A function $f: mathbb{Z}_+^E rightarrow mathbb{R}_+$ is DR-submodular if it satisfies $f(bx + chi_i) -f (bx) ge f(by + chi_i) - f(by)$ for all $bxle by, iin E$. Recently, the problem of maximizing a DR-submodular function $f: mathbb{Z}_+^E rightarrow mathbb{R}_+$ subject to a budget constraint $|bx|_1 leq B$ as well as additional constraints has received significant attention cite{SKIK14,SY15,MYK15,SY16}. In this note, we give a generic reduction from the DR-submodular setting to the submodular setting. The running time of the reduction and the size of the resulting submodular instance depends only emph{logarithmically} on $B$. Using this reduction, one can translate the results for unconstrained and constrained submodular maximization to the DR-submodular setting for many types of constraints in a unified manner. |
