Re: Spaceship Discussion Thread

Wait a minute, why isn't Minstrel 18 named Minstrel 16 if there is no Minstrel 16 and 17? The "History" and "Minstrel arithmetic" sections of the Sir_Robin#Tagalongs LifeWiki article can tell you more. Long story short, it seemed like a good idea at the time... at least to calcyman, who was after a...

Re: Spaceship Discussion Thread

There appear to be new minstrels in ikpx2_stdin. I did not find these. Before anybody gets their hopes up too much, these are just M7, M18, and M11 in the current stamp collection . The mysterious missing Minstral #16 and Minstrel #17 will have to wait for some more auspicious time to show themselv...

Re: LifeSuper rule

As for use cases involving all cell states, we could for example use it to annotate a theoretical period-19 gun or something which can only be constructed using special cells. Sure, but that honestly needs only one label cell state. It definitely seems like a reasonable idea to tack [R]Extended ont...

Here is file RuleTreeGen.java... Just replace the Life definition in int f(int[] a) with an MNCA rule definition, compile and run.

Re: Oscillator Discussion Thread

If we follow the usual guidelines, the discoverer gets to name the discovery. Makes sense, but what about the object being hassled? Good point. I won't venture an opinion about that. My approach would be "wait a year and see if anyone ever mentions it again after that, and then see what they call i...

Re: Oscillator Discussion Thread

I think we should probably decide on an official name for the object first. "U-turner" always makes me think of something turning a "U". If we follow the usual guidelines, the discoverer gets to name the discovery. That happened a while ago, and the name is Raucci's p217 . Not sure everybody notice...

dvgrn, should I continue updating the oscillator page or not? You said you were changing the comments, and if I update it, we would have two separate versions that would be hard to merge.

Can't say I've found any new bugs with LifeViewer ruletable loading that can be traced to this so far. There does seem to be a formatting error that arises in the box for certain rulestrings though, which seemingly also breaks the link: https://www.conwaylife.com/wiki/Rule:TriVN-B123x2_S1_emulated ...

Re: Who proved the universality of the GoL ?

It also seems that we have to draw a clear line between two properties :a) the Turing-universality of the model, that is, the ability to compute any algorithm, and b) the self-replication ability (including the self-replication of a Turing machine). I have to read again the arguments exposed above ...
