In a setting where there is some uncertainty, we ask how to best select $k$ potential solutions, with the goal of optimizing the value of the best solution. More formally, given a combinatorial problem $\\Pi$, a set of value functions $V$ over the solutions of $\\Pi$, and a distribution $D$ over $V$, our goal is to select $k$ solutions of $\\Pi$ that maximize or minimize the expected value of the {\\em best} of those solutions.
