In his Lifeline newsletter #3 & #4, M. Wainwright introduced two measures for methuselahs, F.I.P. ratio (final to initial population) and EF, ratio of age to initial pop (evolutionary factor). Do they seem fit to draw correct comparisons ?
Checking their FIP and EF today, I'm not sure our records are so big records.
I found two things to better that :
*Bounding box = 20*20, Nathaniel's ConwayLife soup
Choose a meth and let the initial pattern evolve step by step (I use Golly). There might be a relative minimum in the 100 first steps : restart there, substract the generations, the life span is not too much impacted, e.g. in terms of FIP/EF :
- ErikDeNeve's Long-lived "28987" - 10/10/2009 - goes from 23/200 to 41/200 at gen. 53 (81 new initial cells, started at 145)
- Nathaniel's Long-lived "28158" - 10/2/2009 - goes from 15/196 to 91/1172 at gen. 32 (24 new initial cells, started at 144)
*Any reduced size (n < 20) random pattern
Use the envelope.py Golly script, drawing the maximum extent of the cells, then restart after adding one (still random) block on the envelope edge. No outstanding results, but I suspect some records of their own might appear.
Measure for measure (of soups)
Re: Measure for measure (of soups)
Those measures are good, but it appears that they do not account for bounding box size.
