FAQ: Is this a new discovery? Is this already known?

Post by confocaloid »

One of the most frequent (and often hard to answer) questions is "Is this new?"
The purpose of this forum thread is to collect possible answers that can be expected to be helpful.

There are many different kinds of components, reactions, patterns, and that often affects how one can look up for what is already known.
If you know an answer that isn't mentioned yet (e.g. a new pattern collection or database), please post it in this thread.

Q: I found an interesting pattern, is it already known?

A:
If you found some reaction, pattern, component and you don't know whether it is new, you can post it in Thread for your unsure discoveries. When posting, please describe the pattern and mention how it was found (for example, was it found manually, or with some search program?)

It may be hard to tell whether something is new. (However, see links below for some existing ways.) Even if your pattern turns out a rediscovery, it can be interesting to know how it was rediscovered; this can help to understand how to find more similar patterns.

It is highly encouraged to do some research to get an idea of what is already known. Here are some of the existing ways how you can look up yourself what is known about Conway's Life: Q: I found an oscillator, is it new? Is this oscillator already known?

A: Take a look at the following collections: Q: I found a spaceship, is it new? Is this spaceship already known?

A: Take a look at the following collections: Q: Where else can I look to see what's already known?

A: Here are additional links, in no particular order:

For oscillators, https://github.com/carson-cheng/newjslife/tree/main is more complete than the third bullet point you have.

Maybe also mention that new still-lives or p2 oscillators etc are not considered notable unless they do something unusual.

I added links to the "lots of spaceships" and "knightt results" collections to the spaceship section. Confocaloid, feel free to edit the wording as you see fit.

TLDR:
Q: Is this known?
A: Yes.

Technically that could be considered correct, because the person asking the question would post the pattern or reaction in question (therefore making it known to others), but I thought the underlying idea behind variants of the frequently-asked question "Is this known?" is different...

After some consideration: Updated TLDR:
Q: I found this in a soup. Is this new?
A: Very probably not.

Probably a necropost, but I have a question: How is it possible to search 209 pages of the oscillator discussion thread? Searching for keywords like the period will only reduce that number by so much.

Edit: I know the search bar exists, what I'm saying is if you simply search for a description of your oscillator like "p2 billiard table", it'll bring tens if not hundreds of results, and most of the results that show up won't be what you're looking for.

The forum search is buggy and can't meet the needs of most people here.

Additionally, it excludes things like dashes and treats them as spaces.
