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!

I wanted to bring up my paper on the Seymour Second Neighborhood Conjecture. The #coordinatePlane and proof use a well ordering which used BFS and a minimum counterexample. #maths #math #graphtheory #mathisbeautiful #algorithm alphaxiv.org/abs/2501.00614
A nested set of round-cornered rectangles. Very similar to a Venn diagram
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 - […]

Teeny Tiny Soma Cube in a bottle. 6mm unit cube. 7 color version is on the way from a 3D printer in Winnipeg.
80 of them for about $1USD each. I'm so overwhelmed by the teeny tininess and affordability I can barely sit still in my chair.

How I approached the Seymour Second Neighborhood Conjecture. Standard visualizations lead to high crossing numbers, leading to difficulty in recognizing patterns. By utilizing a BFS layout, and a minimal criminal, patterns emerged. #math #graphtheory www.alphaxiv.org/abs/2501.00614

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
SPEND THE HOUR:

a 6x6 grid of order 5 undirected graphs. each graph has vertices marked by points, and edges are lines. the graphs are ordered by number of edges, from 0 to 10 (fully connected). plotted on a green CRT analog X Y display, so background is black.
Enumerating graphs is fun. This code is meant to enumerate graphs up to isomorphism for each number of edges, in order 5. The population increases dramatically by order!
There's an international contest too

Screenshot of PDF: Efficient Planarity Testing, paper by Robert Tarjan and John Hopcroft. October 1974. Image shows some elegant metal typesetting and two diagrams Figure 3 (a) and (b); (a) being "A graph G to be tested for planarity;" and (b) being "a palm tree P generated from G. Upward, solid edges are tree arcs. Downward, dotted edges are fronds. Vertices are numbered in search order."
Good things have been done. You can download previously paywalled ACM articles.
