Can someone please ELI5 what this means? Thanks in advance.
Someone figured out how to create a glider that starts and ends as a long string of cells on a single line. Gliders are figures in the game of life that move themselves in a direction by repeated patterns that result in movement. For more game of life/glider context you can read the pretty decent Wikipedia articles: Conway's game of life: https://en.wikipedia.org/wiki/Conway%27s_Game_of_Life Gliders: https://en.wikip…
Me: oh cool, this is interesting, I don’t quite understand what exactly that means, let me read the thread to learn more… The thread: > Replacing ECCA1 by version with step after the direction change could save something like 1% of the ecca1 bits size. Compiling agnosticized program instead of fixed lane program by ecca1 could save something like 1% as well (just guesses). Build of smaller ECCA1 would shorten binary…
Notably it only fits within a 1 cell high bounding box during at least one of its phases, not all.
I'm really charmed by the linked thread and all the passion and work it belies. Congrats to those involved!
The result is easily verify-able, yet the techniques to design such a glider are very complex and some might not have been discovered yet.
glider is a specific spaceship, but name for "moving pattern" is spaceship
So it starts as a line, explodes into a huge 2D complex mess, and eventually, after many generation, returns to form the same 3.7B cells long line? That's kind of amazing. I wish someone unpacked the units of abstraction/compilation that must surely exist here. Surely they aren't developing this with 1 or 0 as the abstraction level!
See here: https://conwaylife.com/forums/viewtopic.php?f=2&t=2040&start... It’s also a relatively sparse line, as the number of live cells is less than a hundredth of the line’s extent: https://conwaylife.com/wiki/Unidimensional_spaceship_1
Wow this seems very interesting! Can we get a TLDR of how this was achieved?
While I understand very little of it, it is still very enjoyable to read the details further in the thread at https://conwaylife.com/forums/viewtopic.php?&p=222136#p22221... >>> Unidimensional spaceship can be interpreted as a demonstration of the progress of recent years in slow salvo technology and the various arms that use it. The project uses 4 construction arms, with the last three sharing principles with the ar…
Is there a visualization of the glider in the thread? Would love to see how it evolves with one dimension being time.
After the first step it isn't 1D any more, so I don't think that visualization is possible
