Key terms from CSCI 3110 Lecture 1a
Term | Definition |
---|---|
Eulerian Cycle | A cycle of a graph that contains each edge exactly once and ends on the same vertex |
Eulerian Graph | A graph which contains a Eulerian cycle. |
Finite Eulerian Graph | A graph which is connected and all vertices' degrees are even |
Finite Directed Eulerian Graph | When the underlying directed graph is Eulerian, and each in-degree and out-degree are equal |
In-Degree | The number of head ends coming into a vertex |
Out-Degree | The number of tail ends coming out of a vertex |
Eulerian path | A path in a finite graph that visits every edge exactly once, allowing for revisiting vertices |
Hamiltonian Cycle | A cycle of a graph that visits each vertex exactly once |
Planar Separator Theorm | A theorem that states that any planar graph can be split into smaller pieces by removing a small number of vertices |
Edge-Disjoint Cycles | Two cycles are edge-disjoint when they have no edges in common |
