Its population is much less than that of the Speed Orthogonoid. It travels orthogonally and is adjustable so that its speed can become arbitrarily close to c/2. This project continued 2022's increased focus on the discovery of new oscillators, partially to work toward filling in the remaining unknown oscillator periods to finally prove Life to be omniperiodic.Ī pattern made entirely of XWSSes that synthesises a reflected and translated copy of itself. Thus it is an orthogonal spaceship travelling at a speed of 30985960c/144171206.ĭavid Raucci, Mitchell Riley, Luke Kiernan, iNoMed, et al. The number of gliders was also reduced from its previous value of 17.Ī pattern made entirely of gliders that synthesises a reflected and translated copy of itself. Goucher, Pavel Grankovskiy, Simon Ekström, Dave Greene, AlbertArmStain, Oscar Cunningham, Chris Cain, dani, and Goldtiger997Ī concrete construction demonstrating that any glider synthesis can be reduced to use just 15 gliders. These discoveries include an unsynthesizable still life and unsynthesizable p2 oscillator, both based on "self-forcing" agars, a generalized solution to the grandfather problem (patterns that have n-tick predecessors but no (n+1)-tick predecessors), and American Dream, a finite pattern with an infinite-population predecessor but no finite-population predecessor.ĭaniel Vargas, Adam P. (Note: A collection of links to many of these discoveries can be found in this post in the nominations thread.) ![]() Oscar Cunningham, Dave Greene, and Matthias Merzenich helped to organize the nominations, and b3s23love volunteered to see the project through to completion. In the 2022 competition, users were able to vote on as many patterns as they wish, awarding up to five stars to each one. Self-synthesizing glide-reflecting loopship ![]() Unsynthesizable and limited-ancestor objects There are only two hard and fast rules: patterns must have been discovered in the year in question and patterns must work in B3/S23 ( Conway's Game of Life). Users are invited to submit interesting and noteworthy patterns, their own or others' following discussion, a final list is then curated, and a public vote held. The Pattern of the Year ( POTY) competition is held each year on the forums.
