Chapter 6, Problem 9DQ
Explanation of Solution
Internet History:
- Internet is started in the year 1960s as a way for government researchers to share information.
- In the year 1962, the global network was first proposed by the J.C.R. Licklider of MIT and moved over to the DARPA (Defense Advanced Research Projects Agency) after 1962 he take the responsibility to develop it.
- The theory of packet switching was developed by the Leonard Kleinrock of MIT and later UCLA.
- In the year 1965, Lawrence Roberts of MIT connected a California computer with the Massachusetts computer through dial-up telephone lines.
- The result of this connection is more feasible for wide area networking, but also exposed that the telephone line circuit switching was insufficient.
- Finally the theory of Kleinrock’s packet switching is confirmed...

- You are given a rope of length n meters and scissors that can cut the rope into any two pieces. For simplification, only consider cutting the rope at an integer position by the meter metric. Each cut has a cost associated with it, c(m), which is the cost of cutting the rope at position m. (You can call c(m) at any time to return the cost value.) The goal is to cut the rope into k smaller pieces, minimizing the total cost of cutting. B Provide the pseudo-code of your dynamic programming algorithm f(n,k) that will return the minimum cost of cutting the rope of length n into k pieces. Briefly explain your algorithm.
