n. A game between 'Assembler' programs in a
simulated machine, where the objective is to kill your opponent's
program by overwriting it. Popularized by A. K. Dewdney's column
in 'Scientific American' magazine, this was actually
devised by Victor Vyssotsky, Robert Morris, and Dennis Ritchie in
the early 1960s (their original game was called 'Darwin' and ran on
a PDP-1 at Bell Labs).
See core.
