Re: Soup-search based PoW mechanism ( using of messless)

Difficulty table works like planed economy, it would be better let the market decide price of each type of object. when profit is enough, miners would not waste any potential interesting soups. The difficulty table is not a (prescriptive) table of prices ; it's a (descriptive) table of the reciproc...

Re: Soup-search based PoW mechanism ( using of messless)

Using messless as a proof-of-work would have the problem that people would discard a soup as soon as it has an escaping glider, and therefore miss lots of discoveries that would have been found by running those soups to completion. So, even if we had a multi-billion-dollar cryptocurrency, we'd be un...

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).

Uh, this is cool and all, but how do you plan to put back the blinkers? There needs to be a copy of the instruction tape somewhere.

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.
