Create a function mean comp that compares the mean value of the odd numbered elements with
the mean value of the even numbered elements and returns: if they are equal, if the mean of the
odd numbered elements is greater, if the mean of the even numbered elements is greater.
Solution
A sample Java Program methods
public static void main(String []args){
float[] list = {1.0f, 7.0f, 8.0f, 1.0f};
System.out.println(meancomp(list));
}
static int meancomp(float[] list) {
float evenSum = 0.0f;
float oddSum = 0.0f;
for (int i = 0; i < list.length; i++) {
if (i % 2 == 1)
evenSum = evenSum + list[i];
else
oddSum = oddSum + list[i];
}
int noOfEvenElements = list.length / 2;
int noOfOddElements = list.length / 2 + list.length % 2;
float evenMean = evenSum / (float) noOfEvenElements;
float oddMean = oddSum / (float) noOfOddElements;
int result = Float.compare(evenMean, oddMean);
if (result == 0)
return 0;
else if (result < 0)
return 1;
else
return 2;

Define a knowledge-based agent, and describe its major components. W.pdf
1. Define a knowledge-based agent, and describe its major components. What is knowledge
representation? What KR formalisms do you know-- explain and compare them (be sure to
include PL, FOL, semantic nets and frames)
Solution
A knowledge-based agent includes a knowledge base and an inference system. A knowledge
base is a set of representations of facts of the world.Each individual representation is called a
sentence.The sentences are expressed in a knowledge representation language.
The agent operates as follows:
1. It TELLs the knowledge base what it perceives.
2. It ASKs the knowledge base what action it should perform.
3. It performs the chosen action.
Major Components are as follows:
•Knowledge Level.
The most abstract level: describe agent by saying what it knows.
•Logical Level.
The level at which the knowledge is encoded into sentences.
•Implementation Level.
The physical representation of the sentences in the logical level.
