In Multi-Agent Reinforcement Learning (MARL), what is the primary challenge that distinguishes it from single-agent RL?

  1. The need for centralized decision-making.

  2. The presence of multiple agents with potentially conflicting goals.

  3. The requirement for perfect information about the environment.

  4. The lack of a well-defined reward function.


Correct Option: B
Explanation:

In MARL, the presence of multiple agents with potentially conflicting goals introduces the challenge of coordinating their actions and learning strategies to achieve optimal outcomes.

Which of the following is a common approach for solving MARL problems?

  1. Centralized training and decentralized execution.

  2. Decentralized training and centralized execution.

  3. Fully centralized training and execution.

  4. Fully decentralized training and execution.


Correct Option: A
Explanation:

Centralized training and decentralized execution is a widely used approach in MARL, where agents are trained jointly in a centralized manner but execute their actions independently based on local observations.

In MARL, what is the term used to describe the situation where agents' actions affect each other's rewards?

  1. Positive externalities.

  2. Negative externalities.

  3. Interdependence.

  4. Coordination.


Correct Option: C
Explanation:

Interdependence in MARL refers to the situation where the actions of one agent directly or indirectly influence the rewards of other agents.

Which of the following is a common type of MARL algorithm that assumes agents have access to global information?

  1. Independent Learners.

  2. Team Learners.

  3. Centralized Learners.

  4. Decentralized Learners.


Correct Option: C
Explanation:

Centralized Learners assume that agents have access to global information and make decisions based on this shared knowledge.

In MARL, what is the term used to describe the situation where agents have limited or no information about the actions of other agents?

  1. Full observability.

  2. Partial observability.

  3. Perfect information.

  4. Imperfect information.


Correct Option: B
Explanation:

Partial observability in MARL refers to the situation where agents have limited or incomplete information about the actions and states of other agents.

Which of the following is a common type of MARL algorithm that assumes agents have limited or no information about the actions of other agents?

  1. Independent Learners.

  2. Team Learners.

  3. Centralized Learners.

  4. Decentralized Learners.


Correct Option: D
Explanation:

Decentralized Learners assume that agents have limited or no information about the actions of other agents and make decisions based on local observations.

In MARL, what is the term used to describe the situation where agents have conflicting goals?

  1. Cooperative learning.

  2. Adversarial learning.

  3. Competitive learning.

  4. Collaborative learning.


Correct Option: B
Explanation:

Adversarial learning in MARL refers to the situation where agents have conflicting goals and compete against each other to achieve their own objectives.

Which of the following is a common type of MARL algorithm that is designed for adversarial settings?

  1. Independent Learners.

  2. Team Learners.

  3. Centralized Learners.

  4. Game Theoretic Learners.


Correct Option: D
Explanation:

Game Theoretic Learners employ game theory concepts to find optimal strategies for agents in adversarial settings.

In MARL, what is the term used to describe the situation where agents have aligned goals and work together to achieve a common objective?

  1. Cooperative learning.

  2. Adversarial learning.

  3. Competitive learning.

  4. Collaborative learning.


Correct Option: A
Explanation:

Cooperative learning in MARL refers to the situation where agents have aligned goals and collaborate to achieve a common objective.

Which of the following is a common type of MARL algorithm that is designed for cooperative settings?

  1. Independent Learners.

  2. Team Learners.

  3. Centralized Learners.

  4. Game Theoretic Learners.


Correct Option: B
Explanation:

Team Learners are designed for cooperative settings and aim to find joint strategies that maximize the collective reward of all agents.

In MARL, what is the term used to describe the situation where agents learn from each other's experiences?

  1. Imitation learning.

  2. Social learning.

  3. Transfer learning.

  4. Reinforcement learning.


Correct Option: B
Explanation:

Social learning in MARL refers to the situation where agents learn from each other's experiences and adapt their strategies accordingly.

Which of the following is a common type of MARL algorithm that utilizes social learning?

  1. Independent Learners.

  2. Team Learners.

  3. Centralized Learners.

  4. Multi-Agent Deep Reinforcement Learning (MADRL).


Correct Option: D
Explanation:

MADRL algorithms incorporate social learning mechanisms, allowing agents to learn from each other's experiences and improve their joint performance.

In MARL, what is the term used to describe the situation where agents communicate with each other to coordinate their actions?

  1. Centralized communication.

  2. Decentralized communication.

  3. Full communication.

  4. Limited communication.


Correct Option: B
Explanation:

Decentralized communication in MARL refers to the situation where agents can communicate with each other, but the communication is limited or restricted.

Which of the following is a common type of MARL algorithm that utilizes decentralized communication?

  1. Independent Learners.

  2. Team Learners.

  3. Centralized Learners.

  4. Multi-Agent Communication Networks (MACNs).


Correct Option: D
Explanation:

MACNs are designed for decentralized communication settings and allow agents to exchange information and coordinate their actions effectively.

In MARL, what is the term used to describe the situation where agents learn to adapt their strategies based on the actions and observations of other agents?

  1. Adaptive learning.

  2. Reinforcement learning.

  3. Imitation learning.

  4. Social learning.


Correct Option: A
Explanation:

Adaptive learning in MARL refers to the situation where agents learn to adapt their strategies based on the actions and observations of other agents.

Which of the following is a common type of MARL algorithm that utilizes adaptive learning?

  2. Team Learners.

  3. Centralized Learners.

  4. Multi-Agent Adaptive Learning (MAAL).


Correct Option: D
Explanation:

MAAL algorithms incorporate adaptive learning mechanisms, allowing agents to adjust their strategies in response to changes in the environment and the actions of other agents.
