Chapter 2.5, Problem 12MS
Using your code. Given the coding scheme you devised in Mindscape 11, show how a friend would encode “HI” (as in our discussion, use 01 for A, 02 for B,...,26 for Z to convert the letters to numbers). Now decode the coded message. Did you return to your original HI?
The following list of random information may be useful in the subsequent three Mindscapes:

When a tennis player serves, he gets two chances to serve in bounds. If he fails to do so twice, he loses the point. If he
attempts to serve an ace, he serves in bounds with probability 3/8.If he serves a lob, he serves in bounds with probability
7/8. If he serves an ace in bounds, he wins the point with probability 2/3. With an in-bounds lob, he wins the point with
probability 1/3. If the cost is '+1' for each point lost and '-1' for each point won, the problem is to determine the optimal
serving strategy to minimize the (long-run)expected average cost per point. (Hint: Let state 0 denote point over,two
serves to go on next point; and let state 1 denote one serve left.
(1). Formulate this problem as a Markov decision process by identifying the states and decisions and then finding the
Cik.
(2). Draw the corresponding state action diagram.
(3). List all possible (stationary deterministic) policies.
(4). For each policy, find the transition matrix and write an expression for the…
During each time period, a potential customer arrives at a restaurant with probability 1/2. If there are already two people
at the restaurant (including the one being served), the potential customer leaves the restaurant immediately and never
returns. However, if there is one person or less, he enters the restaurant and becomes an actual customer. The manager
has two types of service configurations available. At the beginning of each period, a decision must be made on which
configuration to use. If she uses her "slow" configuration at a cost of $3 and any customers are present during the period,
one customer will be served and leave with probability 3/5. If she uses her "fast" configuration at a cost of $9 and any
customers are present during the period, one customer will be served and leave with probability 4/5. The probability of
more than one customer arriving or more than one customer being served in a period is zero. A profit of $50 is earned
when a customer is served. The manager…
Every Saturday night a man plays poker at his home with the same group of friends. If he provides refreshments for the
group (at an expected cost of $14) on any given Saturday night, the group will begin the following Saturday night in a
good mood with probability 7/8 and in a bad mood with probability 1/8. However, if he fail to provide refreshments, the
group will begin the following Saturday night in a good mood with probability 1/8 and in a bad mood with probability
7/8 regardless of their mood this Saturday. Furthermore, if the group begins the night in a bad mood and then he fails
to provide refreshments, the group will gang up on him so that he incurs expected poker losses of $75. Under other
circumstances he averages no gain or loss on his poker play. The man wishes to find the policy regarding when to
provide refreshments that will minimize his (long-run) expected average cost per week.

- This year Amanda decides to invest in two different no-load mutual funds: the G Fund or the L Mutual Fund. At the end of each year, she liquidates her holdings, takes her profits, and then reinvests. The yearly profits of the mutual funds depend on where the market stood at the end of the preceding year. Recently the market has been oscillating around level 2 from one year end to the next, according to the probabilities given in the following transition matrix : L1 L2 L3 L1 0.2 0.4 0.4 L2 0.1 0.4 0.5 L3 0.3 0.3 0.4 Each year that the market moves up (down) 1 level, the G Fund has profits (losses) of $20k, while the L Fund has profits (losses) of $10k. If the market moves up (down) 2 level in a year, the G Fund has profits (losses) of $50k, while the L Fund has profits (losses) of only $20k.
