What is the difference between agent function and agent program?

What is the difference between agent function and agent program?

An agent function is an abstract mathematical mapping from percept sequences to actions; an agent program is a specific implementation in a system. An agent function processes information from the agent’s sensors; an agent program controls the agent’s actuators.

What is an agent agent function and agent program?

Agent function: This is a function in which actions are mapped from a certain percept sequence. Percept sequence refers to a history of what the intelligent agent has perceived. Agent program: This is an implementation or execution of the agent function.

What is agent function?

An agent is authorized to act on behalf of another person. People hire agents to perform tasks that they lack the time or expertise to do for themselves. A universal agent has wide authority to act on another’s behalf, but a general agent or special agent has more limited and specific powers.

What is an agent program in artificial intelligence?

An intelligent agent is a program that can make decisions or perform a service based on its environment, user input and experiences. These programs can be used to autonomously gather information on a regular, programmed schedule or when prompted by the user in real time.

What are the four basic types of agent program in any intelligent system?

Agents can be grouped into four classes based on their degree of perceived intelligence and capability :

• Simple Reflex Agents.
• Model-Based Reflex Agents.
• Goal-Based Agents.
• Utility-Based Agents.
• Learning Agent.

Can there be more than one agent program that implements a given agent function?

Yes there may be more than one agent program that implements an agent function. Yes there are agent functions that cannot be implemented by any agent program. One example function would be the halting problem.

What does an intelligent agent map to actions?

The program agent, instead, maps every possible percept to an action. In the following figures, an agent is anything that can be viewed as perceiving its environment through sensors and acting upon that environment through actuators.

What’s the difference between an agent and a function?

The job of AI is to design an agent program that implements the agent function — the mapping from percepts to actions. Notice the difference between the agent program, which takes the current percept as input, and the agent function, which takes the entire percept history. Why does the agent program only take current percept?

Can a function be implemented by an agent program?

If the agent itself does not have the capacity to perform the function, then it cannot possibly be implemented by the agent program. Moreover, agent functions that are nonsensical or do not have logical bases to them would be difficult to implement. c) Given a fixed machine architecture, does each agent program implement exactly one agent function?

Is it possible to have more than one agent program?

Yes, it is possible to have more than one agent program that implements a given agent function. For example, consider an agent that sums up a list of numbers. One agent program could implement this function by going straight down the list of numbers to find their sum.

Can a machine have 2 ^ n different agent programs?

If the architecture has n bits of storage, it allows for 2^n different agent programs. e) Suppose we keep the agent program fixed but speed up the machine by a factor of two. Does that change the agent function? No, the agent function does not change if the machine is sped up.
