Notes: Mentions at least 2 specific points from the assigned reading/topic. Utilizes at least 2 resources that are properly cited. Discussion at a graduate level, not just recitation of facts from the article. Length of post is at least 300 words.

Question 3:With regard to graphs,

(1) why is it a good idea to separate the first (entry) node from any looping nodes? and

(2) why is it a good idea to have JUST ONE alternative direction, given an operation? [For instance if X < Y we go from node 3 to node 4 ONLY and no other node].  And,

(3) Is there a better way to do all of this?  A better way to represent logic flow than these types of diagrams (either the manual ones like we used in chapter 6 or the ones we saw from the Node Generator for instance)???
