AI designed DOOM levels so good they seem man-made

Video games these days are contingent on their realistic, detailed, immersive worlds. But building that takes lots of programmers many hours; Vice City, after all, was not built in a day. What if an AI could do some of the heavy lifting (so to speak) instead? Computer scientists at Italy's Politecnico di Milano found a way to let AI handle all the difficult parts of level design so that designers and gamers alike can get to the fun parts more quickly. The 1993 first-person shooter DOOM was a natural place to start. People run the thing on as much technology as possible -- there are people out there who will figure out how to run the game on anything with an operating system, from a thermostat to a calculator.
