Assertion made in lecture 3:
 
* "The base of a logarithm does not matter asymptotically"
 
    * So does that mean that given a set of log functions with different bases, we cannot say that one grows faster than the other?

Newsgroup

On the news.purdue.edu server: purdue.class.ece608

One way to access: SSH to a server at Purdue (ie expert.ics.purdue.edu) and type "lynx news.purdue.edu/purdue.class.ece608"

On Ubuntu, you can use the "Pan" newsreader.

  • "sudo apt-get install pan"
  • Set "news.purdue.edu" as the server. You do not need to enter login information.
  • Type "purdue.class.ece608" in the box in the upper-left of the screen.
  • After a delay (half a minute?) the newsgroup will appear in the left pane. You can right click the group to "subscribe".

4-4

Attempted solution for 4-4 part (d): $ T(n) = 3T(n/3+5)+n/2 $

We use the iteration method. Start with recursion tree:

  • Root node: $ \frac{n}{2} $
  • First level: $ 3\frac{\frac{n}{3}+5}{2} $
  • Second level: $ 9\frac{\frac{n}{3}+5}{4} $
  • ith level: $ \left(\frac{3}{2}\right)^i\left(\frac{n}{3}+5\right) $

$ \left(\frac{n}{3}+5\right)\sum{\left(\frac{3}{2}\right)^i} $
