Glider controll?

Post by Monocot » June 30th, 2012, 2:02 pm

Hi there!

I recently started dabbling around with GoL, and found this:

Code: Select all

x = 11, y = 66, rule = B3/S23
$2b2obob2o$3bobobo$3bobobo$2b2obob2o$3bobobo$3bobobo$2b2obob2o$3bobobo

ob2o$3b2o2bo$6b2o!
(The stable end is from the "Cow"-wick from the LifeWiki, IIRC)

With an additional bit of fiddling, I found a fuse and a way to burn it cleanly:

Code: Select all

x = 9, y = 212, rule = B3/S23

With additional fiddling around the gliders can go the other way, and one can leave holes in the gliderstream:

x = 9, y = 116, rule = B3/S23
$b2obob2o$2bobobo$2bobobo$b2obob2o$4bo$b2obob2o$2bobobo$2bobobo$b2obob

Now, just for fun, I would like to use some instable ("clean-burning") glider reflectors (e.g. toads) to reflect the glider-output of these wicks/fuses (?) to build something - I thought about a Gosper Glider Gun for a start.

It easy enough to find a glider collusion for Gosper Glider Guns - but how do I work out the glider trajectories the best way? It's hard enough (for me) to get the timing of a glider and a toad precisely. Are there any tricks/programs/hints for a newbie?

Thanks in advance!

There is a reaction involving a boat and a glider, where the boat is destroyed cleanly and the glider is reflected 90 degrees.

The same is true for a fishhook eater, and also a long boat (four different paths, 90 or 180 degrees reflection). And there are literally thousands of small constellations of random junk that will also reflect a glider. Millions or billions, actually, for large enough definitions of "small".

There's no search program for this kind of thing yet, that I know of, but here are a few tricks and hints:
  • 1. Look at Golly's Patterns/Life/Syntheses/blockic-and-blockish-seeds.rle. Down the middle there's a collection of what you called "instable glider reflectors" (I called them "one-time turners" in the comments, I think.) You could figure out the timings to add to this list the toad, boat, long boat, eater, and whatever other turners you find... or you could just stick with these blocks-only reflectors -- there's enough variety there to get the job done.

    2. You might try using Golly's LifeHistory rule to make it easier to line up the reflector constellations with your glider outputs. The Blockic turner table ends up looking like this:

    Code: Select all

    #C one-time reflectors sorted by speed and output glider color
    x = 152, y = 405, rule = LifeHistory

    3. The reflectors on the left preserve the glider checkerboard-square color; the ones on the right change it. The little dots and dominos to the right of the reaction areas show where the line of reflection is.

    4. To make things simpler, start with just the two reflectors with a timing of zero. Wire up the gliders from your fuse (the Life Lexicon says it's only a wick until you start burning it...!) to appropriate chains of 0-turners, until the final output gliders are on the same lanes as the gliders in your Gosper gun recipe.
    • 4a. It's safer to include a 180-degree turn in each chain, with plenty of space for adjustment outward (i.e. slowing the glider down). It's more impressive if you can avoid 180-degree turns altogether -- but if you use the 180-degree 0-turners from the following table, it will make it easier later on:

    5. Convert all the gliders in the gun recipe to state 4 (red) in LifeHistory, so you can see your targets but they won't move when you test the pattern, and they won't affect the real gliders when they arrive.

    6. Now the gliders are all getting to the construction site, but the timings are all wrong -- except for one. Find the glider that arrives at its target location last, and call that one "the right timing".

    7. Pick a wrong-timed glider, and figure out exactly how many ticks too fast it is -- T ticks, let's say.
    • 7a. If you've used 180-degree bends on all wrong-timed glider paths, as #4a advised, then simply move the 180-degree turner out |T/8| cells diagonally. Then replace that turner with another one from the same column in the table (if necessary), with a delay rating of T mod 8. That glider should now be right on target, synchronized with the right-timed glider.

      7b. If you're not cheating by using 180-degree bends everywhere, replace 0-turners in the glider's path with other turners with different delay ratings. The sum of all your new delay ratings should be exactly T ticks.
    8. Repeat for all the other wrong-timed gliders.

    9. You're all done! (Less than ten steps -- easy, right?) Use this script to clean up the LifeHistory cells:

    Code: Select all

    # Switch current pattern from LifeHistory to standard Conway's Life rule
    import golly as g
    if g.getrule()=="LifeHistory" or g.getrule()=="HistoricalLife":
       # unmark any marked cells
       cells=g.getcells(g.getrect())
       for i in xrange(2,len(cells), 3):
          cells[i]=cells[i]%2
       g.select(g.getrect())
       g.clear(0)
       g.select([])
       g.putcells(cells)
    g.setrule("Life")
    g.setalgo("HashLife")
