Chapter 6, Problem 6.27E
(Eight Queens: Brute-Force Approaches) In this problem you’ll develop several brute-force approaches to solving the Eight Queens problem introduced in Exercise 6.26.
- Solve the Eight Queens problem, using the random brute-force technique developed in Exercise 6.25.
- Use an exhaustive technique (i.e., try all possible combinations of eight queens on the chessboard).
- Why do you suppose the exhaustive brute-force approach may not be appropriate for solving the Eight Queens problem?
- Compare and contrast the random brute-force and exhaustive brute-force approaches in general.

- Simulate on a vertical time axis (with events labeled with the senders names A-D) the contention period of FOUR equally distanced Ethernet stations that all attempt to transmit at T=0 a minimally sized frame, in the style of the binary Exponential Backoff Algorithm. Assume that time is measured in slot times, and that exactly one slot time is needed to detect a collision (so that if two stations transmit at T=1 and collide, and one of them chooses a backoff time k=0, then that station will transmit again at T=2). Use as coin flip (source of randomness) an ID written in binary. use the bits in order from the least significant to the most significant. If for a given coin throw you need k bits, use the least significant ID bit extracted in the corresponding group of bits, as the least significant bit of the coin thrown.
