An effective and efficient matheuristic for the electric vehicle routing problem with capacitated recharging stations

open access: yesInternational Transactions in Operational Research, EarlyView.
Abstract In this paper, we address the problem of routing a fleet of electric vehicles (EVs) to serve a set of customers, geographically distributed, within their time windows. We assume that EVs may also be recharged en route, and the amount of energy recharged at a recharging station (RS) is a decision variable itself, that is, partial recharges are ...

Games for the Optimal Deployment of Security Forces [PDF]

open access: yes, 2019
In this thesis, we develop mathematical models for the optimal deployment of security forces addressing two main challenges: adaptive behavior of the adversary and uncertainty in the model. We address several security applications and model them as agent-

Vessel arrival planning with full information

open access: yesInternational Transactions in Operational Research, EarlyView.
Abstract Planning efficiency and timely arrival of vessels is crucial to smooth operations of maritime transport networks, ensuring optimal utilization of resources and minimizing operational costs. Coordination between vessel operators and terminals has the potential to reduce costs, fuel consumption, and waiting time.

Detecting Informed Trading Risk from Undercutting Activity

open access: yesThe Journal of Finance, EarlyView.
ABSTRACT We introduce a simple measure of informed trading risk, QIDres$QID^{res}$, the residual to liquidity quote‐improvement‐to‐deterioration ratio times −1$-1$. When facing with increased informed trading risk, liquidity providers compete less to provide liquidity, reducing their undercutting activity. Reductions in undercutting leave footprints in

Superlative Objoid Constructions in British and American English

open access: yesWorld Englishes, EarlyView.
ABSTRACT This paper investigates regional variation in Superlative Objoid constructions (SOCs) and their prepositional variant (at‐SOCs). SOCs combine a possessive pronoun with a superlative adjective. These function as manner‐degree modifiers in a context where the possessive is in postverbal position and correlative with the subject, as in they tried

Building centaur responders: is emergency management ready for artificial intelligence?

open access: yesDisasters, Volume 50, Issue 3, July 2026.
Abstract This article examines the preparedness of emergency management (EM) for addressing questions pertaining to artificial intelligence (AI), encompassing its benefits to EM missions, the potential biases, the societal impacts, and more. We pinpoint two key shortcomings in early EM research on AI: (i) insufficient discussion of both AI's history ...

A Trust‐Based Random Forest Approach for Detecting Blackhole Attacks in Vehicular Ad Hoc Networks

open access: yesEngineering Reports, Volume 8, Issue 6, June 2026.
A multi‐metric trust framework combined with Random Forest learning detects and mitigates blackhole attacks in VANETs. By dynamically isolating malicious vehicles, the model sustains high packet delivery, low latency, and accurate intrusion detection under severe attack conditions.

Dynamic Search‐Based Cluster Head Selection Method for Resource Occupation Protection Switching in Optical Fiber Communication Networks

open access: yesEngineering Reports, Volume 8, Issue 6, June 2026.
This paper proposes a dynamic search cluster head selection method for resource occupancy protection switching. By integrating multidimensional fitness functions, energy consumption models, and closed‐loop control mechanisms, and combining optimized dynamic search strategies, the optimal cluster head is selected.
