Abstract

As usual, this feature begins with several speed puzzles; answers can be found at the end of the problems. Following is one longer puzzle for which readers are challenged to submit their own answer. The puzzles in this issue focus on everything from diversifying strategies in naval warfare to ordering in restaurants to finding the quickest way around Delhi. The column ends with reader mail, including submitted solutions to Schelling's Poison Pill and the fairest way to score a contest.
