Catagolue[note 3] is an ongoing distributed census of naturally occurring ash objects conducted by Adam P. Goucher, started in late February 2015. The census is primarily focused on asymmetric soups in Conway's Life, but supports arbitrary outer-totalistic and non-totalistic rules and a variety of symmetries.[endpoint 1] Over 100 users have contributed to the census.

The results are obtained by evolving random soups of size 16×16 with density 0.5 in an infinite planar universe; as of January 8, 2024, at least 501,395,668,884,543 soups have been investigated by the census's participants, yielding a total of at least 5,672,370,87,092,536 objects of 495,474 distinct types. Submissions of new results (called "hauls") are subjected to both statistical tests and peer-review by other participants before being committed to the census.

Catagolue is primarily fed by apgsearch, including apgmera (apgsearch 3.x) and apgluxe (apgsearch 4.x) as well as Aidan F. Pierce's hacked version supporting arbitrary non-totalistic cellular automata. Each resulting object is identified by apgsearch by its unique apgcode; the Catagolue website gives overviews over the various classes of objects found, and provides further information as well as sample soups for each object.[endpoint 2] A simple text-based interface for querying sample soups, including their owners, also exists.[endpoint 3]

History

Main article: History of Catagolue

Catagolue became operative on February 20, 2015.[1] The B3/S23/C1 census reached a total of one trillion objects on April 24, 2015[2], ten trillion objects on September 2, 2015[3], 100 trillion objects on June 20, 2016[4], and 200 trillion objects on May 16, 2017.

A variety of notable natural patterns have been submitted to Catagolue:

  • The first known natural occurrence of a nonstandard spaceship was found during alpha testing of apgsearch. The soup, which produced an LWSS on HWSS 1, was submitted to the conwaylife.com forums on August 26, 2014 by Adam P. Goucher.[6] Many other nontrivial spaceship flotillae have since been found.
  • The first known natural occurrence of a puffer other than the block-laying or glider-producing switch engine, a p1152 made from two switch engines dubbed the pony express, was found in September 2015.[7] Other objects found by apgsearch in asymmetric soups are smiley, Elkies' p5, phoenix 1, and six occurrences of the Coe ship.
  • The pufferfish was discovered in the ash of a symmetric soup.
  • A copperhead emerged from a D2_+2 soup in April 2016 soon after its initial discovery by zdr, followed by a second one in June 2016 and a third in August 2016; two more copperheads were found in D4_+4 and D8_4 soups in November 2016.
  • 112P15 was first discovered in the ash of a symmetric soup in April 2016.
  • Rich's p16 was first discovered in the ash of a symmetric soup in July 2016.
  • thunk's discovery of a period 28 pre-pulsar-shuttle variant enabled the construction of smaller (in terms of minimum population) period 26 and period 28 pre-pulsar-shuttles.

Sample soups submitted to Catagolue have also led to cheaper glider syntheses for many patterns, including tumbler, eater 2, and smiley.

In addition to asymmetric (C1) soups, Catagolue also collects census data for symmetric soups of the following types:

  • C2_1, C2_2, C2_4: 180° (two-fold) rotational symmetry
  • C4_1, C4_4: 90° (four-fold) rotational symmetry
  • D2_+1, D2_+2: reflectional symmetry along an orthogonal line
  • D2_x: reflectional symmetry along a diagonal line
  • D4_+1, D4_+2, D4_+4: reflectional symmetry along two perpendicular orthogonal lines
  • D4_x1, D4_x4: reflectional symmetry along two perpendicular diagonal lines
  • D8_1, D8_4: reflectional symmetry along four orthogonal/diagonal through a common center

Furthermore, the following pseudo-symmetries are used for asymmetric soups of different sizes:

  • 8x32, 4x64, 2x128, 1x256: for 256-cell soups of size 8×32, 4×64, 2×128 and 1×256

8x32 was one of the initial (pseudo-)symmetries the site handled; support for 4x64, 2x128 and 1x256 was added in August 2017.[8]

Inflation of a toy 4×4 soup.

All symmetries can be "inflated" using the "i" prefix, replacing each cell in the sample soup with a 2×2 alignment of cells in the same state and resulting in soups of size e.g. 32×32 for iC1 instead of 16×16 for C1. Multiple "i" prefixes can be stacked to "inflate" cells to 4×4, 8×8, etc.[9]

The 25pct and 75pct pseudo-symmetries were used in the past to investigate soups with initial densities of 0.25 and 0.75 respectively, but they fell into disuse and are not supported by the current version of apgsearch, apgmera 3.x.[note 4] Other pseudo-symmetries such as 25p, 32x32, 1x256X2+1 etc. have been used, but are not considered standard. Catagolue encourages users to use designated "test" symmetries to test modifications to the client,[10] and can be used to as a generic pattern inventory using arbitrary symmetries and rules (see below).

Hauls for higher symmetries are subject to statistical verification before being committed, but not (with some exceptions) to peer review.[note 5]

Results in higher symmetries

As of March 12, 2024, at least 1,075,698,622,453,873 soups have been investigated in higher symmetries[note 6] of B3/S23, yielding a combined total of at least 15,217,000,000,000,000 objects of 3,887,077 distinct types, including:[note 7]

Patterns seen but not properly recognized by the client (see Limitations below) include a D8_1-symmetric variant of the p29 pre-pulsar shuttle.

Slow salvos

Catagolue started collecting data on objects created by slow salvos on January 13, 2017, using the SS pseudo-symmetry; data was generated by the HoneySearch utility.

As of April 27, 2019, slow salvos have yielded a total of at least 556,856,180,742 objects of 2,667 distinct types, including:

Other rules

Main article: List of rules investigated on Catagolue

Catagolue supports arbitrary outer-totalistic rules and non-totalistic rules (in Hensel notation), as well as Generations and Larger than Life rules, along with indirect support for Margolus rules (specifically block cellular automata) using inflated soups on specific rules; in practice, only non-exploding rules can reasonably be investigated unless a certain symmetry can be assured to never explode. 24,239 rules have been looked at as of January 8, 2024. The Moore neighbourhood is currently the only supported neighbourhood, although rules with the Von Neumann neighbourhood can be simulated by Moore rules.

Rules investigated on Catagolue include multiple close Life variants:

Other notable rules investigated include:

Catagolue as a generic pattern inventory

Although primarily used for soup-searching in practice, Catagolue can be used as a generic pattern inventory/warehouse, as shown by e.g. the slow salvo data it collected (see above). Users are encouraged come up with their own rulestrings, symmetry types, and object codes:

[Catagolue] basically accepts anything that you choose to pass off as a rule name, symmetry type, and apgcode. If you make a search program which produces haul files for your favourite CA, then Catagolue will happily build a distributed census [...]
The search program needn't even be a soup search: if you have a depth-first search program such as gfind or zfind, and you have a correspondence between positions in the search tree and alphanumeric strings (where prefixes correspond to ancestors), then you can conduct a distributed search for (say) width-20 c/6 spaceships using the existing Catagolue framework. If you incorporate all of zfind's command-line hyperparameters (period, offset, memory size, etc.) into the beginning of this string, then you can simply have a 'symmetry' called zfind whose tabulations will include things such as xq7, xq10, xq19 (potentially!), etc. And this will work without changing Catagolue in any way.
Adam P. Goucher[12]

Contributor engagement

Contributors to Catagolue have user pages tracking their contributions to the main Conway Life census, B3/S23/C1.[endpoint 4] In addition to providing an overview of number of objects submitted recently compared to other users, user pages list important discoveries and awarded badges.

Users are credited for discoveries if they find one of the first 20 occurrences of an interesting object: any spaceship (other than the glider), any oscillator, any linear growth pattern, or any sufficiently small (14-bit) or large still life. Certain other types of still lifes, such as Eater 2 precursors, are also credited.

The following badges are currently awarded for contributions to B3/S23/C1:

Interesting new objects are additionally announced on Twitter by an unofficial Twitter bot.

Backups

Catagolue census data for the main Conway Life census, B3/S23/C1, is backed up remotely every day at 17:29;[note 12] the first such backup was made on September 24, 2015. For other symmetries or rules, a remote backup may be instigated manually by calling the backupcron endpoint,[endpoint 5] with the desired rule and symmetry. Remote backups can be viewed by appending the date to the main census URL.[endpoint 6]

Local backups of Catagolue census data may be made by calling the textcensus endpoint for the desired rule and symmetry.[endpoint 7] The list of objects returned can be sorted by object frequency[endpoint 8], but this should be avoided when possible to reduce server load.[14] It is also possible to restrict objects returned to a certain prefix,[endpoint 9], or to query the number of objects, grouped by prefix and including a total.[endpoint 10]

Limitations

Server

Catagolue does not accept hauls exceeding 1 MiB; additionally, hauls must contains a minimum of 10,000 soups or 250,000 objects.[15]

Client

Although the apgsearch family of programs has bespoke support for flotillae composed of two standard spaceships in Conway's Life, it can fail to properly separate larger non-interacting groups, or groups of any size in non-Life rules. Pseudo still lifes composed of many constituent parts may also fail to be separated properly.[16]

The maximum period for spaceships and oscillators is 1,000 in apgsearch 1.x, 4,000 in apgnano (apgsearch 2.x), 1,280 in apgmera (apgsearch 3.x), and 1,048,576 in apgluxe (apgsearch 4.x); higher-period objects are classified as PATHOLOGICAL. The maximum bounding box for any spaceship, oscillator or still life is 40×40; larger objects are classified as ov_ (oversized). High-period linear-growth patterns may not be identified and instead reported as zz_LINEAR.

Web frontend

Although Catagolue verifies that an object in a given rule behaves as specified by its code, the site makes no attempt to reject non-canonical codes (e.g. xp2_222 rather than xp2_7 for the blinker); furthermore, the site accepts various anomalous prefixes (e.g. xp0 and xq0). No attempt is made to normalize or reject anomalous rules (e.g. "b33s23"), although a feature is planned to clear out censuses which do not adhere to the Catagolue naming conventions.
