2 | #D Still-Life Reflector |
||
3 | #D |
||
4 | #D Converts one glider into 4 for any input stream |
||
5 | #D with a period of 672 or greater, unless pipelining |
||
6 | #D techniques are employed. It is a great challenge |
||
7 | #D to come up with the small, fast reflector that |
||
8 | #D consists solely of still-lifes. Dieter Leithner |
||
9 | #D (dietrich.deithner@dlr.de) is offering a $100 |
||
10 | #D prize for the first stable glider reflector that |
||
11 | #D fits within a 50x50 box. |
||
12 | #D |
||
13 | #D A glider collides with a boat in generation 97, |
||
14 | #D destroying the boat but creating a B-heptomino at |
||
15 | #D generation 107. This is converted into a Herschel |
||
16 | #D in 59 generations. Herschel conduits of lengths 64, |
||
17 | #D 77, 77, 64, 64, 77, 119, and 64 set the Herschel up |
||
18 | #D for a final collision to recreate the destroyed |
||
19 | #D boat. |
||
20 | #D |
||
21 | #D The first stable glider reflectors were created by |
||
22 | #D Paul Callahan and Dean Hickerson in late 1996. This |
||
23 | #D one by Dave Buckingham, May 30, 1997. |
