Re: Help me finish this c/8 search

Matthias,

What is the current status of the search? I somehow lost the overview.

I understand that the width 19 search as well as the width 21 gutter search produced no ships, but promising partial results. Correct?

Re: Small Spaceship Syntheses

Without taking a closer look, the synthesis for 30P4H2V0.4 might profit from the newly available tools. Did anyone try to improve the synthesis for pushalong 1?

Re: A new spaceship search approach

Would it be possible to search for ships with two lines of on cells in the middle?

These would be a good starting point for grey ships.

Re: Spaceship Discussion Thread

Congratulations! Great to finally see progress in diagonal c/4 puffers after so many years! By now it should be relatively easy to create a script that simulates an incomplete puffer engine to get useful candidates. I remember that finding the first completion of the engine was quite tedious, so you...

Re: Thread For Your Accidental Discoveries

That reaction is one-sided and therefore potentially interesting for a caterpillar LWSS synthesis...

The lifewiki actually shows the block variant as an example for a one-sided glider synthesis.

Using ML to synthesize complex constellations

Re: Loafer rake made with copperhead technology

Great work!

My impression is that this area is rather unexplored as of now. So I’d like to see more rakes from non c/2 technology producing non c/2 output. How about an analogous 2c/7 rake for loafers based on the weekender distaff? Similar thing based on c/6 technology?

Here is an old example of a2c/4 against the grain spaceship which shows how to flexibly increase and decrease the width of the grey part. This can be used inversly for the crawler. However, it is currently not clear to me how this will give a back corner for a 2c/4 crawler. x = 154, y = 296, rule = ...
