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 ...

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 ...

(Feel free to substitute air high-fives if you prefer a little more social distance.) Let’s assume it’s you and ... The dilemma you face exemplifies a simple but profound idea in graph theory, a field ...

Mathematicians have long sought to develop algorithms that can compare any two graphs. In practice, many algorithms always ...

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 ...
