Discrete Mathematics: Graph Theory

Illustrate the basic terminology of graph theory (e.g., vertex, edge, graph, degree of a vertex).
(Content unavailable)
Use graphs to map situations in which the vertices represent objects, and edges represent a particular relationship between objects.
(Content unavailable)
Identify and describe degree and connectedness.
(Content unavailable)
Determine whether a graph is planar or nonplanar.
(Content unavailable)
Analyze the relationship between faces, edges, and vertices using Euler’s formula (𝐹 = 𝐸 – 𝑉 + 2).
(Content unavailable)
Use directed graphs (digraphs) to represent situations with restrictions in traversal possibilities.
(Content unavailable)
Determine when graphs are trees.
(Content unavailable)
Determine whether a graph has an Euler circuit or path, and determine the circuit or path, if it exists.
(Content unavailable)
Determine whether a graph has a Hamilton circuit or path, and determine the circuit or path, if it exists.
(Content unavailable)
Count the number of Hamilton circuits for a complete graph with 𝑛 vertices.
(Content unavailable)
Use an Euler circuit algorithm to solve optimization problems.
(Content unavailable)
Model projects consisting of several subtasks, using a graph.
(Content unavailable)
Use graphs to resolve conflicts that arise in scheduling.
(Content unavailable)
Use graph coloring to determine the chromatic number of a graph.
(Content unavailable)
Recognize algorithms such as nearest neighbor, brute force, and cheapest link as they apply to graphs.
