1 Glider per Bit Oscillator Syntheses

Post by 400spartans » September 23rd, 2020, 6:01 pm

Since the 17-glider RCT shows that every synthesizable SL can be done so at a cost of less than 1 glider per bit, it would be great if the same could be said for oscillators.

There are three main classes of oscillators that would need optimizations:

First are oscillators with a synthesis cost of above 1 glider per bit:

xp2_y2g0k053zw80a02z321 (16G, 15B)
xp2_3lg42mzx10246 (16G, 16B)
xp2_350k0l51z0642 (18G, RCT: 17G, 16B)
xp2_350k04gj4zx642 (18G, RCT: 17G, 16B)
xp2_kg34azwa4o15 (15G, 16B)
xp2_31agozy131ago (14G, 16B)
xp2_4k4g4gljz32 (14G, 16B)
xp2_4k1u1kiczx1 (11G, 16B)
xp2_4l1148kgzx302 (30G, RCT: 17G, 14B)
xp2_k3g4gljz11 (35G, RCT: 17G, 15B)
xp2_8a2543gkz010602 (58G, RCT: 17G, 16B)

As per Mark Niemec, all oscillators with 16 or fewer bits have syntheses, so this would achieve 1 glider per bit for all oscillators with 16 or fewer bits and for all oscillators with 17 or more bits that have syntheses.

To get strictly below 1 glider per bit, the following oscillators would also have to be optimized, as they have a cost of exactly 1 glider per bit:

xp2_xg8o64213zca02 (16G, 16B)
xp2_8ehjzw1050ko (13G, 16B)
xp2_31agozw8k871 (10G, 16B)
xp2_0g4j04g53z32x3 (16G, 16B)
xp2_0g0kc32qkz32 (16G, 16B)
xp2_062k0l51zca02 (15G, 16B)
xp2_y2og853zg0k053z11 (17G, 17B)
xp2_wg0kc321e8z642 (17G, 17B)
xp2_31agozx6a952 (10G, 17B)
xp2_0k3g44gljz32 (17G, 17B)
xp2_y580a13zxg0k0501zca02 (18G, RCT: 17G, 17B)
xp2_y2oga13zg80a13z11 (18G, RCT: 17G, 17B)
xp2_mk461acz1046 (18G, RCT: 17G, 17B)
xp2_c9b88ge2zw32 (18G, RCT: 17G, 17B)
xp2_wj9q453z642 (18G, RCT: 17G, 17B)
xp2_wg0kc32ak8z642 (16G, 17B)
xp2_g84q9jz11x246 (19G, RCT: 17G, 17B)
xp2_31a08gzxo9he2 (16G, 17B)
xp2_31a08zwc850lkg (19G, RCT: 17G, 17B)
xp2_0o080a13zol0407 (20G, RCT: 17G, 17B)
xp2_3lg42mzx1020ac (20G, RCT: 17G, 17B)
xp2_350k0l51zca02 (22G, RCT: 17G, 17B)
xp2_350k04gj4zwca02 (22G, RCT: 17G, 17B)
xp2_0gk0l3gz222x20ac (22G, RCT: 17G, 17B)
xp2_35g40kczx3020ac (22G, RCT: 17G, 17B)
xp2_04k4g4gljz642 (18G, RCT: 17G, 17B)

Optimizing the above two lists would achieve strictly less than 1 glider per bit for all oscillators with 16 or fewer bits and for all oscillators with 17 or more bits that have syntheses.


Finally, while the 17-glider RCT does mean that all synthesized 17-bit oscillators can be synthesized with 17 gliders, this doesn't fully show 17 in 17 for oscillators, as there are 14 17-bit oscillators that have yet to receive any syntheses (from Mark Niemec's list above):

xp2_3lg42mz2c0203
xp2_j92g55hz11x3
xp2_j92g5jz11x23
xp2_k51h4gljzw3
xp2_0m24gl3z2a882
xp2_35g41h54gzx3x3
xp2_31a0nzwc850e
xp2_m24g441lpz03
xp2_3hk2060szw2251
xp2_35g411l4z22403
xp2_0b1205jgz1140c02
xp2_31a0nzw4490ac
xp2_62k030288zx1148d
xp2_62k030288zx3048d

Let me know if there's anything missing from the above lists.

First of all, I'd like to mention that there may be a 3-GPSE RCT-based universal constructor coming soon.

About the oscillators in the first category, there seem to be patterns. All but one of the oscillators has a larger rotor than stator, all but two of the oscillators have a rotor at least twice as large as its stator, and six out of the first seven have at least one part that resembles the end of a barberpole. It may be that oscillators with higher volatility are simply harder to construct, possibly because they're more "random". However, I'm surprised that number six (the bipole-tie) is so expensive, given that a ship-tie is probably fairly cheap and there's an easy way to turn a ship in a tie into a bipole with a century, which only costs three gliders.

Edit: It turns out that I was thinking of a quadpole, not a bipole, but the four-glider method for turning an aircraft carrier in a tie into a bipole on the Catalogue page appears to work for the second aircraft carrier for either relative timing (although the other relative timing already has a nine-glider synthesis on Catalogue), which I think means a 14-glider synthesis total.
I am tentatively considering myself back.

Here's another 14 Glider construction for [16P2.58] using an intermediate 12-bit stable object [12.76]--

(I double checked this time, to make sure it works, just to be sure.)

Half of the second step can be delayed one generation to change the phase of part of the oscillator to make [16P2.59], although that object can be constructed by just 9 Gliders.

xp2_31agozx6a952 in 15G...
Hang on a moment, there's a whole section at the lower left with the block and blinker, that ends up contributing nothing but a two-bit spark. Replace that with a two-glider spark source and the whole thing can be done in 10G or possibly a little less:

Code: Select all

x = 100, y = 140, rule = LifeHistory

Re: 1 Glider per Bit Oscillator Syntheses

Muttering moat 1 was reduced by a glider, so xp2_3lg42mzx10246 is reduced to exactly one glider per bit:

Code: Select all

x = 164, y = 35, rule = B3/S23

xp2_31agozw8k871 in 12G, there's probably a more efficient cleanup (those last 2 gliders in the middle reaction are technically cleanup).

Code: Select all

x = 169, y = 78, rule = B3/S23

I think that this reduces the cleanup from three gliders to two, but a one-glider cleanup seems plausible.

Code: Select all

x = 30, y = 22, rule = B3/S23

I am tentatively considering myself back.

Yup, even Seeds of Destruction can turn something up in a few minutes:

Didn't someone publish a Hit-Active-Reaction-With-All-Possible-Single-Gliders script at some point? Maybe modifiable to require the continued existence of the target object? That's a search that shouldn't take very long, and if a script were well advertised it would save a lot of this painful reduction in cleanup cost, in cases where it should really be possible to jump to the 1G cleanup immediately.

xp2_8ehjzw1050ko in 13G (cleanup likely improvable), which should also knock xp2_wg0kc32ak8z642 and xp2_31a08gzxo9he2 off the list:

Well, there's this, but it's going to need some nontrivial modification to find one-glider cleanups.
