如何找到滑翔机合成这样？枚举？

I'm not sure what you're trying to ask-- no spaceships are synthesized in the RLE you posted.

But in general, glider syntheses are hard to make and require quite a good bit of human intuition; see Extrementhusiast et al.'s efforts here.

Bob Shemyakin has also compiled a database of glider syntheses of still lives up to 15 (or 18) bits, which might be useful too.

Also I'd like to remind you that the official language for these forums is English. If you don't know English well enough, copy and paste machine translation (e. g. by Google Translate) along with Chinese original.

For starters, you could maybe ram gliders into arrangements of still objects until you get the results you want, then synthesise those objects in the right place afterwards with more gliders.

It's highly recommended to use the [ c o d e ] [ / c o d e ] (delete spaces) tags.
Just like this:

Code: Select all

x = 43, y = 89, rule = B3/S23

And answers to your original question:

如何找到滑翔机合成这样？枚举？
How to find glider syntheses like this? Enumeration?

可以用其他方式寻找，但是枚举能找到（接近）最优的合成。
They can be found by other ways, but enumeration can lead to a (nearly)optimal solution.
