### Sage 9.3 Reference Manual: Graph Theory - SageMat

• A dictionary of dictionaries: sage: g = DiGraph( {0: {1: 'x', 2: 'z', 3: 'a'}, 2: {5: 'out'}}); g Digraph on 5 vertices. The labels ('x', 'z', 'a', 'out') are labels for edges. For example, 'out' is the label for the edge from 2 to 5. Labels can be used as weights, if all the labels share some common parent
• sage: g = digraphs.Circuit(15) To get a circulant graph on 10 vertices in which a vertex i has i + 2 and i + 3 as outneighbors: sage: p = digraphs.Circulant(10, [2,3]) More interestingly, one can get the list of all digraphs that Sage knows how to build by typing digraphs. in Sage and then hitting tab
• This is an internal module of Sage. All features implemented here are made available to end-users through the constructors of Graph and DiGraph. Note that because they are called by the constructors of Graph and DiGraph, most of these functions modify a graph inplace. Fill G with the data of an adjacency matrix
• G = digraphs.RandomDirectedGN(5) G.plot(vertex_size=200, layout='circular') According to the documentation for plot, however, edge_size is not a valid parameter. You can try looking through the documentation of NetworkX for parameters to control the edge style (arrows and such) and pass these to Sage's graph plot function via the edge_style paramete
• A digraph or directed graph is a set of vertices connected by oriented edges. For more information, see the Wikipedia article on digraphs. One can very easily create a directed graph in Sage by typing

Based on code from Alasdair McAndrew at trac.sagemath.org/ticket/8559. A playfair cipher is a special type of substitution cipher in which the plaintext is broken up into two-letter digraphs with some restrictions. Those digraphs are encrypted using a Polybius square, (i.e. a 5x5 grid in which each letter of the alphabet is its own entry with the exception of ij which are placed together). The positions of the letters in the digraph determine how the digraph is encrypted :meth:~DiGraph.topological_sort_generator | Returns a list of all topological sorts of the digraph if it is acyclic :meth:~DiGraph.topological_sort | Returns a topological sort of the digraph if it is acyclic **Hard stuff:**. csv-table:: :class: contentstable :widths: 30, 70 :delim: | :meth:~DiGraph.feedback_edge_set | Computes the minimum feedback edge (arc) set of a digraph. - # We build a copy of the current Digraph removing loops and edges - # coming in sources - # We give to every edge a label corresponding to its index in the list - # of edges of the current digraph - D = DiGraph(multiedges=True, loops=True) - list_edges = self.edges() - depth = self.order() - 1 - # Adding edges in D with label corresponding to index of that edge in - # self.edges() - for i,(u, v, _) in enumerate(list_edges): - if u != v and v != source: - D.add_edge(u, v, (i,)) - list.

in Graph and DiGraph, data structures based on an adjacency list implemented as a node-centric dictionary of dictionaries. The dictionary contains keys corresponding to the nodes and the values are dictionaries of neighboring node keys with the value None (the Python None type). This allows fast addition, deletion and lookup of nodes and neighbors in large graphs The XGraph and XDiGraph. I have implemented all your comments.

Adjacency Matrix. In graph theory, an adjacency matrix is nothing but a square matrix utilised to describe a finite graph. The components of the matrix express whether the pairs of a finite set of vertices (also called nodes) are adjacent in the graph or not.

It is shown that the summatory function of a regular sequence can asymptotically be decomposed as a finite sum of periodic fluctuations multiplied by a scaling factor. Each of these terms corresponds to an eigenvalue of the sum of matrices of a linear representation of the sequence; only the.
