ABCᎠFdEFigure 1: The Blocks WorldAnswer the following questions:• Write the precondition axioms for the actions..Write the effect axioms for the actions.Similarly, we have only two fluents:On(x, y, s) which holds when block x is on block y, andOn Table(x, s) which holds when block x is on the table.• Show how successor state axioms for the fluents would be derived from these effect axioms.Argue that the successor state axioms are not logically entailed by the effect axioms bybriefly describing an interpretation where the effect axioms are satisfied but the successorstate ones are not.• Show how frame axioms are logically entailed by the successor state axioms. (Ex. 1 in Ch14 of the book KRR) Blocks World Imagine that we have a collectionof blocks on a table and a robot arm that is capable of picking up blocks and putting themelsewhere, as shown in Figure 1.We assume that the robot arm can hold at most one block at a time. We also assume thatthe robot can only pick up a block if there is no other block on top of it. Finally, we assumethat a block can only support or be supported by at most one other block, but that the tablesurface is large enough that all blocks can be directly on the table. There are only two actionsavailable:puton(x, y) which picks up block x and moves it onto block y, andputonTable(x) which moves block x onto the table.

Dear Student, The fluents available are On(x,y,s) which holds when block x is on block y, and…

Answer the following questions: • Write the precondition axioms for the actions. • Write the effect axioms for the actions. • Show how successor state axioms for the fluents would be derived from these effect axioms. Argue that the successor state axioms are not logically entailed by the effect axioms by briefly describing an interpretation where the effect axioms are satisfied but the successor state ones are not. • Show how frame axioms are logically entailed by the successor state axioms.

Propose a UML class diagram for this repair management system. A company want to manage repair requests of its employees. Each employeebelongs to a department. The system will allow the employee of each departmentto create a ticket which include the details of the repair request. The ticket will bemanaged by a different employee. Of each ticket an appointment must bescheduled base on the availability of the ticket initiator and the repair employee.To do the required repair this employee may use some resources. A list of resourcewill be assigned to each ticket. This list include resource that could be infrastructureresource or technology resources. Once the repair is done, the status of the repairmust be tagged as completed

A robot moves into rooms R1 and R2 and switch the bulbs B1 and B2 on/off. 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.
