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.

Combined with algorithms that can handle such graphs it’s a great way to not only make the basic structure of a network clear, but also to model structures and systems.

Now imagine that you want to insert a new edge connecting two nodes in a planar graph, say nodes 1 and 6 in the example below. To do so, you’re going to perform a series of flips. From the starting ...

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 ...

Google's Knowledge Graph algorithm currently updates every 2 to 3 weeks, affecting 60-80% of entities. Here's what SEOs need to know.

The Knowledge Graph just switched gear (perhaps 5 gears!). Please do consider the following examples. Not everyone is a winner. Freshness / Citation Recency ...

Then, it runs the graph algorithm on that small graph, with the algorithm treating the small graph as a portion of a larger, synthetic graph that does not exist. This method, the KAIST researchers ...
