Execution of Old Guns by Variable-Speed Firing Squad

Minor reduction to gun_140 (1376 -> 1333 EDIT: actually 1290) by using a p20 to filter a p70:

x = 43, y = 30, rule = B3/S23

The p20 filter is 20 rows deep, so it should only be used if something else doesn't work.

Should I stop posting these?
Well there are no hard-and-fast restrictions on what is "the highest period to post". On the other hand, there are too many improvements to be made, before every gun from p1000 through p9999 reaches some limit beyond which reductions would become impossible or impractical. It might be better to reserve this forum thread for periods below 2000 or so.

Note that there are several other gun-related threads, including a forum thread Small Four-Digit Prime Period Guns (guns with prime number periods from 1009 to 9973).

Thank you, I will do that.

gun_35 reduction (4399 -> 3570) by using the smaller p70 gun:

Probably more room for reduction.

This might help slightly reduce a few guns.

The left one and the width-optimized variant have bounding boxes of 15x11=165 and 14x13=182 respectively, while the right one has a bounding box of 14x12=168. I also overlaid them to show it better:

sorry for doublepost, but this really deserved another post.
Surprised how with the new gun_70, no one attempted to reduce gun_35, so I did just that:

p486 gun reduced from 49x42 (2058-cell BB) to 51x38 (1938-cell BB), achieved by overclocking a Hexa-Snark (a slight modification to the Quinti-Snark by allowing a spare beehive to be cleaned up by an additional glider instead of a fishhook) into a dependent "Ennea-Snark":

(Haven't read all 40 pages, sorry)

Did anyone tried to make tool-assisted improvements to guns collection?
I was surprised to discover that lots of room for improvements exists even at basic levels.

For example, I made program which lists possible optimizations from applying x2 multiplication with Blocker:

Code: Select all

using System;
using System.Collections.Generic;
using System.Net;

namespace ConsoleApplication142
{
    class Program
    {
        static void Main(string[] args)
        {
            System.Threading.Thread.CurrentThread.CurrentCulture =
                System.Globalization.CultureInfo.InvariantCulture;

            var list = new WebClient().DownloadString(
                "https://catagolue.hatsya.com/textcensus/b3s23/synthesis-costs/gun");
            var lines = list.Split('\n');

            var guns = new Dictionary<int, int>();

            for (int i = 1; i < lines.Length - 1; i++)
            {
                var spl = lines[i].Split(',');
                int period = int.Parse(spl[0].Trim('"').Substring(4));
                int area = int.Parse(spl[1].Trim('"'));
                guns.Add(period, area);
            }

            for (int i = 14; i < 10000; i++)
            {
                if (!guns.ContainsKey(i))
                    continue;

                if (i % 4 == 0 && i % 8 != 0)
                {
                    int j = i * 2;
                    if (!guns.ContainsKey(j))
                        continue;
                    string g1 = "gun_" + i;
                    string g2 = "gun_" + j;
                    int a1 = guns[i];
                    int a2 = guns[j];
                    Console.Write($"{g1,8} -> {g2,8}: ");
                    double ratio = 1.0 * a2 / a1;
                    if (ratio < 1.0)
                        Console.ForegroundColor = ConsoleColor.Red;
                    if (ratio > 1.0)
                        Console.ForegroundColor = ratio > 1.5 ? ConsoleColor.Green : ConsoleColor.Yellow;
                    Console.WriteLine($"{a1,5} -> {a2,5}  {ratio:0.00}");
                    Console.ResetColor();
                }
            }
        }
    }
}

I already optimized gun_1064 and gun_1080, but more improvements from this list are possible.
With simple modification to this program, possibilities for applying p16, p32 and other filters can be listed as well.
Other improvements can include for example utilization of information about bounding boxes.

Did anyone tried to make tool-assisted improvements to guns collection?
[...]

Short incomplete answer: yes.
Not counting the current Catagolue's submission form and the gun/guntrue collection, there are these links:

viewtopic.php?f=9&t=5643 "gloc.py - for glider guns we may have missed"
viewtopic.php?p=174297#p174297
A forum search over this thread

I wonder what would be consequences to the gun collection if all recent discoveries are accounted for (fixed-coefficient pulse dividers, extensible pulse dividers, conduits/catalysts, ...).

Reading the question literally, Golly is a software tool, and people used Golly a lot for various improvements to guns collections.

Thanks.

I was thinking about expanding current database as well (by filling it all up to 9999), but then discarded this idea, because someone will have to maintain all of this -> if base gun is improved, all variations will need improvements as well.

Chains of filters can be merged into snarks, right.
With hint from my program it allowed for example to reduce size for gun_1376 from 9936 to 2420, so changes can be massive.
