Question

Consider a grid with ‘n’ rows and ‘m’ columns. The agent will start at a particular cell and its job will be to move to a goal cell. The agent will have the following actions available to it: 1. Move up, the cost of this actions is +2 2. Move down, the cost of this action is -1 3. Move Right, the cost of this action is +1.5 4. Move Left, the cost of this action is -0.5 The agent wants to find a path between the starting cell and the goal cell in as low of a cost as possible. However, the grid has special cells marked as ‘W’ and ‘X’, if your agent moves to the ‘W’ cell, then the agent will be teleported a cell (randomly selected) next to the goal state, but the cost will be ‘+7’. If your agent moves to the ‘X’ cell then your agent will be teleported to the starting however, the cost will be ‘-7’. For example, take a look at a 7 x 8 grid below: L W L G W A Here the agent is at the position (0,0), and the goal is at the position (3,7). If the agent moves to the ‘W’ cell at (4,2), then the agent will be transported to either (3,6) or (2,7) or (4,7). Given the scenario above, answer the following questions: 1. What is the PEAS description of the agent? 2. Describe its task environment. 3. Model this problem as a search problem 4. What is the branching factor of this problem?
