title: BFS & DFS - Which vertex to start with?
body: <p>I've read pages and pages of information on BFS and DFS algorithms. What none of them say, is which vertex to choose first?</p>
  
  <p>For instance, in this image, do the arrows mean you cannot traverse from c to b, but can traverse from b to c?</p>
