  • Fastnet: an R Package for Fast Simulation and Analysis of Large-Scale Social Networks
    JSS Journal of Statistical Software November 2020, Volume 96, Issue 7. doi: 10.18637/jss.v096.i07 fastnet: An R Package for Fast Simulation and Analysis of Large-Scale Social Networks Xu Dong Luis Castro Nazrul Shaikh Tamr Inc. World Bank Cecareus Inc. Abstract Traditional tools and software for social network analysis are seldom scalable and/or fast. This paper provides an overview of an R package called fastnet, a tool for scaling and speeding up the simulation and analysis of large-scale social networks. fastnet uses multi-core processing and sub-graph sampling algorithms to achieve the desired scale-up and speed-up. Simple examples, usages, and comparisons of scale-up and speed-up as compared to other R packages, i.e., igraph and statnet, are presented. Keywords: social network analysis, network simulation, network metrics, multi-core process- ing, sampling. 1. Introduction It has been about twenty years since the introduction of social network analysis (SNA) soft- ware such as Pajek (Batagelj and Mrvar 1998) and UCINET (Borgatti, Everett, and Freeman 2002). Though these software packages are still existent, the last ten years have witnessed a significant change in the needs and aspiration of researchers working in the field. The growth of popular online social networks, such as Facebook, Twitter, LinkedIn, Snapchat, and the availability of data from large systems such as the telecommunication system and the inter- net of things (IoT) has ushered in the need to focus on computational and data management issues associated with SNA. During this period, several Python (Van Rossum et al. 2011) and Java based SNA tools, such as NetworkX (Hagberg, Schult, and Swart 2008) and SNAP (Leskovec and Sosič 2016), and R (R Core Team 2020) packages, such as statnet (Hunter, Handcock, Butts, Goodreau, and Morris 2008; Handcock et al.

  • Network Visualization with Igraph
    Using igraph for Visualisations Dr Jamsheed Shorish The Australian National University [email protected] 15 July 2013 - Beihang University Introduction I igraph is a network analysis and visualisation software package, currently for R and Python. I It can be found at igraph.sourceforge.net. I For our course, we will be using igraph for R . Screenshot from the igraph website, depicting an Erdős - Rényi graph and associated colour-coded components, or clusters. Installing igraph for R I Installation of igraph for R is very simple–the command is: > install.packages( 'igraph ') I You may need to specify a particular directory if e.g. you don’t have privileges to install to the system location for R : > install.packages( 'igraph ', lib='my/ package/location ') I To load the library, use > library( 'igraph ',lib) I or > library( 'igraph ', lib. loc='my/package/ location ') Loading a Dataset I The first thing to do is to get some data! I For consistency I’ll assume that all data is loaded in graphml format. I This can be exported by the Python networkx package. I To load a network dataset from a file, use: > G = read.graph( 'network.graphml ', format ='graphml ') I Confirm that your dataset is recognised by igraph : > G IGRAPHD-W- 560 1257 -- \ + attr: label (v/c), id (v/c), weight (e/n ), id (e/c) Layout of a Graph I To visualise a network well, use the layout function of igraph to specify the layout prior to plotting. I Different networks work best with different layouts–this is more art than science.

  • Constructing 5-Chromatic Unit Distance Graphs Embedded in the Euclidean Plane and Two-Dimensional Spheres
    Constructing 5-chromatic unit distance graphs embedded in the Euclidean plane and two-dimensional spheres V.A. Voronov,∗ A.M. Neopryatnaya,† E.A. Dergachev‡ [email protected] June 24, 2021 Abstract This paper is devoted to the development of algorithms for finding unit distance graphs with chromatic number greater than 4, embedded in a two-dimensional sphere or plane. Such graphs provide a lower bound for the Nelson–Hadwiger problem on the chromatic number of the plane and its generalizations to the case of the sphere. A series of 5-chromatic unit distance graphs on 64513 vertices embedded into the plane is constructed. Unlike previously known examples, these graphs do not contain the Moser spindle as a subgraph. The construction of 5-chromatic graphs embedded in a sphere at two values of the radius is given. Namely, the 5-chromatic unit distance graph on 372 vertices embedded into the circumsphere of an icosahedron with a unit edge length, and the 5-chromatic graph on 972 vertices embedded into the circumsphere of a great icosahedron are constructed. 1 Introduction This paper is devoted to one of the questions related to the Nelson–Hadwiger problem on the chromatic number of the plane [15, 36], namely the development of algorithms that allow constructing new examples of 5-chromatic unit distance graphs embedded in a plane or a sphere, based on a given 4-chromatic unit distance subgraph. The chromatic number of a subset of the Euclidean space X ⊆ Rn is the minimum number of colors needed to color X, so that the points u, v at a unit distance apart are arXiv:2106.11824v2 [math.CO] 23 Jun 2021 colored differently, i.e.

  • Ucod - Simplifying Supply Chain Structures in the Browser
    UCoD - Simplifying Supply Chain Structures in the Browser Alex Trostanovsky and Nikola Cucuk Fig. 1: The Underutilized Constraint Detector. Abstract— Visualizing supply chain networks is difficult but important. Analyzing supply chains as node-link graphs can reveal topological information about the dependencies that exist between parts and the resources those parts depend on. In previous work, we developed a heuristic algorithm that detects underutilized components in a supply chain. In this work, we present UCoD: the Underutilized COnstraint Detector, a tool that highlights the output of this heuristic algorithm, and allows supply chain planners to visualize the structure of their supply chain, and help them identify underutilization and anomalous patterns and trends in their network. UCoD consists of a juxtaposed view of a node-link diagram and an adjacency matrix of the supply chain graph, and a superimposed line chart that allows supply chain planners to inspect time-series of utilization for the nodes in their network. This functionality allows supply chain planners to verify the output of our heuristic algorithm and simplify their product structures.

The complexity of those integrals, in combination with the large number of Feynman diagrams, make the calculations very difficult. Reduction methods proved to be very helpful, lowering the number of integrals that need to be actually calculated. Especially reduction at the integrand level improves the speed and set-up of these calcu- lations. In this article we demonstrate, by counting the numbers of tensor structures and independent coefficients, how to write such relations at the integrand level for one− and two−loop amplitudes. We clarify their connection to the so-called spurious terms at one loop and discuss their structure in the two−loop case. This method is also applicable to higher loops, and the results obtained apply to both planar and non-planar diagrams.
