Book on OCA

Post by H. H. P. M. P. Cole » November 6th, 2023, 4:29 am

dvgrn has written down suggestions on his Lifewiki page on a book on OCA. (Volume 9)

This is the ONLY book I can contribute to as I am terrible at vanilla CGOL (fun fact: I have posted no less than four failed SKOPs on the forums).

Any topic ideas? Here's my two cents:
- Life-like CA (mention Heudin's paper on B3/S13, Eppstein's Searching for Spaceships, etc.)
- Hensel notation
- Rulespaces (include graphics)
- Close life variants (incl. tlife, LeapLife)
- Rulegolfing (incl. EPE)
- 'Engineering-friendly' CA (incl. Snowflakes, Dominoplex)
- Margolus rules and emulation
- SMOS, SMOSMOS
- Other neighbourhoods (hex, triangular)
- Laregr-than-Life (incl. CAViewer)

We should also get rowett to support some of these. I have posted a big fat list of suggestions including my own R3 Cross isotropic notation, Durnak-Cole.

Exemplar rules to add:
Life, HighLife, Pedestrian Life (four high-period mechanisms), Grounded Life, Seeds, LowLife (Heudin's rule), Flock, Morley, tlife, Leaplife, High Seas, AforAmpere's 7 3-cell ship rule, High Seas, Eatsplosion, Snowflakes, Dominoplex, Brian's Brain, FWKnightship's SMOSMOSMOSMOS rule, Bosco, Factorio, Carter Bays' 3D rules, Yoel's self-complementary hexagonal rules

Also mention like the 'one object only' game, my 'maximum number of 4-cell objects' game, as well as other games which are nonetheless OCA related.

Any other suggestions?

I'll be willing to do the chapter/section on LtL. Anyone into the challenge of making the rest of the book?

You can credit me in the book as Harfordson Parker-Cole.

"Cellular automata" is incredibly vast. Even for plain Life, one "subtopic" could fill a book (see for example Tutorials/Coding Life simulators). One other possibility (this was mentioned somewhere on the forum) is a collection of articles on various topics. This could be in the spirit of Game of Life News:
Sprouts and parasites (2011-01-07)
New p5 Herschel technology (2008-02-01)
Period 16284 Agar (2006-07-15)
127:1 B3/S234c User:Confocal/R (isotropic CA, incomplete)
Unlikely events happen.
My silence does not imply agreement, nor indifference. If I disagreed with something in the past, then please do not construe my silence as something that could change that.

Not sure if this is the right referent, but one thing that's in the works is a new "collection of articles on various topics" by Prof. Andrew Adamatzky.

At the moment there are three CGoL-related chapters that might make their way into that book -- though in each case, there's more work still to be done and time is starting to run out for the official December 15th deadline for submission:

1) a summary of the original RCT15 mechanism;
2) a summary of the still-in-progress optimized RCT15 design;
3) an article on the proof of CGoL omniperiodicity.

If someone wants to put together a chapter on an OCA topic, it might also be accepted -- though obviously that's not guaranteed! Adamatzky's collections are more oriented toward academia than the usual blog-based or LifeWiki-based popularizations, so it would require some negotiation to figure out what OCA topics would be interesting for the collection. Something like a survey of self-constructing Geminoid spaceships across various rules might work -- like AforAmpere's tiny Orthogonoid and others. (?)

Sweet. I am also working on Conway and friends story mode, which is like the book but vastly more accesible and with OCA.

I mean no harm to those who have tested me. But do not take this for granted.
