KCachegrind : powerful tool to generate and analyze call graphs based on data generated by callgrind; Mac OS X Activity Monitor : Apple GUI process monitor Activity Monitor has a built-in call graph generator that can sample processes and return a call graph. This function is only available in Mac OS X Leopard
GNU Octave is a numerical computation program; effectively a MATLAB clone. It uses gnuplot extensively (though also offers interfaces to Grace and other graphing software). The commands are plot (2D) and splot (surface plot). A graph of the envelope of a wave in GNU octave and gnuplot
Watts–Strogatz small-world model generated by igraph and visualized by Cytoscape 2.5. 100 nodes. The Watts–Strogatz model is a random graph generation model that produces graphs with small-world properties, including short average path lengths and high clustering.
There are functions for which the graph size is always exponential—independent of variable ordering. This holds e.g. for the multiplication function. [ 1 ] In fact, the function computing the middle bit of the product of two n {\displaystyle n} -bit numbers does not have an OBDD smaller than 2 ⌊ n / 2 ⌋ / 61 − 4 {\displaystyle 2 ...
In mathematics, a Cayley graph, also known as a Cayley color graph, Cayley diagram, group diagram, or color group, [1] is a graph that encodes the abstract structure of a group. Its definition is suggested by Cayley's theorem (named after Arthur Cayley ), and uses a specified set of generators for the group.
For a simple graph with vertex set U = {u 1, …, u n}, the adjacency matrix is a square n × n matrix A such that its element A ij is 1 when there is an edge from vertex u i to vertex u j, and 0 when there is no edge. [1]
Kronecker graphs are a construction for generating graphs for modeling systems. The method constructs a sequence of graphs from a small base graph by iterating the Kronecker product. [1] A variety of generalizations of Kronecker graphs exist. [2] The Graph500 benchmark for supercomputers is based on the use of a stochastic version of Kronecker ...
A graph generated by the binomial model of Erdős and Rényi (p = 0.01) In the (,) model, a graph is chosen uniformly at random from the collection of all graphs which have nodes and edges. The nodes are considered to be labeled, meaning that graphs obtained from each other by permuting the vertices are considered to be distinct.
