Re: Oscillator Discussion Thread

AGreason & WildMyron's agar A note on attribution - I found the p6 and p8 agars (via SAT solver), and noted both the p6 and this one (the p8 moreso) give the impression of a background with vertically-propagating disturbances, which may be suggestive of a way to make arbitrary even-period phoenix a...

Re: Oscillator Discussion Thread

Collecting some phoenix agars (so I have something to cite for lifewiki) (note: the following are finite portions, large enough that it's clear it can be tiled indefinitely) p2: x = 30, y = 21, rule = B3/S23 2o2b2o2b2o2b2o2b2o2b2o2b2o2b2o$2o2b2o2b2o2b2o2b2o2b2o2b2o2b2o$2o2b2o2b 2o2b2o2b2o2b2o2b2o2b2...

EDIT: depth 3 complete, 757 unsynthed

Re: Soup-based syntheses

If they are neither soups nor syntheses, why post them in the "soup-based syntheses" thread?

Re: Oscillator Discussion Thread

I have verified via SAT solver (using apgoucher's GRILLS to set up the SAT instance) that there is no 11 cell by 11 cell by 5 generation patch, with the outer rim set freely and the interior constrained to follow cgol rules, that satisfies the following criteria: A. is a p5 oscillator B. is a phoeni...

Re: Synthesis component search script

I ported the main loop of my version to C++, for a significant speedup, and put it on github https://github.com/AlexGreason/Collisearch . Note that you'll have to manually set the lifelib path in CMakeLists.txt to wherever your lifelib installation is This version gets almost 50k collisions/sec (2-g...

Re: 17 in 17: Efficient 17-bit synthesis project

please can you accept merge request 38, containing Alex Greason's collisrc+transfer results? There are plenty of new efficient xs17 syntheses in there, so it might get us significantly further through the project To moderate expectations, if I recall correctly only two expensive xs17 were reduced b...

Re: Synthesis component search script

I made some modifications to the script. 1. I removed the requirement that at least one cell of the initial target remain alive throughout the reaction 2. it can now search in parallel, set the --n-threads argument for the number of search threads 3. instead of running collisions with a single objec...

Re: Soup search results

My first first discovery (first appearance in C1, anyway, it's shown up a number of times in other symmetries): https://catagolue.appspot.com/object/xs34_025b8b52z0g6t1t6gz121x121/b3s23 , a nicely symmetrical 34-bit still life, which came from this: https://catagolue.appspot.com/hashsoup/C1/l_nyYtRC...
