Graph Theory History Leonhard Euler - founder The Seven Bridges of Königsberg Cross every Bridge once Change the city into a graph Change the graph into a matrix

Applications Programming Engineering Communications Circuitry Social Networks Shortest Path

Knight’s Tour Hamilton Path A path that visits every vertex on a graph one time Knight’s Tour A path that a knight takes on a n x n or n x m checkerboard to visit every vertex once Setup Create a graph Model graph with a matrix

Purpose Finding new ways to solve for a knight’s tour Figuring out where a knight can arrive with a restricted amount of moves Finding out how many moves a knight needs to get anywhere on the board
