Consider a game in a given set of intervals (and their implied interval graph
*G*) in which the adversary chooses an independent set*X*in*G*. The goal is to discover this hidden independent set*X*by making the fewest queries of the form “Is point*p*covered by an interval in*X*?” Our interest in this problem stems from two applications: experimental gene discovery and the game of Battleship (in a 1-dimensional setting). We provide adaptive algorithms for both the verification scenario (given an independent set, is it*X*?) and the discovery scenario (find*X*without any information). Under some assumptions, these algorithms use an asymptotically optimal number of queries in every instance. **Length**:- The paper is 10 pages.
