A mathematical graph, with 3 nodes, and one 3-ended edge, with one start and two ends - a hyperedge.

This image is of a simulation of a simple directed #hypergraph , but using an n-ary line rather than a set for the #hyperedge

I have written a working #graphTheory editor for binary edges, where nodes are extended to sets (a #Higraph) , and am contemplating […]

Publication: Optimized topology control for large-scale IoT networks using graph-based localization Imagine a city-wide network of sensors trying to send data back to gateways, but each sensor has limited battery power and the wireless links are often weak or uncertain. This research shows how the n...

A recent publication by Walton Institute's Dr Indrakshi Dey, and Dr Nicola Marchetti from Trinity College Dublin explores a novel approach to topology control in large-scale IoT environments using graph-based localization.

Figure 33 from chapter "The Mystery of the Heawood Conjecture" Figure shows a two-dimensional path with inscrutable notation; it wanders from a node 0 downwards then veers right, then down, then left, then down, right, down, left, down, and continues left with an arrowhead. Nodes are labelled horizontally 0 through 5. Rows are labelled 6 (tilde under), 4 (tilde under), 2, 1, 3. from Graph Theory and its Applications Publication No. 24 of the Mathematics Research Center United States Army The University of Wisconsin Edited by Bernard Harris

A computer drawn higraph. A number of rectangular sets are connected by smoothly curving edges.

A #Higraph milestone: Blobs (nodes as sets) now work! Grab a 'parent' blob, and all the children move. Edges connect anywhere on the blob, and default to be orthogonal to the point of contact. graphML read and write working.

Now on to proper hyperedges!

Hi #Mathstodon - a #GraphTheory question:
Given the following visual set containment, I can obtain the total containment of every item as a list (text on the left). This intuitively seems sufficient information to derive the containment graph (almost a tree - […]

This is an extremely rewarding video, and as Prof. Knuth explains at the start, chosen to be accessible to an undergrad audience.

It's a tiny illustration Knuth's astonishingly thorough, penetrating yet playful career in #math and #computerscience
