Research Type Theoretical Our work presents a simple but powerful framework for designing online learning algorithms for PANDORA S BOX, MSSC and other related problems. Our framework yields approximately low-regret algorithms for these problems through a three step process: 1. We first obtain convex relaxations of the instances of every round. 2. We then apply online-convex optimization to obtain good fractional solutions to the relaxed instances achieving low regret. 3. We finally round the fractional solutions to integral solutions for the original instances at a small multiplicative loss. Through this framework, we obtain a 9.22-approximate no-regret algorithm for the problem of selecting 1 box. O(1)-approximate no-regret algorithm for the problem of selecting k boxes. O(log k)-approximate no-regret algorithm for the problem of selecting a rank k matroid basis.
