In a coin game, you repeatedly toss a biased coin (0.4 for head, 0.6 for tail). Each head represents 3 points and tail represents 1 point. You can either Toss or Stop if the total number of points you have tossed is no more than 7. Otherwise, you must Stop. When you Stop, your utility is equal to your total points (up to 7), or 0 if you get a total of 8 points or higher. When you Toss, you receive no utility. There is no discounting (= 1).

(a) What are the states and the actions for this MDP? Which states are terminal?
(b) What is the transition function and the reward function for this MDP? Hint: The problem may be simpler to formulate using the general version of rewards: R(s, a, s')
(c) Run value iteration to find the optimal value function V* for the MDP. Show each Vk step (starting from Vo(s) = 0 for all states s). For a reasonable MDP formulation, this should converge in fewer than 10 steps. If you find it too tedious to do by hand, you may write a program to do this for you; however, there may be some benefit in seeing the calculation unfolding in front of you.
(d) Using the V* you found, determine the optimal policy for this MDP.

See answer in explanation

Step-by-step explanation:

State: current points if stop plus a terminal state, that is, 0,1,2,3,4,5,6,7,DONE

Action: Toss, Stop

2. What is the transition function and the reward function for this MDP?

Transition function:

T(Si , TOSS, Si+3) = 0.4 if i < 3

T(Si , TOSS, DONE) = 0.4 if i ≥ 3

T(Si , TOSS, Si+1) = 0.6 if i < 7

T(Si , TOSS, DONE) = 0.4 if i = 7

T(Si , STOP, DONE) = 1

Reward function:

R(Si , TOSS, ANY ) = 0

R(Si , STOP, DONE) = i

R(DONE, STOP, DONE) = 0

3. What is the optimal policy for this MDP? Please write down the steps to show how

you get the optimal policy.

Optimal policy: Toss for 0,1,2 ; STOP for others.

You should include the steps of value iteration. The value iteration will converge at

iteration 3. Result of iteration 3 is as follow,

V3: 0: 4.5 from Toss; 1: 5.4 from Toss; 2: 5.9 from Toss; 3: 3 from

Stop; 4: 4 from Stop; 5: 5 from Stop; 6: 6

q: 92 degrees

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )
