Graph Theory
A study that has helped us build the internet.
Graph Theory
Used to represent networks of communication, data organization, computational devices, the flow of computation, etc.

What is a set of nodes of vertices linked by edges?
Graph
What are the main points of a graph?
Nodes/Vertices
What do you call the arcs or branches of a grapah?
Edges
What term is used when attributes are given to the vertices and/or edges?
Network
What do you call a graph whose edges are not all bidirectional?
Directed/Diagraph
What do you call a graph where no edge is bidirectional?
Undirected
A sequence of distinct edges that join two nodes through other nodes.
Path
The number of edges in a path.
Length of a Path
A path that begins and ends at the same vertex.
Circuit
What do you call it if a path connects a node to itself?
Cycle
Cycles with length one.
Loops
What do you call it if two distinct nodes are linked by at least one path?
Connected
A graph that has no loops and has no edges that repeat.
Simple Graph
A connected graph that has no cycles.
Tree
A graph where it is possible to find a route that starts from one vertex, traverses every edge exactly once, and ends at the starting veretex.
Euler Graphs
Route of Euler Graphs that are not unique.
Eulerian trail.
A graph wherein it is possible to find a route that starts with one vertex, visits every vertex exactly once along incident edges, and ends at the starting vertex.
Hamiltonian Graphs
Route of Hamiltonian Graphs.
Hamiltonian Cycle
