Milind Tambe, a specialist in artificial intelligence, led a team of USC researchers in applying game theory insights to systematically make it extremely difficult for observers to find any patterns or regularities in LAX vehicle security routines.

The result is a software package with a computer interface showing a blank schedule, with a button labeled "randomize." Pressing the button produces a set of times and places for security forces to be, a schedule that produces the same level overall coverage as conventional scheduling but does so unpredictably.
Interesting stuff, but I'm not sure how randomization in-and-of-itself (whether of security patrols, or of travel routes, or anything else) is particularly an insight of game theory--it has been a part of security and intelligence tradecraft since (I suspect) the dawn of time.

Of course, I can see how computer-based randomization that takes into account geographic coverage, shift durations, travel times, might be a more efficient way of doing it.
