The Price of Anarchy

Braess' paradox and the price of anarchy [PDF]: "We had three tunnels in the city and one needed to be shut down. Bizarrely, we found that car volumes dropped. ... We discovered it was a case of Braess' paradox, which says that by taking away space in an urban area you can actually increase the flow of traffic, and, by implication, by adding extra capacity to a road network you can reduce overall performance." The Price of Anarchy in Transportation Networks is the paper mentioned in the first link — see that for maps of Boston, London, and Manhattan that show which roads were beneficial to block (individually) in a simulation. If you are interested in selfish networks and are not afraid of math, check out Selfish Routing and the Price of Anarchy (review) as well as this paper for some bounds on the price of anarchy.

In the future, we're still all raging dirtbags.

Tit-for-tat dethroned in iterated prisoner's dilemma competition! But it might not work so well in RL, and what if you threw in QM? :D
