I’m familiar with issues like this. Lots of copy/pasting with little edits here and there all the way down.
now implement castling in that
if that is python then makes sense
Programming chess as a single lookup table is wild
Right?
pretty sure there are more possible chess positions than atoms in the earth (universe?), so even if every atom of our planet were converted to transistors there’d be no way to fully represent all possibilities.
This was a fun one to look up. https://en.wikipedia.org/wiki/Shannon_number
It looks like the number of valid chess positions is in the neighborhood of 10^40 to 10^44, and the number of atoms in the Earth is around 10^50. Yeah the latter is bigger, but the former is still absolutely huge.
Let’s assume we have a magically amazing diamond-based solid state storage system that can represent the state of a chess square by storing it in a single carbon atom. The entire board is stored in a lattice of just 64 atoms. To estimate, let’s say the total number of carbon atoms to store everything is 10^42.
Using Avogadro’s number, we know that 6.022x10^23 atoms of carbon will weigh about 12 grams. For round numbers again, let’s say it’s just 10^24 atoms gives you 10 grams.
That gives 10^42 / 10^24 = 10^18 quantities of 10 grams. So 10^19 grams or 10^16 kg. That is like the mass of 100 Mount Everests just in the storage medium that can store multiple bits per atom! That SSD would be the size of a
smalllarge moon!i think you did the weight approximation in the wrong order, 1024 is a lot bigger than 6×1023. so you can probably double the final weight.
10^24 is a lot bigger than 6×10^23
Well yeah it’s almost double, but I wrote the comment as a mental estimation of the order of magnitude, so it doesn’t change the substance of the discussion.
I mean at the beginning I arbitrarily picked a number in that 10^40 to 10^44 range and that’s a factor of 1:10,000 rather than 1:2, lol.
Slightly less than double, actually. (Doesn’t really change the meat of the argument or anything though.)
Assuming your math is correct (and I have no reason to doubt that it is) a mass of 10^16 kg would actually be a pretty small moon or moderately sized asteroid. That’s actually roughly the mass of Mars’ moon Phobos (which is the 75th largest planetary moon in the Solar System).
I was thinking of 10^16kg diamond storage inside a larger SSD that’s the size of a large moon, similar to how a real SSD has data stored in tiny little slivers of silicon inside a much much larger device.
I should have explained that one better. It’s easy to imply such details to keep text shorter.
Out of curiosity, why did you say planetary moon? Is there any other kind?
Dwarf planets sometimes have moons (e.g. Pluto)
Some large asteroids have moons too.
this leads to the question: are they still considered a moon when the barycenter is in the space between them?
valid chess positions is in the neighborhood of 1040 to 1044
Lol, big board you’re playing with…
A position is the arrangement of all the pieces on the board.
If you don’t limit it to valid positions/arrangements it’s like 10^120. Closer to the “number of X in the observable universe” caliber of number.
So I think I was wrong, but you are too lmao.
10120 is the number of valid game-trees, or valid ~80 move games.
The much smaller number I quoted above, though, IS the valid positions, I was thinking it was actually the trimmed down “truly valid” game-tree sequences.
Isn’t math fun? Limitless ways for us to be wrong!
I would have probably done it in my high school programming class to be funny and also fuck with my teacher, because they were an asshole.
Honestly back when I was a kid this is how I thought games were made, every possible image of a game was already saved and according to your input it just loaded the next image.
I stopped thinking that with 3d games
This is what I believed. And I tried to trick the game by doing movements and inputs no one could have planed. Never outdid that planning somehow. They were on to me!
Those shitty old tiger hand holds kind of worked like that.
It does work like that a little bit, like with sprites they’ve often hard-coded the frames of animation, so when you push a button it loads the correct image, like Mario’s jumping frame with his hand in the air. But there are such things as tilesets, and sprite positions, and all that good stuff.
I thought that they were managing that stuff on a per-pixel basis, no engine, assets, or other abstractions, just raw-dogging pixel colors.
And before I even played video games at all I was watching somebody play some assassin’s creed game I think and I thought the player had to control every single limb qwop-style.
In the first few Assassin’s Creed games, they did use the idea of a Puppeteer system for the control scheme, although it wasn’t physics-based or anywhere as hard QWOP. Each face button of the controller performed actions associated with each limb, and the right trigger would swap between low profile actions and high profile actions.
In the top right of the screen, there was always a UI element showing what the buttons did at that moment in that context, which might’ve been part of why you thought it was like that. It’s not exactly what you were thinking of at the time, but you were closer than you realise.
Not quite “Time Killers” level of limb to button assignment, but a line that I had not drawn in the AC control scheme!
Even with 2D games that’s basically impossible. Only time it could work is with turn based games and then…you end up with this post lol.
I see you’ve never played “Dragon’s Lair”, where every scene was cell animated and the player “chose” the path that the animation would take.
LOL, I’ve actually heard of it, but I have not played it. Ofc that game never even crossed my mind when writing my comment haha. I suppose choose your own adventure style books also fall into this category.
Space Ace!
That one ran on a laserdisc, right? Like a CAV disc so it could very quickly move the laser to one of a couple of places for basically a win/lose decision, overlaying some graphics over top for the game UI?
I remember having a thought one day as a young kid while interacting with a DVD main menu (the kind that had clips from the movie playing in the background, and would play a specific clip depending on what menu you went in to).
“This is basically how video games work, there’s a bunch of options you can choose from and depending on what you do it shows you something. Videogames are just DVD menus with way more options.”
I grew up to not be a programmer.
The game Myst actually worked kind of like a DVD menu with more options.
Instead you are a choose-your-own-adventure author
Close, I DM’ed a short-lived DnD campaign a year ago.
Its not terribly far off from pre rendered or FMV games like Myst are doing it.
I grew up mostly with the PS2 and above and I thought the same thing 😅. I did think there had to be a better way though
I remember speculating as a (small) kid that the AI soldiers in Battlefront II’s local multiplayer might be real people employed by the developer. Not the brightest child was I.
I remember as a kid seeing my older brother talk to people on a mic and thought he was talking to the characters in the game
As a middle schooler I used Power Point to make FMV games for my friends and classmates, and it was basically this. Just, like, SO MANY slides
AI has probably finished this game by now.
And still lost.
Laughable for chess, but essentially how Steve Mould played tic tac toe using synthesized DNA.
This is very inefficient, they should be using a switch case.
For efficiency you should you GOTO, so you can join trees that end up in same position.
Like those create your own adventures books.
This is where you’d normally go “there must be a better way…”
Not some people.
This reminds me of one of my very first programs, a tic-tac-toe game I wrote in high school. It displayed hardcoded grids of Xs and Os and blanks very similar to what’s shown here. This approach worked because of the much more limited move possibilities. The program could always win if it made the first move, and always win or tie if the human moved first, depending on if the human made mistakes. I wish I still had the code.
Did the program cheat? Tic tac toe is a tie if opponents play correctly.
I’m probably remembering it wrong, it was a long time ago. It definitely always either won or tied but could never lose, because it knew the right responses to every move. No, it didn’t cheat lol.
How do you define cheating in such a simple game?
Placing moves in invalid locations, passing a turn, or making multiple moves on one turn?
There are no invalid locations in tic Tac toe, passing a turn provides no advantage, I suppose you could take extra turns to cheat.
Are they trying to code every possible chess position??
The implication is that the person in the meme is
Found the guy who passed the test with
printf (" *\n **\n ***\n ****\n*****\n);This is supposed to be a joke but sadly a lot of beginner tutorials on coding Tic-Tac-Toe teach this
They are doing it dumb. You can text output chess but you just need to keep track of where the pieces are in code, then when you are ready to output, place the characters. Saves so much time. /s
