In algorithms, as in life, negativity can be a drag. Consider the problem of finding the shortest path between two points on a graph — a network of nodes connected by links, or edges. Often, these ...

Refining with colors Mathematicians have developed various strategies to compare graphs. Since the 1970s, algorithms have been able to test graph isomorphism, but in exponential time.

Another noteworthy development is a distributed algorithm for computing the weighted girth, which is the length of the minimum-weight cycle in a graph [2]. By adopting a randomised approach and ...
