LILBANK is a bank with four rooms, every adjacent room is connected with the door. All rooms also have an external door. There is a security agent (Guard G) in the bottom leftmost corner. There is a thief T somewhere in the bank. Guard’s job is to move from one room to the next, check if the external door is locked are not, and relay a message for the police as follows: (OK if the door is locked and there is no thief; NAK if it orders phone unlocked and HELP if there is a thief found in the same room as the agent).

a) Draw a diagram to fully represent the above as an agent-based AI world problem.

b) Provide an agent program (pseudocode) for a simple reflex agent first. Then modify this program to represent a model-based agent.
