well unless you can show me a counterexample, I'm going to go on believing they're equal...

Anything that's not a number, such as an ordered pair.

### Asymmetric nontrivial 6-RPS

(My brother did most of the heavy lifting on this problem.) I was interested in the class of games describable as rock-paper-scissors variants, such as rock-paper-scissors-lizard-spock. In particular, I wanted to know if it was possible to construct a game that had no symmetry to it. By symmetry I m...
