Multi-objective Evolutionary Algorithms are Still Good: Maximizing Monotone Approximately Submodular Minus Modular Functions [PDF]

open access: yes, 2022
As evolutionary algorithms (EAs) are general-purpose optimization algorithms, recent theoretical studies have tried to analyze their performance for solving general problem classes, with the goal of providing a general theoretical explanation of the ...

Multiuser computation offloading for edge-cloud collaboration using submodular optimization

open access: yesTongxin xuebao, 2020
A computation offloading scheme based on edge-cloud computing was proposed to improve the system utility of multiuser computation offloading.This scheme improved the system utility while considering the optimization of edge-cloud resources.In order to ...

How to see the forest despite the trees

open access: yesJournal of the London Mathematical Society, Volume 114, Issue 2, August 2026.
Abstract One of the major starting points of discrete optimization is the theorem of Nash‐Williams and Tutte on the existence of k$k$ disjoint spanning trees of a graph, along with its counterpart on the existence of k$k$ forests covering all edges of the graph.

Lower bounds for cube‐ideal set‐systems

open access: yesProceedings of the London Mathematical Society, Volume 133, Issue 2, August 2026.
Abstract A set‐system S⊆{0,1}n$S\subseteq \lbrace 0,1\rbrace ^n$ is cube‐ideal if its convex hull can be described by capacity and generalized set covering inequalities. In this paper, we use combinatorics, convex geometry, and polyhedral theory to give exponential lower bounds on the size of cube‐ideal set‐systems, and linear lower bounds on their ...

On Unconstrained Quasi-Submodular Function Optimization

open access: yesProceedings of the AAAI Conference on Artificial Intelligence, 2015
With the extensive application of submodularity, its generalizations are constantly being proposed. However, most of them are tailored for special problems. In this paper, we focus on quasi-submodularity, a universal generalization, which satisfies weaker properties than submodularity but still enjoys favorable performance in ...

Optimal design and operation of damping controllers in PV–wind integrated sustainable energy grids considering system uncertainties

open access: yesIET Renewable Power Generation, 2023
This paper aims to present an optimization method for the best bus selection (BBS) in the large‐scale power systems in order to send the input signals to the damping controllers.

Efficient investment, search, and sorting in matching markets

open access: yesTheoretical Economics, Volume 21, Issue 3, Page 810-848, July 2026.
We study markets where heterogeneous agents first make investment decisions and then engage in a costly search to form productive matches. The trading process is a random search and bargaining with explicit search costs. Despite potential hold‐up and matching problems, we prove that the constrained efficient allocation is an equilibrium: the agents ...

Entity Canonicalization Method Based on Dual-View Contrastive Learning and Submodular Optimization [PDF]

open access: yesJisuanji gongcheng
Entity redundancy, where multiple nodes represent the same real-world entity due to heterogeneous data sources or extraction errors, severely affects the quality and utility of Knowledge Graphs (KG). To address the problem of Entity Canonicalization (EC)
