OCA DOTY 2024 Voting
Posted: June 10th, 2025, 7:23 pm
This is the voting thread for 2024 OCA Discovery of the Year.
The voting period ends on July 31st 23:59 UTC. Any vote after the time will not be accepted.
Nomination thread here.
01 B2n3-enqy4cijrwyz5cinqy6kn78/S01e2ein3eikry4-ciry5-aeky6ein7e8 and its variants. The original rule has tons of high-period oscillators (including a natural p37), often with simple predecessors. (hibiscus)
02 New spaceships in life-like cellular automata. Highlights include a spaceship in B35/S46, one of Eppstein's Most Wanted (May13), a 2c/11o spaceship in B356/S456, the first spaceship of that speed to be found since 2017 (hibiscus), a (2,1)c/6 spaceship in Dance, and several spaceships in B3567/S14578, the rule with the most spaceships (H. H. P. M. P. Cole), bumping the speed count to 25 different spaceship velocities. (Many)
03 Omniperiodicity. No general thread for this entry, but in 2024 several rules were proven omniperiodic, including Dancing by the slug, Bazaar, and a few other rules. (Many)
04 Speciation - The rule with the 2nd most number of NRSS of any INT rule. The rule with the most number of NRSS is a relative of this rule. (NimbleRogue, H. H. P. M. P. Cole)
05 Project Omniraumschiff - A collaborative effort started by hibiscus which attempts to gamify the process of shipsearching and increasing the number of spaceships known in Eppstein's Glider Database. (hibiscus et al.)
06 BasiKnight, a versatile rule with a very small (2,1)c/6 spaceship. (islptng)
07 Foam rules, a rulespace with many spaceships in it having very high periods. (NimbleRogue)
08 For lack of a better name, sideways mealworms, a series of ships that consist of an XOR replicator on the side of a rectangle with the ship moving perpendicular to it (NimbleRogue)
09 Ada's rule, a surprisingly interesting rule for its simplicity of description.
10 A 106c/23932o and 64c/9896d in Sticky. (islptng)
11 Various replicators in universal construction wire rules. (islptng)
12 One-cell Sir Robin gun in a 33-state CA. (islptng)
13 Various RuleLoader emulations of various rules and rulespaces, including a 17-state Moore RuleLoader solution for all R2 Moore 2-state rules, 77-state vN RuleLoader solution for Factorio and Life simulation with single cell representing 2x2 areas. (islptng)
14 Photons10, a collaborative rule project. (CARuler)
15 Several new 3-state CA with interesting properties. (FWKnightship)
16 The CataProp family of rules. (b-engine)
17 The Life-like p1 photon project to determine which Life-like CA support period-1 photons. (Matthias Merzenich, Keith Amling)
18 High period photons with periods above what has previously been possible to search for, found with a new multi-period photon searcher program. (mystical)
19 A knightrake and knightship in B25678/S4578, the first Life-like B2 rule to contain a knightrake, and the second to contain a knightship. (Matthias Merzenich, LaundryPizza03, Dmitry Maitak)
20 A c/3 diagonal moon rake in Seeds. (Keith Amling)
21 A rule with 24 reduced slopes of elementary ships. (FWKnightship)
22 The first list of apgsearchable OT rules. (H. H. P. M. P. Cole)
23 An oscillator in Seeds that is "as close to being isotropically endemic to Seeds as one could get". (Keith Amling, confocaloid, H. H. P. M. P. Cole)
24 Discoveries in the Hexagonal INT rule B2o45/S2o45H. (Many)
25 A minor lemma to create & validate Hashlife-friendly W110 agars. (Naszvadi)
26 Asteroids, a near-explosive rule featuring six natural spaceships of five speeds and a c/4 growth pattern that computes OEIS sequence A133463.(R2INT)
27 A ship made out of slightly offset oscillators, where for most of its lifetime it's just a rectangle with a p550, and p446 oscillating reaction on either side that slowly goes more and more out of sync until it breaks. (NimbleRogue)
28 snrship, a rule with many exceedingly high period ships. (Moosey)
29 7-engine corderization of a (21,6)c/177 puffer in B37c/S238. (Naszvadi, AbhpzTa)
30 Guns in B3/S234z based on 4G to 6G and 11G to 12G overunity reactions. (AbhpzTa, confocaloid)
31 The first orthogonoid in Generations, based on an orthogonoid puffer by cvojan. (iddi01)
32 40c/69704o orthogonoid in Duck and Frog, using a very minimal single-channel kit. (Chai)
Vote only for the patterns you like, and give each of them 1-5 stars depending on how much you like them. You can vote for your own nominations if you want. Here is an example vote:
[Example removed because it doesn't count as a vote]
It's better to put your votes in a code tag and don't forget the leading zero for single-digit numbers.
The voting period ends on July 31st 23:59 UTC. Any vote after the time will not be accepted.
