HW 7 Grades

Statistics for the most recent returned homework are:

  • Mean: 60
  • Median: 75
  • Standard Deviation: 36

I only have one note to make about the homework papers:

Question 1 required a directed graph with distinct edge costs; many students submitted undirected graphs as counter examples, and many had repeated edge costs.  Although the penalties were relatively small if the ideas behind your counterexample were correct, it’s still important to read every question carefully, and make sure your proofs or counterexamples strictly adhere to the situation described in the question.
