Also, is it just me, or is Catagolue not updating with these syntheses?

I reduced the cost to 46 by making the block+R region near the beginning with three gliders instead of four and making a partiall delayed domino spark with three gliders instead of four.

It's currently at 47 gliders, but I strongly suspect that the tub-with-tail-bridge-loaf motif could be replaced with something that's cheaper to add. Any improvement would at least make this method tied for most efficient, and cheapening it by at least two gliders would yield an outright lower cost than anything we have so far.
For reference, my first version of this method cost 54 gliders, so the fact that I have already been able to reduce the cost by seven gliders so far with my rudimentary component knowledge demonstrates that maximum efficiency is not guaranteed and thereby suggests that further improvement is possible.

Thank you for informing me. If I copy and paste my syntheses into the bottom of the box at https://catagolue.hatsya.com/syntheses, is that enough to ensure that they will be added to Catagolue once the relevant issue is fixed, or is there some repository-thread where I should put them in order to prevent them from being forgotten? (I suspect from the fact that staging has been running okay that the answer is the former, but I figure that I should check.)



Edit: I improved the cleanup for the synthesis of xs19_642tik8z2552 (the first part of the synthesis of xs30_3ihf8b5zj2s513z11) by one glider.

I found it by running glider-destruction.py (from this forum post) on the following RLE, where I added some additional still-lives to destroy the desired still-life and a beehive and blinker that I viewed as too distant to attempt to clean up along with everything else in order to prevent the program from also worrying about cleaning those things up.

Code: Select all

x = 25, y = 35, rule = B3/S23

I figure that I would mention this because there have been numerous occasions when I have used this workaround in order to effectively tell glider-destruction.py to only destroy certain parts of a pattern.
I am tentatively considering myself back.

It's currently at 47 gliders, but I strongly suspect that the tub-with-tail-bridge-loaf motif could be replaced with something that's cheaper to add. Any improvement would at least make this method tied for most efficient, and cheapening it by at least two gliders would yield an outright lower cost than anything we have so far.
Actually, it turns out that the tub-with-tail-bridge-loaf motif can be added with six gliders instead of eight (maybe even fewer), so this is now the most efficient way to synthesize xs30_3ihf8b5zj2s513z11. Specifically, combined with KtT's and my cleanup improvements, the cost is now 43 gliders.

By the way, here is a related method that uses a tub-with-tail-bridge-beehive motif instead of a tub-with-tail-bridge-loaf motif. It's currently two gliders worse than the version that I just posted, but I'm posting it here in case someone either can improve it or wants to make a tub-with-tail-bridge-beehive motif in the future.

Edit: Mark Niemiec's database has a way to make the necessary blinker predecessor cleanly with three gliders, thus yielding a further one-glider improvement in the cost of adding the tub-with-tail-bridge-loaf motif. This reduces the total cost of xs30_3ihf8b5zj2s513z11 to 42 gliders.

Another edit: It turns out that the initially-posted method used a three-glider domino spark in the creation of the canoe motif when a two-glider dot spark would have sufficed.

In light of the improvements to the cleanup of xs19_642tik8z2552, this reduces the cost of that method from 44 gliders to 43 gliders, which is still one behind with respect to the lead.
I am tentatively considering myself back.

A simple clean predecessor of xs36_4aab8ba96z255d1d596 (object at bottom is a B-predecessor perturbed by a dot spark)

Code: Select all

x = 8, y = 27, rule = B3/S23

Currently working to improve Life's guns and work on updating SKOPs and Isotropic rules most similar to B3/S23 to Life standards. Will get software to begin searches eventually.
