Artificial Intelligence Principles and Logic Systems
Search and Problem Solving in AI
1. Define AI
Artificial Intelligence (AI) is the branch of computer science that develops machines capable of performing tasks that normally require human intelligence.
2. What is an Intelligent Agent?
An Intelligent Agent is an entity that perceives its environment through sensors and acts upon it using actuators to achieve goals.
3. Define a Problem-Solving Agent.
A Problem-Solving Agent is an intelligent agent that finds a sequence of actions to reach a goal from an

N-Gram Models: Unigram, Bigram, and Trigram
An N-Gram Model is a statistical language model that predicts the next word based on the previous 
words.
Types of N-Grams
Unigram (N=1)
Considers each word independently.
Example sentence: I love NLP
Unigrams:
- I
- love
- NLP
Probability: 
Bigram (N=2)
Considers one previous word.
Bigrams:
- I love
- love NLP
Probability: 
Trigram (N=3)
Considers two previous words.
Trigrams:
- I love NLP
Probability: 
Applications of N-Grams
- Text prediction
- Spell checking
- Speech recognition
- Machine translation
- Chatbots

Generative Language Models
Definition: A Generative Language Model learns the probability distribution of words in a language and generates new text by predicting the next word or sequence of words based on context.
Example: For the input “The sun rises in the,” the model may predict “east,” resulting in “The sun rises in the east.”
Advantages
- Produces coherent text
- Useful for content generation
- Learns from large text corpora
- Supports various NLP applications

1. Disk Scheduling Algorithms
In traditional Hard Disk Drives (HDDs), data is read and written by a mechanical disk head moving across spinning platters. Because mechanical movement is slow, the operating system uses Disk Scheduling Algorithms to order incoming I/O requests. The main goal is to minimize Seek Time (the time it takes for the disk head to move to the required cylinder).
To compare these algorithms, let’s use a standard example:
- Total Cylinders: 0 to 199 (200 total tracks)
- Current Head

Numbers and Math
- Arithmetic:
+,-,/,//(floor),%(remainder),**(exponent). - Shorthand:
a += 2(also-=,*=,//=). - Functions:
abs(-3.5),round(3.56, 1),max(3.56, 4.57).
Strings and Formatting
- Quotes:
'spam eggs',"doesn't". - Newline:
print('\n'). - F-Strings:
f'Price {cost:.2f}',f'{ratio:.2%}'.
Data Types
int(whole),float(decimal),str(text),bool(True/False).- Input:
input()(returns string),int(input())(converts to integer).

age = int(input('Enter your age: ')) if age >= 18: print(
