Project description

PyRGG: Python Random Graph Generator

Overview

PyRGG is a user-friendly synthetic random graph generator that is written in Python and supports multiple graph file formats, such as DIMACS-Graph files. It can generate graphs of various sizes and is specifically designed to create input files for a wide range of graph-based research applications, including testing, benchmarking, and performance analysis of graph processing frameworks. PyRGG is aimed at computer scientists who are studying graph algorithms and graph processing frameworks.

Installation

PyPI

Check Python Packaging User Guide
pip install pyrgg==1.5

Source Code

Download Version 1.5 or Latest Source
pip install .

Conda

Check Conda Managing Package
conda install -c sepandhaghighi pyrgg

Exe Version (Only Windows)

Download Exe-Version 1.5
Run PYRGG-1.5.exe

System Requirements

Pyrgg will likely run on a modern dual core PC. Typical configuration is:

Dual Core CPU (2.0 Ghz+)
4GB of RAM

Note that it may run on lower end equipment though good performance is not guaranteed.

Usage

Open CMD (Windows) or Terminal (Linux)
Run pyrgg or python -m pyrgg (or run PYRGG.exe)
Enter data

Engines

Max Edge Number	The maximum number of edges connected to each vertex
Weighted / Unweighted	Specifies whether the graph is weighted or unweighted
Min Weight	The minimum weight of the edges (if weighted)
Max Weight	The maximum weight of the edges (if weighted)
Signed / Unsigned	Specifies whether the edge weights are signed or unsigned
Directed / Undirected	Specifies whether the graph is directed or undirected
Self Loop / No Self Loop	Specifies whether self-loop is allowed or not
Simple / Multigraph	Specifies whether the graph is a simple graph or a multigraph
