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

The new algorithm also has to work through too many steps for most real-world applications, where the relevant graphs are usually simple enough to check with brute-force methods. But for Holm and ...

Although simple route planning is not as daunting as TSP, there are some similarities, in that it involves a weighted, undirected graph, requiring the algorithm to take into account the cost of ...

What’s more, the new approach uses decades-old mathematical techniques, eschewing more sophisticated methods that have dominated modern graph theory research. “I just couldn’t believe such a simple ...
