the knowledge-based agent is not an arbitrary program for calculating actions. It is amenable to a description at the knowledge level, where we need specify only what the agent knows and what its goals are, in order to fix its behavior. Give an Example ?
2. 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. Describe the first few branches of a contingency plan for this problem. How large
(roughly) is the complete plan?
Notice that this contingency plan is a solution for *every possible…
Write a Java program to simulate the behaviour 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. If a diagonal square needs to be cleaned up, the vacuum cleaner moves to its neighbour vertical square first.
The vacuum cleaner action is…

- . The vacuum cleaner problem is a well-known search problem for a vacuum cleaner robot that works on Artificial Intelligence. In this problem to clean up the whole area. In the superficial world, the vacuum cleaner agent has a location sensor and a dirt sensor to know where it is (room A, room B, or any n room) and whether the room is dirty. Also, the robot needs to avoid the obstacle (stool) and find a new path. A possible performance measure is to maximize the number of clean rooms over a certain period. For this problem, four main conditions should be considered: in(x,y) means a robot at (x,y) dirt(x,y) means there is a dirt at(x,y) facing(d) means the robot is facing direction d, where d ={north, east, south, west} • hit(s) means the robot hits the obstacle s possible actions the robot can do - turn, forward, suck-dirt, avoid a) Write possible rules that can be used to perform the room cleaning plan b) Execute this plan…arrow_forwardAn agent can learn to play chess by supervised learning-by being given examples of game situations along with the best moves for those situations.
