10. Lecture Notes on AI & NN Chapter 4 Information Representation A General Introduction

11. Objectives: 1. Make the information convenient to use 2. Make it recognizable to machines Requirements: 1. Powerful in expression 2. Easy to be understood by machine 3. Convenient to be manipulated The Key Points of Representation: The states and the way of states varying should be suitably represented.

12. Section 1 Logic Approach Both propositional and predicate logic can be used. The latter is however more powerful than the former. Examples: Robot Table A Table B The Alcove Box

13. Situation Representation 1) AT (ROBOT, ALCOVE) EMPTYHANDED (ROBOT) ON (BOX, A) TABLE (A) TABLE (B) 2) AT (ROBOT, A) HOLDS (ROBOT, BOX) TABLE (A) TABLE (B)

14. Operation Representation Pick up Box from A Condition: ON (BOX, A) AT (ROBOT, A) EMPTYHANDED (ROBOT) Delete: EMPTYHANDED (ROBOT) ON (BOX, A) Add: HOLDS (BOX) Action Series (Plan) Representation Asking robot at alcove to move box from A

15. Homework Represent & solve the given problem by logic approach The Monkey & Bananas Problem A hungry monkey finds himself in a room in which a bunch of bananas is hanging from the ceiling. The monkey, unfortunately, cannot reach the bananas. However, in the room there is also a desk. The ceiling is just the right height so that a monkey standing on a desk could knock the bananas down. What is the best sequence of actions for the monkey to take the bananas ?

16. Section 2 State Space, Graph, & Semantic Net 2-1 State Space Examples The health information can be represented by body temperature, blood pressure, complexion, number of white-blood-cell, … The nation development can be represented by output of industry, output of agriculture, education index, expenses index, …

17. A General form of state-space-mapping Example: The game of coins turning-over Suppose that one has 3 coins with S and G given. It is allowed to turn 1 piece of the coins over at a time. Is it possible to transform the coins from S to G in 3 turnings ? +-- +++ -- - Start State S Goal States G

19. Homeworks: The Missionaries & Cannibals Problems Three missionaries (Ms) and three cannibals (Cs) happen to meet on one side of a river. They all want to get to the other side. Unfortunately, there is only one boat available which can carries two people at a time. It is a well-known rule that whenever the number of Ms is less than that of Cs, the Ms will be eaten by Cs. The problem is now that how everyone can get across the river without Ms being eaten.
