Infrastructure expansion, tourism and electoral outcomes

Economica, EarlyView.
Abstract This paper examines the electoral impact of economic growth through increased foreign tourism using data from Croatia. To identify causal effects, the paper applies an instrumental variable strategy, which uses variation in the ruggedness of the local terrain to estimate the network of least‐cost paths.

Multi‐objective maritime vessel routing with safety considerations

International Transactions in Operational Research, EarlyView.
Abstract The routing of maritime vessels is a challenging optimization problem that involves finding an adequate balance between conflicting and multiple objectives. This paper proposes a methodology based on inverse optimization to find appropriate objective weights that account for conflicting objectives. To formulate the inverse optimization problem,

Study on Near-Optimal Path Finding Strategies in a Road Network

Journal of Algorithms & Computational Technology, 2008
In this paper we analyze the existing defects of hierarchical and nonhierarchical path finding algorithm respectively in detail and present a hierarchical path finding algorithm based on the heuristic directing search approach which is used for promoting

Half-Duplex Routing is NP-hard

, 2017
Routing is a widespread approach to transfer information from a source node to a destination node in many deployed wireless ad-hoc networks. Today's implemented routing algorithms seek to efficiently find the path/route with the largest Full-Duplex (FD ...

How Context Shapes Person‐Centred Fundamental Care Through Nurse–Patient Relationships: Validation of the FoC Intelligence Modelling Tool and Predictive Pathway Analysis

Journal of Advanced Nursing, EarlyView.
ABSTRACT Background The Fundamentals of Care (FoC) Framework emphasises that care quality depends not only on clinical tasks but also on interpersonal relationships and the organisational context in which care is delivered. Although patient‐reported outcome and experience measures (PROMs and PREMs) have gained relevance in capturing these aspects ...

Smart selective navigator (SSN): enhancing urban winter road maintenance through optimized arc routing with hard turn restrictions

International Transactions in Operational Research, Volume 33, Issue 5, Page 3580-3597, September 2026.
Abstract This paper introduces a novel heuristic method, the smart selective navigator (SSN), for addressing arc routing problems (ARPs) with a focus on integrating hard turn restrictions in urban winter operations. Addressing a significant gap in existing ARP methodologies, SSN seamlessly incorporates common side constraints, such as vehicle ...

Landmark Guided Probabilistic Roadmap Queries

, 2017
A landmark based heuristic is investigated for reducing query phase run-time of the probabilistic roadmap (\PRM) motion planning method. The heuristic is generated by storing minimum spanning trees from a small number of vertices within the \PRM graph ...

Integrated routing of heavy electrical and diesel trucks in forest transports

International Transactions in Operational Research, Volume 33, Issue 5, Page 3088-3109, September 2026.
Abstract Fossil‐free forestry transports are important to reach climate goals. In Sweden, road transports account for around 50% of the industry's CO2 emissions and almost 20% of the road freight volumes. Previous studies have shown that electrification is a cost‐effective way for carbon abatement, while at the same time the requirements for ...

An Exact Method for Reliable Shortest Path Problems With Correlation

Networks, Volume 87, Issue 4, Page 372-389, June 2026.
ABSTRACT Shortest path problems often arise in contexts where travel times are uncertain. In these settings, reliable paths are often valued more than paths with lower expected travel times. This has led to several variants of reliable shortest path problems (RSPP) that handle travel time reliability differently. We propose an algorithmic framework for
