-  Announcements:
	
	 
	-  Our quiz this week will cover chapter 7 (graph algorithms)
		
		 
		-  Euler paths and Hamiltonian Circuits
		
-  Shortest path and Minimal spanning trees
		
-  Graph traversal (depth-first, breadth-first)
		
 
	 
-  How are 
		your projects coming?
	
 
 
-  Today:
	
	 
	-  Last time: We finished
		Section
		7.3: Shortest Path and Minimal Spanning Tree, and
		started Section
		7.4 (depth-first and breadth-first); I want to look at one
		more example from the graph traversal
		handout for 7.4 before moving on into chapter 8. 
		
	 
-  We examined five different algorithms last time: 
		
		-  Floyd's (all shortest paths)
		
-  Prim's
		
-  Kruskal's
		
-  Depth-first traversal of graphs
		
-  Breadth-first traversal of graphs
		
 
-  Then we had a quiz:
		
		 
		-  Key
		
-  There was a little confusion about the "main connective"
		-- order of operations. The first difference is the root of the
		expression tree.
		
-  I didn't hear any singing on Problem 2 -- maybe that would
		have helped? 
		
-  Missing a lot of floor functions: \(\lfloor \log_2(10)
		\rfloor +1 = 4\). 
		
 
-  Today's new thing is Section 8.1: Boolean Algebras
