AI Concepts Quiz

What does an AI agent perceive to make decisions?

• Actions

• Environment

• Sensors

• Goals

A fully observable environment means the agent:

• Has limited information

• Can perceive the entire state of the environment at all times

• Acts randomly

• Has no knowledge of the environment

Which of the following agents maintains an internal state to handle partially observable environments?

• Simple reflex agent

• Model-based reflex agent

• Goal-based agent

• Utility-based agent

The concept of rationality in AI means the agent:

• Chooses actions randomly

• Chooses actions that maximize expected performance

• Always acts optimally regardless of environment

• Does not learn from experience

Which of the following is NOT an uninformed search algorithm?

• Breadth-First Search

• Depth-First Search

• A* Search

• Uniform Cost Search

In informed search strategies, the function used to estimate the cost from the current state to the goal is called:

• Path cost

• Heuristic function

• Utility function

• Performance measure

Which search algorithm expands the shallowest unexpanded node first?

• Depth-First Search

• Breadth-First Search

• Uniform Cost Search

• Greedy Best-First Search

What is the primary disadvantage of Depth-First Search (DFS)?

• Requires a lot of memory

• Can get stuck in infinite loops

• Always finds the shortest path

• Uses heuristics inefficiently

The goal of a problem-solving agent is to:

• Explore the environment randomly

• Find a sequence of actions leading to the goal state

• Execute predefined actions without searching

• Learn new goals automatically

Which of the following best describes a static environment?

• Environment changes over time

• Environment remains unchanged while agent is deciding

• Environment is unpredictable

• Agent cannot perceive environment
