10 Questions
What is the term used for an environment with more than one agent, where each agent is an opponent of the other?
Adversarial environment
Why is game playing considered an attractive area for AI research?
Because it offers a pure abstraction of competition between two armies
What did Claude Shannon and Alan Turing do in 1950 related to game programs?
They developed the first game program for chess
Why are adversarial searches often known as games?
Because they involve two or more players with conflicting goals exploring the same search space
What is the key to success in adversarial situations?
Being able to think several moves ahead
What type of game involves complete information about the game and allows agents to see each other's moves?
Perfect information game
Which game type is characterized by having various unpredictable events and introduces factors of chance or luck?
Non-deterministic game
In which type of games is each agent's gain or loss of utility exactly balanced by the gains or losses of utility of another agent?

The legal moves a player can make
Study Notes
Multi-Agent Environments
- An environment with more than one agent, where each agent is an opponent of the other, is referred to as a multi-agent environment.
Attractive Area for AI Research
- Game playing is considered an attractive area for AI research because it provides a competitive environment for testing and improving AI systems.
Claude Shannon and Alan Turing
- In 1950, Claude Shannon and Alan Turing worked on developing game programs, laying the foundation for AI research in game playing.
Adversarial Searches
- Adversarial searches are often referred to as games because they involve opposing agents making strategic decisions to outmaneuver each other.
Key to Success in Adversarial Situations
- The key to success in adversarial situations is to make optimal decisions based on the opponent's possible moves and strategies.
Types of Games
- Perfect information games involve complete information about the game and allow agents to see each other's moves.
- Imperfect information games are characterized by having various unpredictable events and introduce factors of chance or luck.
- Zero-sum games are those in which each agent's gain or loss of utility is exactly balanced by the gains or losses of utility of another agent.
Optimal Move Algorithm
- The Minimax algorithm is used to choose an optimal move for a player, assuming that the other player is also playing optimally.
Successor Function in Game Trees
- The successor function defines the possible next states or moves in a game tree, representing the outcome of a particular action or decision.
Explore the concept of adversarial search in multi-agent environments where each agent is an opponent of another, and they play against each other. Understand how agents need to consider the actions of their opponents and the effects of those actions.
