Bilevel large neighborhood search for the electric autonomous dial-a-ride problem

Transportation Research Interdisciplinary Perspectives, 2023
The electric autonomous dial-a-ride problem (E-ADARP) represents a challenging and practically relevant extension of the dial-a-ride problem, which takes electric vehicle charging into account. It introduces battery constraints and the option to recharge

Vertices with the second neighborhood property in Eulerian digraphs [PDF]

Opuscula Mathematica, 2019
The Second Neighborhood Conjecture states that every simple digraph has a vertex whose second out-neighborhood is at least as large as its first out-neighborhood, i.e. a vertex with the Second Neighborhood Property.

Split-merge:using exponential neighborhood search for scheduling a batching machine [PDF]

, 2015
We address the problem of scheduling a single batching machine to minimize the maximum lateness with a constraint restricting the batch size. A solution for this NP-hard problem is defined by a selection of jobs for each batch and an ordering of those ...

A variable neighborhood search with an effective local search for uncapacitated multilevel lot-sizing problems [PDF]

, 2014
In this study, we improved the variable neighborhood search (VNS) algorithm for solving uncapacitated multilevel lot-sizing (MLLS) problems. The improvement is two-fold.

An adaptive neutrosophic large neighborhood search and its application [PDF]

Neutrosophic Sets and Systems
An adaptive large neighborhood search (ALNS) lacks a clear measure for assessing the improvement degree in the new solution, which causes fuzziness and uncertainty in the operator score.

Neighborhood greenspace and health in a large urban center [PDF]

Scientific Reports, 2015
Abstract Studies have shown that natural environments can enhance health and here we build upon that work by examining the associations between comprehensive greenspace metrics and health. We focused on a large urban population center (Toronto, Canada) and related the two domains by combining high-resolution satellite imagery and ...

Neighborhood scheme selection for classification with SCRD method

Lietuvos Matematikos Rinkinys, 2015
When using Spatial Correlation Rule with Distance (SCRD) the selection of the neighborhood scheme influences classification accuracy. Spatial dependency in different situations remains at various distances, so, according to this, in applications it is ...

Spatial predictive properties of built environment characteristics assessed by drop-and-spin virtual neighborhood auditing

International Journal of Health Geographics, 2020
Background Virtual neighborhood audits have been used to visually assess characteristics of the built environment for health research. Few studies have investigated spatial predictive properties of audit item responses patterns, which are important for ...

ASSESSING NEIGHBORHOOD DISORDER: VALIDATION OF A THREE-FACTOR OBSERVATIONAL SCALE

European Journal of Psychology Applied to Legal Context, 2015
This study presents data on the development and preliminary validation of an observational scale assessing neighborhood disorder. Independent observations by trained raters of neighborhood disorder were conducted in 552 census block groups in the city of
