I've found a number of forerakes on track pairs, but none of them are clean. This unlikely pair is the cleanest so far, a forerake with only two pieces of debris. The same pair provides 4 dirty rephasing reactions by stalling the left climber 36, 44, 56 or 64 generations. 5 unique options is good, b...

Very weird! Looking at the population, I imagine the "agar" is a glitch in displaying the pattern and not in generating it, possibly some bug to do with grid display. It's 8,8 periodic in the plane, and has a weird nontrivial interaction with the underlying pattern. Strangely, at the top left just t...

The script has the expected behavior on my computer with Golly 2.8, Python 2.7.12 and Windows 64bit. Perhaps the beta version of Golly 2.8 is the problem? Or some external corrupted file?

All apgsearch is doing is many independent iterations of the same task - evolve random soup and census objects. The operative word there is "independent," which differentiates it from the sorting algorithm you mentioned. Soups need to share no information. As such, there is no way to have a better a...

The description by biggiemac mentions that support for C2_2 needs to be added, but it looks like that has already been done . I don't remember that any likely options are missing from the list of supported symmetries (?) All options are present and have been since symmetric apgsearch began. I was r...

That's a nice construction! I think that would cost around 150 *WSS to fanout from a single stream, making this helix about twice as complicated as that of the original caterpillar. I'm hoping to avoid breaking the "largest interesting construction" record, I don't know if I'm alone in this. I would...

Look at the new still life created in gen 36. This can be useful in syntheses. x = 23, y = 14, rule = B3/S23 4bo$2obobo$bobob3o$bobo4bo$2b2ob4o$5bo$5bob4o$6b2o2bo3$20bo$20b2o$21b 2o$22bo!

The issue with the caterpillar isn't that things have to be a multiple of 4. The waterbear uses *WSS for a p158 helix, which last I checked is 2*79. Successive spaceships in the helix are just in different phases, like this. x = 37, y = 71, rule = B3/S23 4b3o$6bo$5bo2$16b3o$15bo2bo$18bo$18bo$15bobo3...

Perhaps a more appealing presentation of muzik's discovery - it requires only two gliders on the same lane to produce an eater eating all later gliders on that lane. 16 is far too close for any construction toolkit, but I have seen applications including the linear propagator, in which an eater was ...

Just checked out your attachment - that's good news, especially if it turns out the climber pair is capable of building up the other 3 to make a full cluster. That puts the total number of spaceships to synthesize at 23 on the right, and 20 plus the helix on the left. The helix would have to be adap...

What I meant when posting the linked comment: Pages can be generated by just placing the apgcode in the appropriate place in the URL. But there's no reason for those pages to actually go into the network graph until there is some other data to store about it external to what can be autogenerated - s...

That's a good start! The picture I had in mind involved some frozen tracks. An early duplicator split off the NE-traveling signal into NE and SE. The NE just travels a large distance as a delay mechanism, while the SE glider is repeatedly duplicated as in the original caterpillar to build a constell...

Following up on the above, climber pair 2 has a bit of construction capability all on its own. There are two other reactions that don't destroy the track and that leave debris, plus a third if you allow rake input. The spark can interact with the debris to get a very messy forerake. This gives us a ...

I updated the script to allow for a defined number of NE and SE gliders. Also I added some more starting configurations. Good news is that the loaf + block can be made in two NE gliders like so: RLE but I don't know how to make that starting configuration so I can't tell how expensive it will be. A...

I'd say we are about 30% of the way through the planning phase. We still have to figure out the right-side helix to get a cluster started. The helix we have right now will merely feed x3 gliders to the front right corner of the ship, it's the task of a bunch of other *WSS to turn them into the first...

I said 670, I was mistaken. The post on the earlier page was about 1670 vertical cells to a frozen track. Using a pi + blinker reaction found in the results file, I improved it to just under 1000. This has more debris hidden behind the trail, but I believe some of the rephasers can be turned into ra...

(Remember when bwbigmac had 80+% of the pie chart?) Back when the college I was in didn't care that I monopolized their lab's down time.. Too bad apgnano/mera weren't available then. I was only running the golly python script, meaning I was about an order of magnitude less efficient, at least in ti...

Thanks for running the script! I think there should be some effort put into looking for slow pairs, since we have the option. The 3C3 block + loaf posted earlier was one of those constellations plus only 6 slow signals, one of which was a pair, and is the current record at I think 670 vertical cells...

Here are all the cheap target constellations for 2C3, 3C3 and 4C3. x = 1419, y = 293, rule = LifeHistory 140.F90.F88.F71.F89.F89.F89.F89.F27.2A60.F89.F27.2A60.F89.F89.F71.F 71.F71.F$140.F90.F88.F71.F89.F89.F89.F89.F26.A2.A59.F89.F27.2A60.F89.

Assuming we using a cluster with a backrake in the bi-block position, the following are always permitted, with the glider parity and color dictating those of salvos in both directions. x = 83, y = 18, rule = B3/S23 bo19bo19bo19bo19bo$2bo19bo19bo19bo19bo$3o17b3o17b3o17b3o17b3o4$4b3o13b 3o13b3o$6bo15b...

The LWSS inserter works, even for the tricky spot where the Caterpillar synthesis didn't and I had to resort to the one from the Waterbear. Good find! x = 201, y = 477, rule = B3/S23 193bo$193bobo$193b2o43$174bo$174bobo$174b2o43$155bo$155bobo$155b2o43$ 136bo$136bobo$136b2o16$27b3o2$25bo$25bo4b2o$25b...

The nice thing about the MWSS-based tripler is that the two trigger gliders can be sent as-is by the backrakes and forerakes. With the lane and phase restrictions, that's pretty good luck on our part. I also found a much cleaner way to triple the period by placing a loaf next to the blinker. Shown i...

Little collision takes impressively long (~200 gens) to stabilize into a clean pi heptomino. Doesn't travel particularly far.

Additionally, try using code tags instead of attaching images. That makes it work well with the built in life viewer if we want to run it ourselves, and doesn't take up an oversized box that force resizes the forum page. These forums aren't the greatest for image sharing.

Here's a rather clean cheap period tripler based on an MWSS. I am still looking to see if there is one with less debris. x = 120, y = 281, rule = B3/S23 obo$b2o$bo43$17bobo$18b2o$18bo43$34bobo$35b2o$35bo19$118b2o$118b2o$ 111bo$111bo$111bo20$51bobo$52b2o$52bo$117b2o$117b2o$110bo$110bo$110bo 23$116b2o...
