Darwin: Celebrating 50 Years of Programming Games

screenshot from Darwin-80
Darwin was the earliest programming game, invented by Victor Vyssotsky in August 1961. The idea of the game was to write a program to out-replicate and disable all opponents.

Each program had a number of protected locations and interacted via three functions:

  • PROBE - return the start, end and owner of a memory block
  • CLAIM - reserve memory
  • KILL - disable a program

If a protected location was PROBEd the current program lost control. A CLAIM or KILL could only be used on a location which had previously been PROBEd.

Douglas McIlroy coded Darwin on Bell Labs' IBM 7090 and the game slowly progressed until an unbeatable program emerged, designed by Robert Morris.

Robert's program used an adaptive search. If the program PROBEd an opponent and lost control it would avoid reusing the same offset. A successful offset would be stored then used for future PROBEs and to initialise new copies of itself. Robert's program adapted to become a specialist killer.

In 1972 0 (Aleph-Null) published the rules of Darwin in Software Practice and Experience, inspiring a number of new implementations. In 1987 Gerald Edgar published his 8080 version to accompany an article in Computer Language.

Unfortunately Darwin faced a major problem. Programs were written in machine language and could only compete against others written for the same computer. When A. K. Dewdney introduced Core War in 1984 he addressed the limitation by defining the MARS virtual computer and Redcode, a simplified assembly language.

Although Darwin has been consigned to the history book, I'll never grow tired of reading about it! Do you remember playing Darwin? If so, I'd love to hear the details.

  3. I wish I would have gotten this deep into computer programming and game programming. I've made some good old fashioned games using basic and a few others, and I've experimented a lot with how computers work. But I've never done anything like this. It sounds like some of the best fun.

  9. People often have trouble understanding the word "tradeoff", sure enough it's easy enough to understand as exchange but in today's corporate parlance it is meant as exchange of one commodity as a cost for another. I was playing Final Fantasy's Dissidia on the good old PSP yesterday when I marveled at the game's replay value, yes I have spent over 50 hours on it already, which is what this entire topic is all about. Normally Mario Kart Wii Characters you look at the oldest games like Mario and Dave, they had one thing unanimously common, addiction to it.

  33. Narcopaths (malignant narcissists, narcissistic sociopath) are masters at playing mind games. They play to win and take no prisoners. They are sore losers and if they don't win they will often react in a fit of rage and stomp away like a little child. I have to say upfront, I am not comfortable calling what a narcopath does to us as games, but I can't think of a better alternative. I used manipulation characterized as games, but that's a mouthful. Anyway, every therapist I've talked with uses the term, so I will, too. When I think of games, I think of fun, laughter and enjoying myself. Nothing about my experience with the narcopath comes even close, so it's hard for me to think of the narcopath and games in the same setting. Polar opposites in my mind. Car Parking Simulator Review
