Stanford doesn’t want me. I can say that because it’s a documented fact: I was once denied admission in writing. I took my last math class back in high school. Which probably explains why this quiz on how to get a computer to calculate an ideal itinerary is making my brain hurt. I’m staring at a crude map of Romania on my MacBook. Twenty cities are connected in a network of straight black lines. My goal is to determine the best route from Arad to Bucharest. A handful of search algorithms with names like breadth-first, depth-first, uniform-cost, and A* can be used. Each employs a different strategy for scanning the map and considering various paths. I’ve never heard of these algorithms or considered how a computer determines a route. But I’ll learn, because despite the utter lack of qualifications I just mentioned, I’m enrolled in CS221: Introduction to Artificial Intelligence, a graduate- level course taught by Stanford professors Sebastian Thrun and Peter Norvig.
