In 1950 Edward Nelson, then a student at the University of Chicago, asked the kind of deceptively simple question that can give mathematicians fits for decades. Imagine, he said, a graph — a ...

From here graph theory got expanded and generalized into ... The weight assigned to each node is the Euclidian distance, allowing the algorithm to calculate the distance of any newly discovered ...

So far this year, Quanta has chronicled three major advances in Ramsey theory, the study of how to avoid creating ... If you found a 45-node graph without five nodes that were all connected and ...

Graph theory has a lot to say about how phenomena can grow, such as the spread of infectious diseases. There are different graphs, or networks, of relations, and they can affect things such as the ...

Distance-time graphs show how the distance travelled by a moving object changes with time. These graphs also show if the object is moving at a constant speed or accelerating, going back to the ...

D3 enables you to (fairly) easily create animated node and edge graphs from mathematical graph theory. Conceptually, Alexander's resolutions of form and context are the sorts of problems that ...
