Cutting a rectangle into an odd number of congruent pieces
Exhaustive search for non-rectangular n-ominoes n<=13 turned up no k-tile rectangles for k in [5,7,9]. Before I continue onward and upward, I should probably cull poor candidates before starting the Dancing Links routine. I'm already eliminating tiles with the wrong checkerboard parity (abs(white-black)>1), but are there any other quick tests I should be doing? NOTE: this posted prematurely...there are still a few 13-ominos left... |

Optimal strategy for game of 'online sorting' into a poset
I hope I didn't seem dismissive, just had no better idea how to approach the question for chains than for the general case. I am appalled at my own ignorance regarding dynamic programming, but hope to make progress towards remedying that this weekend. FWIW, all purely continuous distribution functions yield equivalent strategies when the constraints are ordinal. |

I have some good approximations, but as I try to refine them I get the impression that I'm trying to mow the lawn with a million nail clippers...figured I should bring in some fresh eyes. |

Thanks! No, but I know one where the poset is an antichain. ^_^ |

Is there an observer dependent mathematics?
I have to wonder whether it's entirely safe to refer to Greg Egan's "Luminous" ^_^ |

Reals with integer powers bounded away from integers?
Nifty...thanks! Somewhere between 7.3769347535 and 7.3769347577 lurks a number whose powers never stray within 1/3 of an integer... |
