Slowest spaceship in a MAP rule.
Posted: May 27th, 2020, 4:00 pm
I know this is similar to the "slowest 1-cell spaceship" topic, but I am just curious about what the slowest one is.

Yes, the top-right cell would cause another birth further in the directionPkmnQ wrote: May 28th, 2020, 3:38 am Is there anything wrong with:Code: Select all

Doesn't matter though because the existence of arbitrarily slow spaceships necessarily means there is no slowest spaceship across map rules.LuxiusGOL wrote: May 27th, 2020, 5:53 pm There are 13,407,807,929,942,597,099,574,024,998,205,846,127,479,365,820,592,393,377,723,561,443,721,764,030,073,546,976,801,874,298,166,903,427,690,031,858,186,486,050,853,753,882,811,946,569,946,433,649,006,084,096 MAP rules. That number is huge compared to the 262,144 regular rules
That's still quite easy, take an adjustable ship rule, say this (src: viewtopic.php?f=11&t=3081#p54706):Hunting wrote: May 29th, 2020, 11:58 pm What's the slowest one in a non-isotropic 2-state rule, though? CGoL is isotropic.

or cells of spaceships that are lower than the boundary box for spaceships in a B/S rule?Hunting wrote: May 30th, 2020, 12:09 amOh, you win.
