GraphViz is a collection of tools for manipulating graph structures and generating graph layouts. Graphs can be either directed or undirected. GraphViz offers both graphical and command-line tools. A ...

We present a method to estimate block membership of nodes in a random graph generated by a stochastic blockmodel. We use an embedding procedure motivated by the random dot product graph model, a ...

A real variate is defined for the ordered pairs of nodes in a finite graph. We consider the problem of estimating the total of the variate values from the information provided by a node sample. The ...
