    vizceral

    vizceral

    WebGL visualization for displaying animated traffic graphs

    vizceral is a component for displaying traffic data on a webgl canvas. If a graph of nodes and edges with data about traffic volume is provided, it will render a traffic graph animating the connection volume between nodes. This component can take multiple traffic graphs and will generate a 'global' graph showing all incoming traffic into each of the 'regions', with support for cross-region traffic. There are three levels of information, global, regional, and service-level, with clicking or double-clicking on a node bringing you one level deeper. ...

    The min cost is a program which is going to find the minimum cost or path of any given numbers. if you have a certain set of numbers this program is going to calculate the optimized cost for that set. Similarly, the program can perform Dijkstra's algorithm which is an algorithm for finding the shortest paths between nodes in a graph by simply insert the node distance in the input file and output the shortest path in output file. The program was written in C++ using a main algorithm of a heap sorting. In this program, specifically users the codes for minimum heap since the purpose of the program is to find the minimum cost or path.

    Brainstorm Network

    Software to organize a brainstorm as a complex network.

    This project aims to organize a brainstorm or a bibliographic revision in a network (graph). With this organization the users are able to visualize the main points of the brainstorm (the hubs in the network). Moreover, they can access the information through the rede, interactively, clicking on the edges or nodes! All information is associated with a reference list (imported from a bibtex file). This project uses Python, Web2py, MariaDB and VIS.js (D3.js).

    We consider a problem of finding maximum weight subgraphs (MWS) that satisfy hard constraints in a weighted graph. The constraints specify the graph nodes that must belong to the solution as well as mutual exclusions of graph nodes, i.e., pairs of nodes that cannot belong to the same solution. Our main contribution is a novel inference approach for solving this problem in a sequential monte carlo (SMC) sampling framework. Usually in an SMC framework there is a natural ordering of the states of the samples. ...

    ThunderstormDistributor

    Distribute jobs to compute nodes on dynamic clusters

    ThunderstormDistributor is a queuing system that distributes jobs and computational workload across dynamic clusters in the cloud. It manages the assignment of jobs to maximize CPU and memory usage and prevent oversubscription of compute nodes. It also performs advanced statistics collection on individual compute nodes and jobs to graph the distribution of disk, network, CPU, and memory usage over time, which facilitates the advanced optimization and tuning of computational workflows.

    GraphVisu

    GraphVisu

    A graph visualisation and exploration program

    GraphVisu is a visualisation and exploration software for oriented graphs. It automatically and dynamically moves the graph nodes to ensure an efficient visualisation. In particular, it displays the hierarchy between nodes with mainly incoming links and nodes with mainly outcoming links. "Strongly connected components", that is parts of the graph without clear hierarchy, are also detected and displayed. GraphVisu has been originally developped to visualise the dependance relations within XSD files - a graph construction program for this specific case is available.

    Reco4j is a graph-based recommendation engine, this is the neo4j impl

    Reco4j is an open source project aims at developing a recommendation framework based on graph data sources. We choose graph databases for several reasons. They are NoSQL databases, so "schemaless". This means that it is possible to extend the basic data structure with intermediate information, i.e. similarity value between item and so on. Moreover, since every information is expressed with properties, nodes and relations, the recommendation process can be customized to work on every graph. ...

    Diffusive

    Task-oriented distributed computing framework

    ...In diffusive programming, any method can be marked for distribution, regardless of its signature. And marking a method is necessary and sufficient for its execution to be distributed. Distribution of tasks occurs through a network of nodes that can accept tasks and execute them, or forward them on. Nodes executing a task, load the required resources as needed, and cache them. The topology of the network of nodes can be anything that can be represented as a directed graph. Topologies can be tailored to solve specific problems. Diffusive is a Java refer- ence implementation of the six principles that define diffusive programming.

    python dagger

    File dependency graph evaluator in pure python.

    Dagger evaluates file dependencies in a directed-acyclic-graph (DAG) like GNU make, but timestamps or hashes can be used on a per-file basis when evaluating which file nodes are up to date or stale. Use fast timestamp comparisons on large files when hashing is too slow, and hashing on small files. When hashing is used, it's stored in either a text file or sqlite database (in-memory at runtime is optional).

    graphseg

    Library for segmenting a graph, images in particular.

    Primarily this library was developed for producing a set of super-pixels from an image (i.e. an over-segmentation). The segmentation is produced by running multiple instances of Dijkstra's Algorithm from a set of seed points; those nodes which belong to a given Dijkstra cloud form a segment (so the number of segments is fixed and determined at the beginning of the algorithm). The goal is to add code that moves from the over-segmentation to a more useful segmentation. The library includes code specifically for the purpose of image segmentation but there are several components useful for general graph segmentation.

    TikZ-dependency

    TikZ-dependency

    A LaTeX library to draw all sorts of dependency trees and graphs

    ...The package has a very easy to learn, high level interface that can be used to draw simple dependency trees, complex non projective graphs, bubble parses, and in general any kind of graph which is based on a sequence of nodes and edges among these. It is based on PGF/TikZ and it can be used either with latex or pdflatex. It comes with a very comprehensive documentation that will get you started in 10 minutes, even without any prior knowledge of TikZ. It also provides a lot of styling facilities, to let you personalize the look and feel of the graphs at your liking.
