    I have four now, and even go out of my way to use them a bit. My favorites from my collection are a little Dietzgen No 1773, which is surprisingly featureful for something that can…

    That is not accurate -- the Andromeda Galaxy is over 3 degrees wide. About 6 full moons.

    This seems like a cool concept, but it's broken for me. Firefox 113.0.2 shows the orbits and background, but no particles as far as I can tell. Chromium 120.0.6099.129 shows just a…

    There is a fixed probability of matching all numbers but the value of doing so varies, so sometimes the EV can be positive.

    This should be the page, but it requires a Flash plugin (so doesn't work for me): https://rifters.com/blindsight/vampires.htm

    In what appears to be the originating paper for UCT ("Bandit based Monte-Carlo Planning", L. Kocsis and C. Szepesvári, 2006), * The choice of action to be returned is the one "with…

    Excellent. I did want to eventually write something showing how to modify this algorithm to handle games with randomness, and ISMCTS at a glance looks like it does just that. Thank…

    I've updated the diagrams with a set of node values that (hopefully) make sense.

    Since the win counts are only incremented for nodes "moved into" by the winning player, UCB does correctly model the opponent's behavior here.

    I have to mark this one "cannot replicate". I see no sign of this behavior on my account.

    I found it impressive, and I've seen content here on HN that is less relevant than this.
