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 it goains are, in order to fix its behavior. Give an Example:
Give the initial state, goal test, actions/operators, and path cost for the following description. There are several possible formulations for the problem, with varying levels of detail. Pay special attention to different path costs for various actions, and conditions for when those actions are valid. The main thing is that your formulation should be precise and “hang together” so that it could actually be implemented.
A monkey is in a room with a crate, with bananas suspended just out of reach on the ceiling. He would like to get the bananas
Consider an agent for a vacuum cleaner environment in which the geography of the environment (extent, boundaries, and obstacles) is unknown as is the initial dirt configuration. The agent can go up and down as well as left and right. Can a simple reflex agent be perfectly rational for this environment? Explain in a few sentences using an example scenario

- Consider a robot that is capable of picking objects from a shelf and placing them on the table. Suppose that the robot’s arm works perfectly, and the environment is fully-observable. (i) Define a STRIPS operator that could be used for planning the actions of this robot. (ii) Give an example of a state S of the world at which this STRIPS operator is applicable. (iii) Describe the operation of this STRIPS operator at this state S, to show the next state S0 of the world.arrow_forwardIn reinforcement learning, we have to predict an action or value of a state/action, this is like a supervised learning task. What makes reinforcement learning more difficult than classification? Select one: a. It is hard to get samples. b. The supervision is delayed c. There is no supervision in any form. d. It is hard to make a state.arrow_forwardFor the goal-based agent architecture given in the picture, write the pseudocode for the agent, given the following: function GOAL-BASED-AGENT (percept) returns an action persistent: state, the agent’s current conception of the world state model, a description of how the next state depends on the current state and action goal, a description of the desired goal state plan, a sequence of actions to take, initially empty action, the most recent action, initially nonearrow_forward

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 neighbor vertical square first. The vacuum cleaner action is…arrow_forwardFormulate your own argument (make it creative!) and draw a suitable Euler diagram for it. Justify as well whether it is valid or not. You may emulate the four given arguments below. Example: All Filipinos enjoy singing. Juan is a Filipino. Therefore, Juan enjoys singing. Some physicists are poets. Einstein is a physicist. Therefore, Einstein is a poet. All lions are animals. Some lions have manes.Therefore, some animals have manes. All booms (B) are zooms (Z). All feeps (F) are meeps (M). No boom is a feep.

- The PDDL is put to use in order to provide a description of a made-up setting known as the JUNGLE. This universe has a total of five constants and three predicates, each of which may take a maximum of four arguments. There should be a limit placed on the total number of states on this JUNGLE planet.
