- I've heard this called the 'princess problem' and it is completely worked
- out in Sheldon Ross's _Introduction to Stochastic Dynamic Programming_
- which is a smart little volume, BTW.
-
- The general strategy to pick among n suitors is to pass on the first n/e
- and then pick the first one you encounter which is better than what you've
- seen so far. Your chances of getting the best one are about 1/e, which is
- surprisingly large.
-
- It might make more sense to minimize the down side on this one, however...
