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 ...

Two graphs that are isomorphic. Back in 1979, two scientists wrote a seminal textbook on computational complexity theory, describing how some problems are hard to solve. The known algorithms for ...

These educational materials have been built to serve three purposes: Provide clear, understandable, reference implementations of graph theory concepts and algorithms targeted at people learning these ...

Directed vs Undirected Graphs Another important concept in graph theory is the difference between directed and undirected graphs. The previous two examples have demonstrated undirected graphs. As the ...

In general graphs theory has a wide range of applications in diverse fields. This paper explores different elements involved in graph theory including graph representations using computer systems and ...
