Decompositions [GAME]

So we all know syntheses, but what about decompositions?
To "decompose" something (in this game) is when you take a stable object like so

Code: Select all

x = 3, y = 4, rule = B3/S23
bo$obo$obo$bo!
and place any amount of the same object to turn it into gliders (more than one glider is accepted and supported)

Code: Select all

x = 11, y = 11, rule = B3/S23
b2o$o2bo$b2o$6bo$2bo2bobo$bobobobo$bobo2bo$2bo6bo$8bobo$8bobo$9bo!
The starting pattern is

Code: Select all

x = 6, y = 6, rule = B3/S23
4bo$3bobo$2bo2bo$bob2o$bo$2o!

This does sort of ruin the fun, but I hacked together a script to do it automatically:

Code: Select all

import lifelib
sess = lifelib.load_rules('b3s23')
lt = sess.lifetree(n_layers = 1, memory = 1000)
transformations = ['identity', 'rot270', 'rot180', 'rot90', 'flip_x', 'flip_y', 'swap_xy', 'swap_xy_flip']
import random
def addpt(pt):
    pt += basept(random.choice(transformations))(random.randint(-placearea, placearea), random.randint(-placearea, placearea))[random.randint(0, period-1)]
    return pt
rle = input('Enter headerless RLE of pattern.\n>')
objs = int(input('How many objects do you want to place?\n>'))
basept = lt.pattern(rle)
bbox = basept.bounding_box
placearea = round(max(bbox[2], bbox[3]) * 2.2)
period = basept.period
componentnums = [len(basept[x].components()) for x in range(period)]
min_components = objs * min(componentnums)
max_components = objs * max(componentnums)
for n in range(1000000):
    if (n+1)%1000 == 0:
        print(str(n+1)+'/1000000 solutions tested.')
    pt = lt.pattern('b!')
    for x in range(objs):
        pt = addpt(pt)
    if len(pt.components()) >= min_components and len(pt.components()) <= max_components:
        if pt[200].population == 5:
            if pt[200].wechsler in ['153', '163']:
                print('#C Solution found:')
                print(pt.rle_string())
                break
An example solution using three copies:

Code: Select all

#CLL state-numbering golly
x = 12, y = 16, rule = B3/S23
2b2o$bo2bo$2bobo$3bo$4b3o3bo$6bo2bobo$8bo2bo$7bob2o$7bo$6b2o$4bo$
3bobo$2bo2bo$bob2o$bo$2o!
It is quite slow, but it gets there in the end for small objects:

Code: Select all

x = 15, y = 15, rule = B3/S23
3b2o$3bobo$5bo$b4o$o$obo3b2o$b2o2bo2bo$5bob2o$2b2obo6b2o$2bo2bo6bobo$

I just did it myself:
