Median and Hybrid Median K-Dimensional Trees

open access: yes, 2022
We consider here two new variants of K-dimensional binary search trees (K-d trees): median K-d trees and hybrid-median K-d trees. These two kinds of trees are designed with the aim to get a tree as balanced as possible. This goal is attained by heuristics that choose for each node of the K-d tree the appropriate coordinate to discriminate.

An adaptive multiphase approach for large unconditional and conditional p-median problems [PDF]

open access: yes, 2014
A multiphase approach that incorporates demand points aggregation, Variable Neighbourhood Search (VNS) and an exact method is proposed for the solution of large-scale unconditional and conditional p-median problems. The method consists of four phases. In

The median function on median graphs and semilattices

open access: yesDiscrete Applied Mathematics, 2000
Let \(\pi = (x_1, x_2, \dots, x_k)\) be a \(k\)-tuple of vertices in a finite connected graph \(G\). A median of \(\pi\) is a vertex \(x\) for which \(\sum^k_{i=1} d(x, x_i)\) is minimum, where \(d\) is a geodesic metric on \(G\). The median function on \(G\) is the function \(M\), defined by \(M(\pi) = \{x |x \text{ is a median of } \pi\}\), whose ...

A Machine-Learning-Based IoT System for Optimizing Nutrient Supply in Commercial Aquaponic Operations

open access: yesSensors, 2022
Nutrient regulation in aquaponic environments has been a topic of research for many years. Most studies have focused on appropriate control of nutrients in an aquaponic set-up, but very little research has been conducted on commercial-scale applications.

Solving Large p-median Problems by a Multistage Hybrid Approach Using Demand Points Aggregation and Variable Neighbourhood Search [PDF]

open access: yes, 2015
A hybridisation of a clustering-based technique and of a variable neighbourhood search (VNS) is designed to solve large-scale p-median problems. The approach is based on a multi-stage methodology where learning from previous stages is taken into ...
