Execution of Old Guns by Variable-Speed Firing Squad

[Sokwe]

I saved an additional 3 columns in the p57 by reducing the non-compound domino sparker using LLS. I also confirmed with LLS that any shorter solutions (if they exist) would make the overall gun taller. I was not able to reduce the bounding box of the compound p3, but I changed its shape a little to give more room near the output stream:

This latter modification was enough to pull the tremi-Snark in by one diagonal in the p171 gun:

Edit (Feb. 7): I'm still messing around with my little JLS-to-LLS script. Here is a 3-column reduction to the p28 gun found with LLS:

Code: Select all

It might be possible to remove more columns on the left side, but I'm doubtful. On the right side any p4 reduction in columns would make the gun taller.

Edit 2 (Feb. 7): Here's a very slight reduction to the p552 gun (one row shorter, but also one column wider):

There may be smaller solutions. I know at least that by only replacing the p4 with another p4, a height-19 solution is impossible, a height-21 solution would require a width greater than 50, and a height-22 solution would require a width greater than 45, so there are no solutions in a 1000-cell bounding box.

Here's a minor reduction to gun_14 from 110x84 (9240-cell BB) to 108x83 (8964-cell BB) by implementing the reduced p4 sparker as found in the new p28 gun engine (And with bonus reduction potential from the JLS to LLS tool as well!)

I've been using my JLS-to-LLS script to attempt to reduce some overly large low-period supporting oscillators.

Ooh, I suggest trying to reduce the extremely big P5 oscillator in the P35 gun. Unless you did that already.

This was mostly a test to see if I could do anything. It's obvious that there are smaller solutions.

In this case, I used LLS to find a rotor split, and I then completed the branches with JLS. This worked reasonably well, as think JLS would have done very poorly trying to find the split, but LLS found it quickly. However, being able to see the partials in JLS made it better for completing the branches. I tried to find a shorter branch completion with LLS for that rightmost-extending branch, but my setups kept taking too long only to come back unsatisfiable with nothing to show for it. I think I need more practice setting up LLS searches to get a better sense of what works. The above form at least provides a bounding box limit for any further LLS searches.

I'm also searching for an alternate solution with a different p35 interaction, but I've had no luck so far.

Here is the previous form of the p35 gun for comparison:

I’m curious about who submitted that.

Edit (Feb. 7): I'm still messing around with my little JLS-to-LLS script. Here is a 3-column reduction to the p28 gun found with LLS:

Code: Select all

It might be possible to remove more columns on the left side, but I'm doubtful. On the right side any p4 reduction in columns would make the gun taller.

Smaller p56 gun as a result (BB 31x29, down from 34x29)

Code: Select all

x = 31, y = 29, rule = B3/S23

Bringing back the lowermost wing from the 104x65 true-period p35 gun should allow for up to 8 more columns to be shaved off rather than the zero columns that your 84x65 p35 gun design actually allows for:

For some reason I thought it didn't fit, but I guess it does. A quick JLS search reduces it by one column, but further reductions will likely require more significant changes to multiple branches:

[...] I think you can DIY that by submitting the canonical form through the nonmagical box in https://catagolue.hatsya.com/syntheses

[...]
The goal of this collection is to include the smallest glider gun for each period. Size is measured by the area of the bounding rectangle of the gun. Every cell that is a part of the rotor or stator of the gun must be included in the bounding rectangle, excluding only the output gliders. [...]

[...]

If you send a large number of guns, it would be helpful if they are in the "canonical form" for this collection, which means:
1) The gliders travel to the lower right.
2) The pattern is in the last phase before a glider leaves the bounding box.
3) The width is greater than or equal to the height.
4) The initial pattern should recur exactly, except for the output gliders (and optional extra cells to mark the bounding box). Do not delete any extraneous sparks, etc.
