A Performance Study of Some Approximation Algorithms for Computing a Small Dominating Set in a Graph

open access: yesAlgorithms, 2020
We implement and test the performances of several approximation algorithms for computing the minimum dominating set of a graph. These algorithms are the standard greedy algorithm, the recent Linear programming (LP) rounding algorithms and a hybrid ...

A local search algorithm with hybrid strategies for the maximum weighted quasi‐clique problem

open access: yesElectronics Letters, 2023
Identifying cohesive subgraphs is an important topic in graph theory and complex network analysis. The quasi‐clique, as a generalization of clique, can be used to identify the functional and structural properties of various networks.

Survey of 8 UAV Set-Covering Algorithms for Terrain Photogrammetry

open access: yesRemote Sensing, 2020
Remote sensing with unmanned aerial vehicles (UAVs) facilitates photogrammetry for environmental and infrastructural monitoring. Models are created with less computational cost by reducing the number of photos required.

A Greedy Hypercube-Labeling Algorithm [PDF]

open access: yesThe Computer Journal, 1992
Due to its attractive topological properties, the hypercube multiprocessor has emerged as one of the architectures of choice when it comes to implementing a large number of computational problems. In many such applications, Gray-code labelings of the hypercube are a crucial prerequisite for obtaining efficient algorithms.

Improved Performance of Mean Greedy Algorithm for Chunk Allocation in SC-FDMA Uplink Systems using Joint-User and Chunk-Based Allocation

open access: yesJournal of ICT Research and Applications, 2014
In this paper, the problem of subcarrier allocation on chunk-by-chunk basis in SC-FDMA uplink systems is investigated. Improved mean enhanced greedy algorithms are proposed for performing joint-user and chunk-based allocation at each transmission time ...

Greedy Algorithms for Optimal Distribution Approximation

open access: yesEntropy, 2016
The approximation of a discrete probability distribution t by an M-type distribution p is considered. The approximation error is measured by the informational divergence D ( t ∥ p ) , which is an appropriate measure, e.g., in the ...

Sharp sufficient condition for the convergence of greedy expansions with errors in coefficient computation

open access: yesDemonstratio Mathematica, 2022
Generalized approximate weak greedy algorithms (gAWGAs) were introduced by Galatenko and Livshits as a generalization of approximate weak greedy algorithms, which, in turn, generalize weak greedy algorithm and thus pure greedy algorithm.
