Artificial Intelligence Tutorial | AI Tutorial
Artificial Intelligence (AI) refers to the simulation of human intelligence in machines which helps in allowing them to think and act like humans. It involves creating algorithms and systems that can perform tasks which requiring human abilities such as visual perception, speech recognition, decision-making and language translation.
Types of Artificial Intelligence
Artificial Intelligence (AI) is classified into:
What is an AI Agent?
An AI agent is a software or hardware entity that performs actions autonomously with the goal of achieving specific objectives.
Problem Solving in AI
Problem-solving is a fundamental aspect of AI which involves the design and application of algorithms to solve complex problems systematically.
1. Search Algorithms in AI
Search algorithms navigate through problem spaces to find solutions.

2. Local Search Algorithms
Local search algorithms operates on a single current state (or a small set of states) and attempt to improve it incrementally by exploring neighboring states.
3. Adversarial Search in AI
Adversarial search deal with competitive environments where multiple agents (often two) are in direct competition with one another such as in games like chess, tic-tac-toe or Go.
4. Constraint Satisfaction Problems
Constraint Satisfaction Problem (CSP) is a problem-solving framework that involves variables each with a domain of possible values and constraints limiting the combinations of variable values.
