http://math.youngzones.org/Konigsberg.html • Graph Theory: • Description of a Point: A point is a NODE of a network • Description of a Line: A line is an arc connecting either two nodes or a node to itself
Even or Odd Node • Even Node: has an even number of arcs from a node • Odd Node: has an odd number of arcs from a node
Def: Traversable • A network is said to be traversable if you can trace the entire network without repeating any section • Note: a network is traversable if it has two or less odd nodes
