What is vertex colouring?
Focus on adjacent vertices.
Can you define edge chromatic number?
Think about edges sharing vertices.
What is the minimum number of colours required in a graph with 8 vertices where the maximum degree is 3?
Think about the maximum degree.
Vertex chromatic number is denoted by which symbol?
It's a Greek letter.
Given a graph with 10 vertices where the maximum degree is 5, explain the implications for edge chromatic number. How would you utilize Δ(G)?
Examine the implications based on vertex edges.
Illustrate a scenario in real life where graph colouring is applied and how you would determine chromatic numbers.
Think about how to model overlaps as connections in a graph.
