A Heuristic for Direct Product Graph Decomposition [PDF]

open access: yes, 2023
In this paper we describe a heuristic for decomposing a directed graph into factors according to the direct product (also known as Kronecker, cardinal or tensor product). Given a directed, unweighted graph G with adjacency matrix Adj(G), our heuristic

Graph and network algorithms [PDF]

open access: yesACM Computing Surveys, 1996
Graphs provide a powerful tool to model objects and relationships among objects. The study of graphs dates back to Euler’s days in the 18th century, when he defined the Konigsberg bridge problem, and since then has been pursued by many researchers.

Graph Algorithm Animation with Grrr [PDF]

open access: yes, 2000
We discuss geometric positioning, highlighting of visited nodes and user defined highlighting that form the algorithm animation facilities in the Grrr graph rewriting programming language. The main purpose of animation was initially for the debugging and

Order Reconfiguration under Width Constraints [PDF]

open access: yes, 2023
In this work, we consider the following order reconfiguration problem: Given a graph G together with linear orders ω and ω′ of the vertices of G, can one transform ω into ω′ by a sequence of swaps of adjacent elements in such a way that, at each time ...

A survey of graph-based algorithms for discovering business processes

open access: yesIJAIN (International Journal of Advances in Intelligent Informatics), 2019
Algorithms of process discovery help analysts to understand business processes and problems in a system by creating a process model based on a log of the system. There are existing algorithms of process discovery, namely graph-based.

Graph Extremities Defined by Search Algorithms

open access: yesAlgorithms, 2010
Graph search algorithms have exploited graph extremities, such as the leaves of a tree and the simplicial vertices of a chordal graph. Recently, several well-known graph search algorithms have been collectively expressed as two generic algorithms called ...

A graph rewriting programming language for graph drawing [PDF]

open access: yes, 1998
This paper describes Grrr, a prototype visual graph drawing tool. Previously there were no visual languages for programming graph drawing algorithms despite the inherently visual nature of the process.

GRAph Parallel Actor Language: A Programming Language for Parallel Graph Algorithms [PDF]

open access: yes, 2013
We introduce a domain-specific language, GRAph Parallel Actor Language, that enables parallel graph algorithms to be written in a natural, high-level form.

Efficient Processing of All Nearest Neighbor Queries in Dynamic Road Networks

open access: yesMathematics, 2021
The increasing trend of GPS-enabled smartphones has led to the tremendous usage of Location-Based Service applications. In the past few years, a significant amount of studies have been conducted to process All nearest neighbor (ANN) queries. An ANN query

Algorithms on evolving graphs [PDF]

open access: yesProceedings of the 3rd Innovations in Theoretical Computer Science Conference, 2012
Motivated by applications that concern graphs that are evolving and massive in nature, we define a new general framework for computing with such graphs. In our framework, the graph changes over time and an algorithm can only track these changes by explicitly probing the graph.
