Core Wars: n. A game between `assembler' programs in a machine
or machine simulator, where the objective is to kill your opponent's
program by overwriting it. Popularized in the 1980s by A. K.
Dewdney's column in "Scientific American" magazine, but described in
"Software Practice And Experience" a decade earlier. The game was
actually devised and played by Victor Vyssotsky, Robert Morris Sr.,
and Doug McIlroy in the early 1960s (Dennis Ritchie is sometimes
incorrectly cited as a co-author, but was not involved). Their
original game was called `Darwin' and ran on a IBM 7090 at Bell
Labs. See core. For information on the modern game, do a web
