What is the generic structure of Multi Agent System (MAS) ?
Multiagents with diverse objectives and communication abilities
Understanding Multi Agent System (MAS) Structure
A Multi-Agent System (MAS) is a distributed system composed of multiple interacting intelligent agents. These systems are designed to solve complex problems that might be difficult or impossible for a single agent or a monolithic system to solve.
The generic structure of a Multi Agent System involves several key characteristics:
- Multiple Agents: A MAS inherently consists of more than one agent. Each agent is an autonomous entity capable of perceiving its environment and acting upon it.
- Diverse Objectives: While agents in a MAS might cooperate towards a common goal, individual agents often have their own, potentially diverse or even conflicting, objectives. This diversity is a crucial aspect that distinguishes MAS from simpler distributed systems.
- Communication Abilities: Agents in a MAS need to interact and communicate with each other to coordinate actions, share information, negotiate, or compete. Communication is essential for achieving system-level goals and managing individual agent behaviors.
Analyzing the Options for MAS Structure
Let's evaluate the given options based on the fundamental characteristics of a Multi Agent System:
| Option | Analysis | Conclusion |
|---|---|---|
| Single agent with multiple objectives | This describes a single entity, not a "Multi" Agent System, which requires multiple agents. | Incorrect |
| Multiagents with a single objectives | This option includes "Multiagents" but limits them to a "single" objective. While agents might work towards a common goal, the generic structure often involves agents with individual, potentially diverse objectives that they balance with cooperation. | Less accurate as a generic structure description |
| Multiagents with diverse objectives and communication abilities | This option correctly identifies the presence of multiple agents ("Multiagents"), acknowledges that these agents can have varied objectives ("diverse objectives"), and highlights the necessity for interaction ("communication abilities"). These are core components of a generic MAS structure. | Correct |
| Multiagent with two objectives | This option uses "Multiagent" (should be Multiagents) and specifically limits the number of objectives to "two", which is overly specific and not representative of the generic "diverse objectives" found in many MAS. | Incorrect and overly specific |
Based on the analysis, the option that best describes the generic structure of a Multi Agent System (MAS) is one where there are multiple agents, they possess diverse objectives, and they have the ability to communicate with each other.

| Agents | Autonomous entities capable of perception, decision-making, and action. |
| Multiple Agents | Requirement for more than one agent to form a MAS. |
| Diverse Objectives | Agents may have individual goals, which could be complementary, competitive, or conflicting, alongside potentially shared goals. |
| Communication | Ability of agents to exchange information, coordinate, and interact using specific protocols. |
| Environment | The context in which agents operate and interact. |
Additional Information on Multi Agent System Design
Designing Multi Agent Systems involves considering various aspects beyond just their basic structure. Some important related concepts include:
- Agent Architectures: How individual agents are built (e.g., reactive, deliberative, hybrid).
- Interaction Protocols: The rules governing how agents communicate and interact (e.g., negotiation, auction, voting).
- Coordination Mechanisms: Methods used to manage agent interactions to achieve desired system outcomes (e.g., coalition formation, task allocation).
- System Evaluation: Assessing the performance of the MAS based on criteria like efficiency, robustness, and adaptability.
- Application Domains: MAS are applied in various fields such as robotics, logistics, simulations, gaming, and smart grids.

A stone is thrown horizontally from the top of a 20 m high building with a speed of 12 m/s. It hits the ground at a distance R from the building. Taking g = 10 m/s2 and neglecting air resistance will give :
A sphere of volume V is made of a material with lower density than water. While on Earth, it floats on water with its volume f1V (f1 < 1) submerged. On the other hand, on a spaceship accelerating with acceleration a < g (g is the acceleration due to gravity on Earth) in outer space, its submerged volume in water is f2V. Then:
A railway wagon (open at the top) of mass M1 is moving with speed v1 along a straight track. As a result of rain, after some time it gets partially filled with water so that the mass of the wagon becomes M2 and speed becomes v2. Taking the rain to be falling vertically and the water stationery inside the wagon, the relation between the two speeds v1 and v2 is :
Consider the following statements:
1. Distance between the longitudes becomes zero on North Pole and South Pole.
2. Distance between the longitudes is maximum on the Equator.
3. Number of longitudes is more than number of latitudes.
Which of the statements given above is/are correct?
One block of 2⋅0 kg mass is placed on top of another block of 3⋅0 kg mass. The coefficient of static friction between the two blocks is 0⋅2. The bottom block is pulled with a horizontal force F such that both the blocks move together without slipping. Taking acceleration due to gravity as 10 m/s2, the maximum value of the frictional force is :
