Optimization of Submodularity and BBO-Based Routing Protocol for Wireless Sensor Deployment
Sensors, 2020 Wireless sensors are limited by node costs, communication efficiency, and energy consumption when wireless sensors are deployed on a large scale. The use of submodular optimization can reduce the deployment cost.

Optimizing Household Waste Recycling Centre Network Reorganization in Hampshire
Networks, 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.

CrossPatch-Based Rolling Label Expansion for Dense Stereo Matching
IEEE Access, 2020 We present a novel algorithm called crosspatch-based rolling label expansion for accurate stereo matching. This optimization-based approach can effectively estimate the 3D label of each pixel from huge and infinite label space and then generate a ...

Randomization-Embedded Greed: Pursuing More Platform Profits in Mobile Crowd Sensing
IEEE Access, 2018 The recent proliferation of sensor-equipped mobile phones, together with the intrinsic mobility of their users, has enabled mobile crowdsensing (MCS) to spring up. In a typical MCS system, the MCS platform recruits mobile phone users (workers) to perform

Bicriteria Algorithms for Approximately Submodular Cover Under Streaming Model
Tsinghua Science and Technology, 2023 In this paper, we mainly investigate the optimization model that minimizes the cost function such that the cover function exceeds a required threshold in the set cover problem, where the cost function is additive linear, and the cover function is non ...

Naval Research Logistics (NRL), Volume 73, Issue 5, Page 810-835, August 2026.ABSTRACT We are concerned with the stability of a transferable‐utility cooperative (TU) game. First, the concept of core can be weakened so that the blocking of changes is limited to only those with multilateral backings. This principle of consensual blocking, as well as the traditional core‐defining one of unilateral blocking and one straddling in ...

Mobility-Aware Traffic Offloading via Cooperative Coded Edge Caching
IEEE Access, 2020 With caching popular contents at the small-cell base stations (SBSs), cooperative edge caching has emerged as an effective approach to offload explosively increasing network traffic from a massive number of users in mobile edge networks (MENs).

Outbreak detection for temporal contact data
Applied Network Science, 2021 Epidemic spreading is a widely studied process due to its importance and possibly grave consequences for society. While the classical context of epidemic spreading refers to pathogens transmitted among humans or animals, it is straightforward to apply ...

Optimal Selling Mechanisms With Endogenous Seller Outside Offers
International Economic Review, Volume 67, Issue 3, Page 875-891, August 2026.ABSTRACT We examine a two‐stage selling mechanism design problem, where the buyer makes her report and the seller endogenously decides his effort (hidden investment) to generate a possibly better outside offer. The optimal mechanism shows that the seller's effort depends on the reported value of the buyer; a higher value lowers the seller's incentive ...
