Simply checking whether a pattern matches a previous generation would keep delivering false negatives if the final pattern has two spaceships with different velocities or both a spaceship and a still-life or oscillator.

Re: Thread for basic questions

Is the glider synthesizability of any given pattern computable? Technically, by the classic definition of " computable function ", an algorithm is allowed to run forever if no such glider synthesis exists. So I think glider synthesizability _is_ computable -- there's a program that will return a gl...

It should be possible (although very expensive), but why would you want to? Converting a block into a table can already be done with 5 gliders: 3 gliders turn block into boat, and 2 gliders turn boat into table.

That might be useful as a synthesis component.
There are much cheaper ways to turn a boat into an eater. That can be done with a mere four gliders, and when the boat is in that position, a side-effect would be the additional connecting bit.

Re: Thread for basic questions

Many glider syntheses, especially those from random collision enumeration, start from a 2-glider collision; and other gliders join in the reaction some (say, 4)or more generations later.
