I hope this is original. The game's goal is to find the smallest still-life stabilization for a collection of cells, with all pre-placed cells having 3 or less neighbors.

The game has been proposed by me in 2015, in our Chinese forum.

The Chinese sentence

Code: Select all

在左图中添加尽量少的格点，使得它成为稳态:
我的最好方案如右图，为9个格点。

means

Code: Select all

Add cells as less as possible to stabilize the pattern in the left into a still-life:
The best I can achieve is shown in the right, with 9 cells.

I think 格点 should be 细胞

How about this simple pattern

Code: Select all

x = 4, y = 4, rule = LifeHistory
2bo$2o$2b2o$3bo!

28, I barely tried:

@danny, I think this round goes to you.

53 was ridiculously difficult to beat, but here's 51:

Code: Select all

x = 20, y = 18, rule = LifeHistory

Maybe it can still be improved?

[BlinkerSpawn]

The best I had was this similar solution, also 43 cells, and I don't see any way to reach 42:

Code: Select all

x = 12, y = 12, rule = LifeHistory
3.2A$2A2.C$A.2C$2.C4.CA$2.C2.C2.A$3.4A.C.AC$ACA4.CA2.C$A2.2AC3.C$2.C

I'll let gmc_nxtman submit the next puzzle.

Add a little here, take away a little there... how about 39?

#C [[ THUMBNAIL THUMBSIZE 2 ]]

There's at least a three-cell improvement still, that I've left for someone else.

[Redstoneboi]

you mean this one

Code: Select all

x = 13, y = 9, rule = LifeHistory
.A8.2A$C.A3.2C2.C$A.A2.A2.A.A$.AC.C.A.C.2C$3.C2.C2.C2.A$3.C.AC3.CA$.C
A.C$.C2.C$2.2A!

[dvgrn]

you mean this one...

Yup, exactly. But then with a little more fiddling around, a 35-cell solution turned up:

Code: Select all

x = 13, y = 9, rule = LifeHistory
10.2A$CA4.2C2.C$A2.A2.A.A.A$.AC.C.A.C.2C$3.C2.C2.C2.A$3.C.AC3.CA$.CA.
C$.C2.C$2.2A!

[gmc_nxtman]

I have not verified, but I believe 35 cells is minimal.

[Hunting]

How about this puzzle

Code: Select all

x = 5, y = 3, rule = B3/S23
obobo2$o!

[Saka]

7 cells

3.2A$C.C.C$CA!

[gmc_nxtman]

Saka, I think the cells in your version are incorrect. If I have it right, I can't see a way to get smaller than 10 cells:

Code: Select all

x = 8, y = 4, rule = LifeHistory
2.A3.A$.C.C.C.A$A.A3.A$.C!

[77topaz]

Yeah, Saka's "solution" misplaced one of the cells from Hunting's original pattern.

Sorry... When I click submit, I don't remind that I misplaced a cell at first.(I'm away from Golly, so I just type the RLE with my hand) Then I edited that comment. sorry for that!
