Revision as of 21:49, 5 April 2019
- Apr. 5: An exhaustive computer search run by Nathaniel Johnston reveals that there are 14,223,867,298 strict and 15,851,861,075 pseudo 33-bit still lifes, including eleven pseudo still lifes that can be partitioned into three stable pieces but not two, and none that can be partitioned into four stable pieces but not two or three.[1]
- Mar. 27: The last remaining 14-bit still life, xs14_4ai3zwo9a4, appears in a C1 soup on Catagolue, in a haul submitted by an anonymous user.[2]
- Mar. 24: apgsearch v5.03 gains the ability to log 'megasized' soups with final populations exceeding 3,000.[3] apgsearch 5.x can also pre-process asymmetric C1 B3/S23 soups on GPUs with CUDA support.[4]
- Mar. 7: A spider synthesis using 574 gliders and 9 LWSSes is found by Martin Grant. [5]
- Mar. 3: A period-120 oscillator, the highest period thus far, occurs from a natural soup on Catagolue.
- Mar. 2: Several symmetric-soup diehards with lifespans over 1500 ticks have been found by 'carybe', using apgsearch..
- Feb. 12: A lightweight Schick engine appears from a natural (C1) soup on Catagolue.
- Feb. 9: A 47,575-tick 16x16 methuselah found by Adam Goucher via apgsearch yields a 16-cell, 47,487-tick methuselah. This discovery skips over several empty 1000-tick bins in Catagolue above the previous record 16x16 methuselah, Homer.
- Feb. 4: A glider detection and removal upgrade in apgsearch version 4.91 gives a search speed boost of well over 50% compared to version 4.88.
- Feb. 4: Tanner Jacobi and Martin Grant find a recipe, subsequently reduced to 88 gliders, for the first-ever synthesizable c/4 spaceship, 46P4H1V0.
