Graphs are everywhere. In discrete mathematics, they are structures that show the connections between points, much like a public transportation network. Mathematicians have long sought to develop ...

Let's first define what exactly the problem is. Take this graph, for instance. For the purposes of this post, the blue circles represent "nodes" or "vertices" and the black lines are "edges" or "node ...

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 ...

There is a growing number of middle-ware products handling navigation of game agents. We are not going to review or even attempt to mention any of them. While they may provide solid solutions for many ...
