Search Program Review: LLSSS

This program is good, but it is very intensive on even medium-end computers. While attempting to find a 2c/5d in B256/S4568 in w19 with LLSSS my computer managed to restart itself due to the power consumption (It might just be my computer, though). It didn't even save the command, and I forgot to add "| tee log.txt" anyways. The "--pre-reify-autochoke" argument was even set to 8 GB (out of 32GB ram + 512GB swap). LLSSS doesn't mess around.

9.5/10 - 2026-8-8

This is very versatile, takes low resources (even runnable on my old iPhone 7) and the fact you can use it online is simply amazing. The fact that it can search in Generations rules is nice but not required for your everyday rule. Its only downside is that it can be slow (about 1.5-2 times) then ikpx2 at finding spaceships. And it's not even in the same order of magnitude with the *find programs. It makes up for with its low RAM usage (A classic example of space-time tradeoff). It ability at finding oscillators p<=10 is unmatched except for apgsearch in some cases. It can also act like a more user friendly version of JLS for finding sparkers. And it is also very good at emulating patterns in a BB when paired with a apgsearch stdin symmetry.

9.5/10 overall, -0.5 because its not always the best at spaceship searches, but is a well balanced choice for all occuations.
