Develop a simulation that shows the actions you can run an intelligent agent on a System based on the learned knowledge. For this model you must use a language high-level programming.
The essence of model-free learning is the policy iteration. Please match the phase and the descriptions/exmples.
a. Policy Evaluation
b. Policy Improvement
Greedily select an action from the Q-Value table
Update Q-Value table
Know how to "good" a policy is.
Make adjustments toward the "good" decision

- Write a Java program to simulate the behavior of a model-based agent for a vacuum cleaner environment based on the following conditions: The vacuum cleaner can move to one of 4 squares: A, B, C, or D as shown in Table 1. Table 1: vacuum cleaner environment A B C D The vacuum cleaner checks the status of all squares and takes action based on the following order: If all squares are clean, the vacuum cleaner stays in its current location. If the current location is not clean, the vacuum cleaner stays in its current location to clean it up. The vacuum cleaner can only move horizontally or vertically (cannot move diagonally). The vacuum cleaner moves only one square at a time. Horizontal moves have the highest priority over vertical moves. The vacuum cleaner moves to another square only when it needs to be cleaned up.

When more than one of the variables is unknown, the outcome is difficult to visualize. A common way to overcome this difficulty is to simulate the scenario many times and count the number of times different ranges of outcomes occur. One such popular simulation is called a Monte Carlo Simulation. In this problem-solving exercise you will develop a program that will perform a Monte Carlo simulation on a simple profit function. Consider the following total profit function: PT=nPv Where Pr is the total profit, n is the number of vehicles sold and P, is the profit per vehicle. PART A Compute 5 iterations of a Monte Carlo simulation given the following information: n follows a uniform distribution with minimum of 1 and maximum 10 P, follows a normal distribution with a mean…arrow_forward

The following are the action schema:1. goto(r, x1, x2) : robot r go to x2 from x12. switchON(s): switchON the bulb s3. switchOFF(s): switchOFF the bulb s 1. Write down preconditions and effects of the above actions. 2. Consider the following: (i) Initial state: < R1;R2;B1;B2 >: Robot is at Room R1 not in Room R2 and both bulbs are off.(ii) Goal state: < R2;B1;B2 >: Robot is at Room R2 and both bulbs are ON.Draw state space diagram for the above by drawing to all possible states.arrow_forward2. Suppose that an agent is in a 3×3 maze environment like the one shown in Figure 4.19. The agent knows that its initial location is (1,1), that the goal is at (3,3), and that the four actions *Up*, *Down*, *Left*, *Right* have their usual effects unless blocked by a wall. The agent does *not* know where the internal walls are. In any given state, the agent perceives the set of legal actions; it can also tell whether the state is one it has visited before or is a new state. a. Explain how this online search problem can be viewed as an offline search in belief‐state space, where the initial belief state includes all possible environment configurations. How large is the initial belief state? How large is the space of belief states? b. How many distinct percepts are possible in the initial state? c.
