Greedy Sensor Selection for Weighted Linear Least Squares Estimation Under Correlated Noise

open access: yesIEEE Access, 2022
Optimization of sensor selection has been studied to monitor complex and large-scale systems with data-driven linear reduced-order modeling. An algorithm for greedy sensor selection is presented under the assumption of correlated noise in the sensor ...

Optimizing Household Waste Recycling Centre Network Reorganization in Hampshire

open access: yesNetworks, Volume 88, Issue 3, Page 313-330, October 2026.
ABSTRACT Local councils across the UK are facing sustained financial pressures, and Household Waste Recycling Centres (HWRCs) are being increasingly considered for closure to reduce expenditure. In 2024, Hampshire County Council, which operates the largest HWRC network in the UK, proposed closing either five or twelve existing sites.

Approximation Algorithms for Maximization of k-Submodular Function Under a Matroid Constraint

open access: yesTsinghua Science and Technology
In this paper, we design a deterministic 1/3-approximation algorithm for the problem of maximizing non-monotone k-submodular function under a matroid constraint.

Security Design Under Common‐Value Competition

open access: yesEconometrica, Volume 94, Issue 5, Page 1717-1759, September 2026.
This paper studies security design by bidders with dispersed information about a common‐value investment opportunity. Among a broad set of securities, bidders offer debt financing—the flattest securities. A first reason is that debt mitigates bidders' exposure to the winner's curse when there are two bidders.

Towards Minimizing k-Submodular Functions

open access: yes, 2012
In this paper we investigate k-submodular functions. This natural family of discrete functions includes submodular and bisubmodular functions as the special cases k = 1 and k = 2 respectively.

Reconsidering Volume‐Based Drug Procurement Policy: The Consequences of Manufacturers' Optimal Production Planning and Breach Strategies

open access: yesNaval Research Logistics (NRL), Volume 73, Issue 5, Page 743-763, August 2026.
ABSTRACT This paper examines the impacts of Volume‐Based Procurement (VBP) policies on pharmaceutical supply chains, with a focus on the strategic behaviors of manufacturers. VBP aims to reduce costs and stabilize supplies by centralizing procurement through competition based on volumes and prices.

Metric learning with submodular functions

open access: yesNeurocomputing, 2020
Abstract Most of the metric learning mainly focuses on using single feature weights with Lp norms, or the pair of features with Mahalanobis distances to learn the similarities between the samples, while ignoring the potential value of higher-order interactions in the feature space.

New Query Lower Bounds for Submodular Function Minimization [PDF]

open access: yes, 2020
We consider submodular function minimization in the oracle model: given black-box access to a submodular set function f:2^[n] → ℝ, find an element of arg min_S {f(S)} using as few queries to f(⋅) as possible. State-of-the-art algorithms succeed with Õ(n²)
