Research Type Theoretical In this paper we develop the novel technique of correlated (interleaved) scheduling, which allows us to obtain a polynomial-time (1 - 1/e)-approximation algorithm (asymptotically and in expectation) for any matroid. Along the way, we discover an interesting connection to a variant of Submodular Welfare Maximization, for which we provide (asymptotically) matching upper and lower approximability bounds.

Pseudocode Yes Algorithm 3.1 (INTERLEAVED-SUBMODULAR (IS)). For each element i ∈ A, let ri ∼ U[0, 1] be a random offset drawn uniformly from [0, 1]. At every round t = 1, 2, . . . , let At ⊆ A be the subset of elements such that for any i ∈ At, the interval Li,t = [t − 1/di + ri, (t + 1) − 1/di + ri) contains an integer. Choose the elements At and collect the reward f(At).
