    I'm kind of obsessed with this old puzzle. You need to move the piano to the lower LEFT corner by sliding the pieces.

    Curious if anyone has done any math things with such tile puzzles?

    It's easy to move it to the lower right, and possible but kind of hard to get it to the left.

    I guess what I want to know is "why is it so hard?"

    @futurebird that is a superb marketing gimmick, wow. I guess the issue is that you can't easily get the littlest blocks in the middle to get round to the far side of the big one

      @futurebird

      Erinnert mich doch sehr an das Sofa, das Douglas Adams nicht mehr das Treppenhaus bewegen konnt. Ich habe vergessen, in welchem Buch das war. Aber ich denke das muss in einem seiner Bücher über Dirk Gentley gewesen sein.

        @futurebird looks like a variation on the "klotski" puzzle, so there probably is some math on that

            @futurebird@sauropods.win I guess the reason it's hard is because the single square pieces are distracting. A totally consistent graph muncher algorithm would find the solution eventually, but a human working quickly on intuition is going to be subject to misdirection and red herrings and bad intuitions due to the way we think quickly.

            I think it's interesting from a psychology and cognition standpoint, beyond just the surface level "fast thinking mistakes" thing, there's something really interesting going on with how cognitions blend unconscious intuition and conscious reasoning 🙂

                    @futurebird I don't do math, but am pretty good with visual problem solving. I've made a replica on paper and am trying it now. Like you, I was able to get it to the lower right corner easily, but am currently stumped. Some instinct tells me that getting the lamp and clock on opposite sides of the field would help, but I don't yet see how to do that (or how exactly it would help).

                      @futurebird A lot of work has been done on Klotski type games. The reason one possible outcome seems harder than another is because the possible paths in the moves graph to get to that outcome are more hidden with more branch points that foreclose them (like a system of roads that it's easier to get lost on). Here's a neat visualization of how these games work.

                        I have an old game I've copied from phone to phone called "Unblock Me" which is basically this.

                        You get into a groove eventually and it just happens.

                        The Wikipedia article doesn't really explain how or why. https://en.wikipedia.org/wiki/Sliding_puzzle

                          @FediThing @futurebird @TerryHancock It's experience. When you work with materials and your hands, you come to understand all kinds of physical properties. Woodworkers understand grain. Spinners understand how different kinds of fibers will split or combine. Repeating again and again with slight variations each time develops instinct. Instinct is highly internalized knowledge that you know with your body and brain together.

                                That seems way too hairy. It can be seen as just a game tree with a set of possible moves. You cache positions so you can detect loops*, and then you just search the resultant tree.

                                Folks who wrote chess/othello sorts of games could program this up real quick.

                                * A move that returns to a prior position forms a loop, and thus can't be making progress towards an end state.

                                    @Bumblefish @FediThing @futurebird @TerryHancock not just material! Spotting spambots and sock puppets (or lately, chatbot shite) was never about "rules" or "tells". You can just SEE it and you can't really explain how

                                    And when I worked with complex records, I made such a habit of checking over the whole record (instead of just changing the little part of it some form or other instructed), that after a while I could often tell that something was wrong with it just from a couple of glances, without consciously knowing why

                                      @Bumblefish @FediThing @futurebird @TerryHancock probably the part of me that did mental arithmetic to pass the time during ad breaks as a kid (before years of shitty maths teachers ruined it) was lighting up and detecting that something literally didn't add up

                                        @FediThing @futurebird @TerryHancock It's experience. When you work with materials and your hands, you come to understand all kinds of physical properties. Woodworkers understand grain. Spinners understand how different kinds of fibers will split or combine. Repeating again and again with slight variations each time develops instinct. Instinct is highly internalized knowledge that you know with your body and brain together.

                                        @Bumblefish @FediThing @futurebird @TerryHancock And also: there are physical things we know how to do, without knowing how we know. For example, if you practise singing in tune, you learn to tense precisely the right muscles in precisely the right way to get the right pitch, probably without even having any idea which muscles they are. Your brain just knows "to make this sound, I send out these signals via those nerves", and you couldn't work out logically how much muscle tension to use.

                                          @Bumblefish @FediThing @futurebird @TerryHancock Similarly with playing in tune on a violin: your fingers have to be a the right distance apart, which feels a certain way, and by practice you sort of calibrate the feeling. But once you've got it, trying to analyse instead of trusting the feeling will probably make you play the note out of tune.
