Consider the computer’s advantage. Suppose we were examining the North Korean nuclear problem in 2004, as I was, and suppose we simplified it (which I didn’t) to consider just five players: George W. Bush, Kim Jong Il, Russia’s Vladimir Putin, China’s Hu Jintao, and South Korea’s Roh Moo Hyun (ignoring Japan for the moment). How many conversations among the parties to the talks might each of those five decision makers want to know about?
