Re: JavaLifeSearch
The manual appears to mention the existence of "frozen unchecked" cells, which I should be able to create with X + I, but when I try that on my copy, nothing happens when I press "I". Is the problem with my copy of JLS, the manual, or my own misunderstanding?

Re: JavaLifeSearch
In case you hadn't figured it out yet, this seems to be an error in the documentation. 'i' and 'I' clear all unchecked cells in the selection, and 'o' and 'O' set all unset cells to unchecked. The frozen / unfrozen state is retained with 'i' and 'o' as indicated in the manual  you just need the opposite operation. As usual, 'Shift' applies the operation to all generations.

Re: JavaLifeSearch
How do I use JavaLifeSearch to find a suitable p3 reflector for this?
EDIT: This is p51.
Code: Select all
x = 29, y = 25, rule = B3/S23

Re: JavaLifeSearch
I'm not sure this problem is at a stage where JLS can be used to find a solution, but it depends very much on what you are trying to reflect, the timing of that reflection and where it needs to go. If I understand what you are trying to do correctly, then you want to use the p3 reflector to shuttle the glider which knocks out the FNG of the eastern herschel allowing the R> H progression to work. What you need to do first is work out the timing and output lane of the reflector that's required, and then survey all the known p3 reflectors to see if there's anything that matches. If you find something but it doesn't fit, then you can use JLS to find an oscillator which uses the same mechanism and also fits in the space that is available. If there's nothing that matches then it is going to be very hard to find something starting with just JLS.Entity Valkyrie wrote:How do I use JavaLifeSearch to find a suitable p3 reflector for this?

If you do want to tackle this problem then the way to do it would be to set up JLS with a period of 51 gen, and manually set the as much of the pattern as possible until you have the input and output gliders defined throughout the interaction. In this case you may need to work forwards from Gen 0 and backwards from the last gen to work out where and when the interaction will take place. In the middle you'll need to leave a number of cells unconstrained (which is where the interaction will take place) and then border that region with cells constrained to be p3. To start with there should be a thin border of p3 cells surrounded by a larger area of Unchecked p3 cells. I tackle these problems by starting with as small an area as possible for the interaction and gradually increase that area when no results are found. You'll see that there are errors where signals (including gliders) come into and go out of the conduits. These errors can be resolved with Unset cells in the last generation.
You can save a lot of time in setting up these searches by pasting in a pattern from Golly into JLS, manually setting the unknown areas throughout the evolution and letting it work out the subsequent generations everywhere else. I've attached a JLS file which sets up this kind of search from an adapted version of the pattern on the Gun Discussion thread (with alternate p3 sparker) combined with the pattern here. With the current setup the search finds 0 solutions after about 3 minutes. Note the Sort order used (in particular "Process all cells in a generation first") and the use of "Use combinations of solutions to prune search" in the Search Options. The later option has no effect on this search as it's set up, but as you expand the search it's a very useful option.
I suspect that even if you manage to find a solution to this problem it's going to be very difficult to make it fit with all the other circuitry you require, for example, there's no way it can coexist with the 2G > H you used in the pattern from the Gun Discussion thread.
Good Luck

Re: JavaLifeSearch
JLS's error detection is buggy when finding spaceships. For example, it prevents me from attempting to extend the following c/5o partial because of the top three sparks:

Re: JavaLifeSearch
This partial seems to work fine for me in JLS, but the search doesn't go very far before it's complete. Here are the settings which need to be adjusted from default to run a search (with the partial in the same orientation as shown above):LaundryPizza03 wrote: ↑March 2nd, 2020, 1:45 amJLS's error detection is buggy when finding spaceships.

 Edit > Properties > Edit field:
 Columns (width)  21 (or slightly larger odd value)
 Rows (height)  some number larger than 18 (50 is reasonable, less is OK, more gets awkward but will be necessary for long ships)
 Generations (depth)  5
 Symmetry  Horizontal mirror
 Edit > Properties > Tiling/translation
 After the last generation is... Generation 0, shifted 1 cells down

 B3/S3 (deselect S2)
 Select the top 14 rows and press 'a' to set cells to Off.
 Select the centre 19 columns of the top 14 rows and paste the partial pattern (Edit > Paste or CtrlV)
 In order to run any reasonable search you also need to change the search order  Search > Options > Sorting
 Area  Vertical
 (Optional) Start at Column 10 (Should be the centre column [(width  1) / 2] )
 Search > Options > Processing
 Display search status on screen  every 1 seconds (Personal preference)
Personally I find searching for vertically traveling spaceships in JLS / WLS awkward  the defaults are more tailored to leftward traveling ships. To set up such a search you just need to adjust the period, the displacement (set "After the last generation is..." to Generation 0, shifted x cells to the right, where "x" is the desired displacement), and set symmetry to Vertical mirror (if desired). (And optionally change the sorting options to Start at Row r, where r is the centre row.)
I don't understand what you mean  you can't run an oscillator search with this partial...EDIT: Without the spaceship requirement, do you know why I'm getting only solutions where the rows behind the last functional one disappear after 1 period?

Re: JavaLifeSearch
The spaceship search option is still proving unusably buggy for me. I'm trying to find a glidesymmetric 2c/8d in B368/S35678 by attaching a rear end to a wickstretcher. The spaceship is traveling northwest, so the correct option is to have the pattern shifted up 1 cell and left 1 cell, reflected diagonally backward. But then the ten cells highlighted in red and white at the northwest end of the pattern return an error, despite working exactly as intended. Even when specifying simple translation, it still doesn't work.
That said, JLS works fine for searches that don't involve unknown moving patterns, though I'd still like to build a GUI for custom LLS searches because it's faster and more diverse.

Re: JavaLifeSearch
Unfortunately JLS doesn't fully support diagonal glide reflect spaceships. There was a brief mention of this issue at the end of page 1 of this thread. I'm not sure about the partial you are trying to extend (because you haven't shown it here) but as you note glide reflect with (1,1) does work in this rule. The glider in CGoL is glide reflect with (1,0) and that doesn't work in JLS. Similarly, 2c/8d spaceships could be glidereflect with (2,0), and that doesn't work in JLS. It could be that your partial requires (2,0) rather than (1,1).LaundryPizza03 wrote: ↑May 12th, 2020, 2:03 amThe spaceship search option is still proving unusably buggy for me.
