Approximation Algorithms for Stochastic Submodular Set Cover with Applications to Boolean Function Evaluation and Min-Knapsack [PDF]

open access: yesACM Transactions on Algorithms, 2016
We present a new approximation algorithm for the stochastic submodular set cover (SSSC) problem called adaptive dual greedy . We use this algorithm to obtain a 3-approximation algorithm solving the stochastic Boolean function evaluation (SBFE) problem for linear threshold formulas (LTFs).

Generalized budgeted submodular set function maximization [PDF]

open access: yesInformation and Computation, 2021
In this paper we consider a generalization of the well-known budgeted maximum coverage problem. We are given a ground set of elements and a set of bins. The goal is to find a subset of elements along with an associated set of bins, such that the overall cost is at most a given budget, and the profit is maximized.

Quantitative approximation by nonlinear Angheluta-Choquet singular integrals

open access: yesJournal of Numerical Analysis and Approximation Theory, 2020
By using the concept of nonlinear Choquet integral with respect to a capacity and as a generalization of the Poisson-Cauchy-Choquet operators, we introduce the nonlinear Angheluta-Choquet singular integrals with respect to a family of submodular set ...

Improved Lower Bounds for Submodular Function Minimization [PDF]

open access: yesIEEE Annual Symposium on Foundations of Computer Science, 2022
We provide a generic technique for constructing families of submodular functions to obtain lower bounds for submodular function minimization (SFM). Applying this technique, we prove that any deterministic SFM algorithm on a ground set of n elements ...

An Improved Approximation Algorithm for the Minimum Power Cover Problem with Submodular Penalty

open access: yesComputation, 2022
In this paper, we consider the minimum power cover problem with submodular penalty (SPMPC). Given a set U of n users, a set S of m sensors and a penalty function π:2U→R+ on the plane, the relationship that adjusts the power p(s) of each sensor s and its ...
