Finding the shortest path between two points is one of the most fundamental problems in computer science and mathematics. Graph theory provides an efficient way to model real-world systems such as ...

You can create a release to package software, along with release notes and links to binary files, for other people to use. Learn more about releases in our docs.

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 ...

Here is a problem I'm working on. Say you have a weighted, directed graph with n vertices and m edges, and you want to find the shortest path from s to all other vertices, *but* you can only use some ...

Graph algorithms constitute a pivotal component of modern computational science, underpinning diverse applications ranging from transportation optimisation and telecommunications to social network ...
