Re: A new spaceship search approach

Post by May13 » February 6th, 2022, 2:34 am

I found a more serious bug.
LSSS fails after 0012/done with "No spaceship found for seedcolumn 02" for rule B2567/S4568, speed 2c/3, seedcolumn 02, margin 32 and odd-midline.

Code: Select all

#!/bin/bash

lsss=target/release/life_slice_ship_search

# Set data variable to an empty directory with plenty of space for
# storing slices.
# To interrupt the search "echo 0000 > data/stopafter",
# and the script will exit after some time.
# To resume the search "echo 9000 > data/stopafter",
# and run this script. It will resume from where it was stopped.
# Partial results will be saved in the data directory.
# The partials will need to be mirrored.

data=data

margin=32

#midline=--even_midline
midline=--odd_midline
#midline=--gutter
#midline=--zero # use for Asymmetric, add 1 to margin.

parms="--velocity (2,0)c/3 --rule B2567/S4568"

# For an exhaustive search re-run the search with seedcolumn changed to all
# the values from 00 to the margin.
# Note however that if a spaceship is found it will not be possible to
# continue the search for that seed as the disk space will blow up.

seedcolumn=02

declare -a exclude

# The exclude parameter can be used to exclude results that are not wanted.
# This could be useful for excluding repeating patterns or lower-period
# spaceships. It is a manual process.

# Usage:
#
# 1. Find the partial that contains the pattern to exclude.
# 2. Pick a slice (two columns) near the middle of the pattern.
# 3. Trim off excess from the tail of the pattern.
# 4. Pass the two columns to --exclude separated by a /. The "left" column
#    goes first.
#
# Notes:
#
# * Trailing spaces in the exclude pattern are significant.
#
# * The results in the partial files are rotated and sometimes flipped. So the
#   left column (that goes first) is the lower row in the odd-numbered
#   partials and the higher row in the even-numbered partials.
#
# * The amount of information to specify what to exclude is fairly limited
#   (Two columns of the pattern for one phase.) To avoid excluding more
#   patterns you do not intend to do not be aggressive in trimming the
#   tail.

#exclude+=(--exclude)
#exclude+=(" ** * * /**  ***")

I found a more serious bug.
LSSS fails after 0012/done with "No spaceship found for seedcolumn 02" for rule B2567/S4568, speed 2c/3, seedcolumn 02, margin 32 and odd-midline.
Thanks. I've reproduced the problem and am looking into it.

Hi May13,

I've pushed out a fix for the bug. It impacted searches where k+1 == p (1c/2, 2c/3, 3c/4, etc.) and could cause spaceships to be missed. It might also cause inconsistent partials to be printed. It's not impossible to have a spurious "Potential Spaceship found" message even in the absence of the bug, but I suspect that message was related to the bug as well.

Thank you for the report.

LSSS v3.8.0 really works for 2c/3 orthogonal in B2567/S4568. Here's 2 similar very wide 2c/3 spaceships (frontend from LSSS; completed using JLS):

About false "Potential Spaceship": I think that this bug is related to process of extracting a partial spaceship. I have not seen such messages, but this partial looks unusual (from 0149.partial.txt):

While most partials are empty in the middle, this one has an unfinished component that can be seen as finished by the program.
The latest version of hex-gliders.db have 640 gliders from OT hexagonal rules. Let's find more!

I couldn't correct this by pulling from git, and the program completely stopped working after I deleted the LSSS directory and cloned from github.

Please try updating to the latest version of rust.

The command "rustup update" should update the version of the compiler.

It's calling a nonexistent file that is supposed to be in the ./target/release directory, and which is defined in line 3 of the search.sh.

EDIT: A user told me to write

Code: Select all

RUSTFLAGS='-C target-cpu=native' cargo build --release
which took me back to the original problem: LSSS stopped making the frontend correctly.

I was having a similar issue of LSSS just stopping at depth 11 on everything on the newest version. The version where the threads parameter was changed works for me.
I manage the 5S project, which collects all known spaceship speeds in Isotropic Non-totalistic rules. I also wrote EPE, a tool for searching in the INT rulespace.

Things to work on:
- Find (7,1)c/8 and 9c/10 ships in non-B0 INT.
- EPE improvements.

Sure, what version do I checkout?

So, some directory names seems to have been altered. I reverted the changes in search.sh by going back to the 3.7.3 version of that file and this seems to fix the problem for now.

@LaundryPizza03 : Try checking out 3.7.3, but test if the change in workspace.rs needs to be applied for your searches

So, some directory names seems to have been altered. I reverted the changes in search.sh by going back to the 3.7.3 version of that file and this seems to fix the problem for now.

@LaundryPizza03 : Try checking out 3.7.3, but test if the change in workspace.rs needs to be applied for your searches
Done. Seems to be working now.

Re: A new spaceship search approach

I was testing the newest version of LSSS, and in B3/S23 with speed (1,0)c/2, margin 10, gutter symmetry, and seedcolumn 01, it endlessly prints out 70P2H1V0.1 after depth 0027. The subsequent rows are blank. Search parameters that yield no spaceships seem to run normally.

Since december of last year Andrew inplemented support for spaceship detection in the script, although it might not work on some occasions, this i've noticed myself.
If you find a ship at a certain margin, gutter and seed combination, that's about it. The script doesn't skip the seed or exit all together, it just prints out a "possible spaceship" notification and will just continue until you run out of disk space.

But if you don't want to find the same ship, you can exclude patterns for that search combination.

While searching for 2c/3 spaceship in B267/S34, I got message about potential spaceship, but I found no spaceship in file.
I have a similar issue in B2568/S0458. Search configuration:

Code: Select all

#!/bin/bash

lsss=target/release/life_slice_ship_search

# Set data variable to an empty directory with plenty of space for
# storing slices.
# To interrupt the search "echo 0000 > data/stopafter",
# and the script will exit after some time.
# To resume the search "echo 9000 > data/stopafter",
# and run this script. It will resume from where it was stopped.
# Partial results will be saved in the data directory.
# The partials will need to be mirrored.

data=data

margin=17

#midline=--even_midline
midline=--odd_midline
#midline=--gutter
#midline=--zero # use for Asymmetric, add 1 to margin.

parms="--velocity (2,0)c/3 --rule B2568/S0458"

# For an exhaustive search re-run the search with seedcolumn changed to all
# the values from 00 to the margin.
# Note however that if a spaceship is found it will not be possible to
# continue the search for that seed as the disk space will blow up.

seedcolumn=00

declare -a exclude

# The exclude parameter can be used to exclude results that are not wanted.
# This could be useful for excluding repeating patterns or lower-period
# spaceships. It is a manual process.

# Usage:
#
# 1. Find the partial that contains the pattern to exclude.
# 2. Pick a slice (two columns) near the middle of the pattern.
# 3. Trim off excess from the tail of the pattern.
# 4. Pass the two columns to --exclude separated by a /. The "left" column
#    goes first.
#
# Notes:
#
# * Trailing spaces in the exclude pattern are significant.
#
# * The results in the partial files are rotated and sometimes flipped. So the
#   left column (that goes first) is the lower row in the odd-numbered
#   partials and the higher row in the even-numbered partials.
#
# * The amount of information to specify what to exclude is fairly limited
#   (Two columns of the pattern for one phase.) To avoid excluding more
#   patterns you do not intend to do not be aggressive in trimming the
#   tail.

#exclude+=(--exclude)
#exclude+=(" **   **    *** ***  ***          *   **               **        ****          **     **        *  *     ****   * /  *    ****   **        *   * *          **  *         *         *  *  * **     *               *  *   *    **** *")

Re: A new spaceship search approach

I wonder how well this search approach would work if the width constraint was dropped. From my understanding of the algorithm, this should've be hard to implement. The main issue is whether the number of slices would grow too fast.
\sum_{n=1}^\infty H_n/n^2 = \zeta(3)

How much of current CA technology can I redevelop "on a desert island"?

A search with the following parameters crashed for me:

Code: Select all

margin=14
midline=--odd_midline
parms="--velocity (3,0)c/7 --rule B36/S23"
seedcolumn=03
This message was given, looks like some out of bounds error:

Code: Select all

thread '<unnamed>' panicked at 'index out of bounds: the len is 2379 but the index is 2379', src/compress.rs:58:13
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace
thread 'main' panicked at 'called `Result::unwrap()` on an `Err` value: Any { .. }', src/main.rs:1538:24
If anyone can verify this with their machine, it happened at 0155/11, around 18 hours in (although it would probably be shorter for someone else, I was also running other things.

EDIT, update, I reran this, and it seems fine at 0158/x, so maybe it was some random error on my end.
I manage the 5S project, which collects all known spaceship speeds in Isotropic Non-totalistic rules. I also wrote EPE, a tool for searching in the INT rulespace.

Things to work on:
- Find (7,1)c/8 and 9c/10 ships in non-B0 INT.
- EPE improvements.

I think LSSS with automatic adaptive widening would be the holy grail of oblique spaceship search programs. In 2020-21, Exa made immense progress on (2,1)c/7 with LSSS, but they had to perform the adaptive widening manually, painfully, and suboptimally. I conducted a few searches using this manual procedure, and the partials got really big, really fast (about 10 minutes)!

If you have interesting partial results, please post them in the spaceship discussion thread.
