## Solitaire of Life

A forum where anything goes. Introduce yourselves to other members of the forums, discuss how your name evolves when written out in the Game of Life, or just tell us how you found it. This is the forum for "non-academic" content.

### Re: Solitaire of Life

`x = 11, y = 9, rule = LifeHistory7.C\$.A4.C.A.C\$A.C3.C2.CA\$.C3.AC\$4.C4.2A\$4.C4.C\$3.AC.AC.A\$2.A2.C2.A\$2.CA2.AC!`

I think that’s optimal, well done.

Can I post a puzzle, since no one else seems to be posting one?

### Re: Solitaire of Life

`x = 5, y = 5, rule = LifeHistory.2A\$.A.2A\$A3.A\$2A.A\$2.2A!`

I myself will offer a 36-cell solution, the smallest I can get:
`x = 11, y = 11, rule = LifeHistory2.C\$.C.C4.2C\$.C.C3.C2.C\$2.C.2A2.2C\$4.A.2A\$3.A3.A\$3.2A.A\$.2C2.2A.C\$C2.C3.C.C\$.2C4.C.C\$8.C!`

After manually inspecting this one, I noticed that the red cells have to be dead.
`x = 7, y = 7, rule = LifeHistory2.3D\$.D2A2D\$2DAD2AD\$DA3DAD\$D2ADA2D\$.2D2AD\$2.3D!`

As a result, to prevent birth on blue, four cells will always be on:
`x = 7, y = 7, rule = LifeHistory2.3DC\$CD2ABD\$DBAD2AD\$DA3DAD\$D2ADABD\$.DB2ADC\$.C3D!`

All solutions must have at least 24 cells.
`x = 7, y = 7, rule = LifeHistory2B3DCB\$CD2A2DB\$2DAD2AD\$DA3DAD\$D2ADA2D\$B2D2ADC\$BC3D2B!`

Four cells to prevent birth on blue:
`x = 7, y = 7, rule = LifeHistory2.3DC\$CB2ADB\$2DAD2AD\$DA3DAD\$D2ADA2D\$.BD2ABC\$.C3D!`

Such cells will touch white, so four more cells are required to stabilize the white cells.

LLS verifies that this the unique optimal solution.

### Re: Solitaire of Life

Almost posted this as a puzzle, but then I was doing my preparative analysis, and then this happened:
`x = 8, y = 8, rule = LifeHistory3.3D\$2.D2A2D\$.2DAD2AD\$D2A3DAD\$DA2D2A2D\$2DADA3D\$.D2A2DED\$2.5D!`

What's the highest minimal stabilization to unstabilized ratio possible? I managed to get 3 in that last puzzle.
This will be the next puzzle with 14 cells, then...
`x = 7, y = 7, rule = LifeHistory3.3D\$2.2D2AD\$.D2ADAD\$2DA3DA\$DA2D2AD\$D2ADA2D\$.2DA2D!`

I managed to find a 38 cell solution.
`x = 11, y = 11, rule = LifeHistory9.C\$2.2C4.C.C\$.C2.C3.C.C\$.C.C2.2A.C\$2.C.2A.A\$4.A3.A\$3.A2.2A.C\$3.2A.A2.C\$.2C2.A2.C\$C2.C2.2C\$.2C!`

I just try to make everything connected pre-blocks, because those tend to be excruciatingly hard.
Now for my analysis!

Every solution will have at least 24 cells.
Three are forced on. Three are needed to stabilize the two in the upper left, four to stabilize the one on the lower right:
`x = 9, y = 9, rule = LifeHistory2.3B\$2.BC3D\$3B2D2AD\$BCD2ADAD\$B2DA3DA\$.DA2D2ADE\$.D2ADA2DE\$2.2DA2DC\$5.2E!`

This would be a lot more fun if you hadn't done half the solving already

31. It doesn't improve the previous one, but is still worth noting, if only for the 16-bitter:
`x = 12, y = 11, rule = LifeHistory7.A\$7.2CA\$10.A\$.2A.CA3.2C\$C.A.A.A2.C\$C5.C4.A\$.2CA2.CA2.2A\$3.C2\$6.CA\$6.CA!`
