    A human who is not me, a carrot, a potato, and I need to cross a river. There is a boat that can only carry 3 things across the river. I cannot be left alone because if I am, I will run away. How does the human get us across the river

    The response:

    Here’s how the human can get everyone across the river:

    Trips:

    Trip 1: The human takes the carrot and the potato across the river. Trip 2: The human returns alone. Trip 3: The human takes you across the river. Trip 4: The human returns with the carrot. Trip 5: The human takes the potato across the river. Trip 6: The human returns alone. Trip 7: The human takes the carrot and you across the river.

    Explanation:

    This solution ensures that you are never left alone on either side of the river. The human acts as the ferry, carefully transporting the items and you while always being present to prevent your escape.













  • “Conspiracy” is a colorful way of describing what might boil down to Gagniuc and two publicists, or something like that, since one person can hop across multiple IP addresses, etc. But, I mean, a pitifully tiny conspiracy still counts (and is, IMO, even funnier).

    A comment by Wikipedia editor David Eppstein, theoretical computer science prof at UC Irvine:

    Despite Malparti warning that “it would be a waste of time for everyone” I took a look at the book myself. 60 pages of badly-worded boring worked examples with no theory before we even get to the possibility of having more than two states. As Malparti said, there is no theory, or rather theory is alluded to in vague and inaccurate form without any justification. For instance the steady state (still of a two-state chain) is first mentioned on 46 as “the unique solution” to an equilibrium equation, and is stated to be “eventually achieved”, with no discussion of exceptional cases where the solution is not unique or not reached in the limit, and no discussion of the fact that it is never actually achieved, only found in the limit. Do not use for anything. I should have taken the fact that I could not find a review even on MR and zbl as a warning.

    It’s been a while since I’ve seen a math book review that said “Do not use for anything.”

    “This book is not a place of honor…”
