1. Knights on a Line: Three feudal lords are vying for control of a piece of territory in the shape of a line segment, denoted by the interval [0, 1]. Let each lord have a utility function u(t) that increases with the amount of territory they control. In order to claim territory, the lords must command the loyalty of the peasants who are uniformly distributed and spread throughout the land. Each lord can secure the loyalty of the peasants by deploying a knight somewhere in the territory; peasants will pledge their loyalty to whichever lord's knight is closest to them and choose a lord to support at random in the event of a tie. Each of the three lords decides at the same time where to place their knight. Lords are not allowed to withhold their knights; they must be deployed.
