Balanced sets in an independence structure induced by a submodular function [PDF]

open access: yesJournal of Mathematical Analysis and Applications, 1983
AbstractA submodular (and non-decreasing) function on a set induces an independence structure; the notion of a “balanced” set in this situation helps us determine whether a given independence structure is induced by any submodular function other than its own rank function, answering a question of U. S. R. Murty and I. Simon.

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 ...

A balanced sensor scheduling for multitarget localization in a distributed multiple-input multiple-output radar network

open access: yesInternational Journal of Distributed Sensor Networks, 2021
In this article, we consider the problem of optimally selecting a subset of transmitters from a transmitter set available to a multiple-input and multiple-output radar network.

Constrained Path Search with Submodular Function Maximization [PDF]

open access: yes, 2022
In this paper, we study the problem of constrained path search with submodular function maximization (CPS-SM). We aim to find the path with the best submodular function score under a given constraint (e.g., a length limit), where the submodular function ...

Fast and exact search for the partition with minimal information loss. [PDF]

open access: yesPLoS ONE, 2018
In analysis of multi-component complex systems, such as neural systems, identifying groups of units that share similar functionality will aid understanding of the underlying structures of the system.

Single Machine Vector Scheduling with General Penalties

open access: yesMathematics, 2021
In this paper, we study the single machine vector scheduling problem (SMVS) with general penalties, in which each job is characterized by a d-dimensional vector and can be accepted and processed on the machine or rejected.

Monotone Submodular Maximization over a Matroid via Non-Oblivious Local Search [PDF]

open access: yes, 2013
We present an optimal, combinatorial 1−1/e approximation algorithm for monotone submodular optimization over a matroid constraint. Compared to the continuous greedy algorithm (Calinescu, Chekuri, Pál and Vondrák, 2008), our algorithm is extremely simple ...

Hardness of submodular cost allocation : lattice matching and a simplex coloring conjecture [PDF]

open access: yes, 2014
We consider the Minimum Submodular Cost Allocation (MSCA) problem. In this problem, we are given k submodular cost functions f1, ... , fk: 2V -> R+ and the goal is to partition V into k sets A1, ..., Ak so as to minimize the total cost sumi = 1,k fi(Ai).

Streaming Algorithms for News and Scientific Literature Recommendation: Monotone Submodular Maximization With a $d$ -Knapsack Constraint

open access: yesIEEE Access, 2018
Submodular optimization plays a significant role in combinatorial problems, since it captures the structure of the edge cuts in graphs, the coverage of sets, and so on. Many data mining and machine learning problems can be cast as submodular maximization
