On Robust Colorings of Hamming-Distance Graphs [PDF]

open access: yesThe Electronic Journal of Combinatorics, 2018
$H_q(n,d)$ is defined as the graph with vertex set $\mathbb{Z}_q^n$ and where two vertices are adjacent if their Hamming distance is at least $d$. The chromatic number of these graphs is presented for various sets of parameters $(q,n,d)$. For the $4$-colorings of the graphs $H_2(n,n-1)$ a notion of robustness is introduced. It is based on the tolerance

Unveiling Internet Streaming Services: A Comparison Using Neutrosophic Graphs

open access: yesFuzzy Information and Engineering
This paper investigates the inverse of the maximum result obtained by multiplying two unique graph types known as neutrosophic graphs. The main goal is to comprehend a point’s degree in the opposite situation of a neutrosophic graph’s maximum product ...

Minimal residual ordinal loss hashing with an adaptive optimization mechanism

open access: yesEURASIP Journal on Image and Video Processing, 2020
The binary coding technique has been widely used in approximate nearest neighbors (ANN) search tasks. Traditional hashing algorithms treat binary bits equally, which usually causes an ambiguous ranking.

Object-Level Visual-Text Correlation Graph Hashing for Unsupervised Cross-Modal Retrieval

open access: yesSensors, 2022
The core of cross-modal hashing methods is to map high dimensional features into binary hash codes, which can then efficiently utilize the Hamming distance metric to enhance retrieval efficiency.

Algorithms for the Shortest Path Improvement Problems under Unit Hamming Distance

open access: yesJournal of Applied Mathematics, 2013
In a shortest path improvement problem under unit Hamming distance (denoted by SPIUH), an edge weighted graph with a set of source-terminal pairs is given; we need to modify the lengths of edges by a minimum cost under unit Hamming distance such that the

Accel-Align: a fast sequence mapper and aligner based on the seed–embed–extend method

open access: yesBMC Bioinformatics, 2021
Background Improvements in sequencing technology continue to drive sequencing cost towards $100 per genome. However, mapping sequenced data to a reference genome remains a computationally-intensive task due to the dependence on edit distance for dealing ...

Subdivided graphs as isometric subgraphs of Hamming graphs

open access: yesEuropean Journal of Combinatorics, 2009
It is proven that given G a subdivision of a clique Kn (n > 0), G is isometrically embeddable in a Hamming graph if and only if G is a partial cube or G=Kn. The characterization for subdivided wheels is also obtained.

Hamming dimension of a graph—The case of Sierpiński graphs

open access: yesEuropean Journal of Combinatorics, 2013
The Hamming dimension of a graph G is introduced as the largest dimension of a Hamming graph into which G embeds as an irredundant induced subgraph. An upper bound is proved for the Hamming dimension of Sierpinski graphs S"k^n, k>=3. The Hamming dimension of S"3^n grows as 3^n^-^3.

Visual Understanding of Metabolic Pathways Across Organisms Using Layout in Two and a Half Dimensions

open access: yesJournal of Integrative Bioinformatics, 2004
We propose a method for visualizing a set of related metabolic pathways across organisms using 2 1/2 dimensional graph visualization. Interdependent, twodimensional layouts of each pathway are stacked on top of each other so that biologists get a full ...

Top Position Sensitive Ordinal Relation Preserving Bitwise Weight for Image Retrieval

open access: yesAlgorithms, 2020
In recent years, binary coding methods have become increasingly popular for tasks of searching approximate nearest neighbors (ANNs). High-dimensional data can be quantized into binary codes to give an efficient similarity approximation via a Hamming ...
