Yes, the blinkers that are already there form the instruction tape. It's translated by 2 cells to the right by this reaction (which will be the velocity of the spaceship). You can't move your blinkers and burn them too. The blinkers in the (very very long) tape are different from the blinkers in th...

### Re: How about a unidimensional spaceship?

It looks like forward HWSS-creating reaction might be sufficient for initial construction. The reaction can be used to create an arbitrary stream of single-channel monoparity HWSSes. The stream can then be aimed at a blinker elbow (or elbows) to (hopefully) provide universal construction. Here is a...

I don't think that's likely to work, because oscar.py/oscar.lua relies on the idea of keeping track of a list of just the lowest hash values in a range of tested generations. For a period-P pattern I don't see how you can be sure that you're going to find the matching hash value until you've tested...

Could we speed up oscar.py by only looking at generations from a sparse ruler , and using hash life to jump between them? Yes, that's exactly what lifelib does. The pdetect algorithm in lifelib accepts an upper limit N as a parameter, and it constructs a finite sparse ruler of size O(sqrt(N) log(N)...

The problem is with the Catagolue update process, rather than Shinjuku, and it's difficult to resolve without making deep changes to the way Catagolue stores glider syntheses. Specifically, there's a census called b3s23/synthesis-costs which records the cost (in gliders) of every object Catagolue kn...
