We consider the problem of maximizing a submodular function on the bounded integer lattice. As a direct generalization of submodular set functions,is submodular, iffor allwhereanddenote element-wise minimum and maximum. The objective is finding a vectorxmaximizingf(x). In this paper, we present a deterministic-approximation using a framework inspired by [2]. We also provide an example that shows the analysis is tight and yields additional insight into the possibilities of modifying the algorithm. Moreover, we examine some structural differences to maximization of submodular set functions which make our problem harder to solve.
