Describe the four types of agents with a neat diagram. 1)simple reflex agent, 2)Model-based agent, 3)Utility-based agent, 4)Goal-based agent
Sure! Here's a description of the four types of agents along with a neat diagram:
Simple Reflex Agent: A simple reflex agent selects actions based only on the current percept or input without considering the history or future consequences. It follows condition-action rules to map percept sequences directly to actions. The agent uses a set of predefined rules to determine the best action to take based on the current state. It does not consider the current state's implications for future states.

Model-Based Agent: A model-based agent maintains an internal model of the environment and uses it to keep track of the current state. It updates the model based on perceptual input and uses the model to plan future actions. By maintaining an internal representation of the environment, the agent can make more informed decisions by considering the effects of its actions on the future state.

Utility-Based Agent: A utility-based agent selects actions by evaluating the expected utility or value of the different outcomes. It considers not only the current state and the available actions but also the potential consequences of each action. The agent assigns utility values to different states or outcomes and selects the action that maximizes the expected utility.

Goal-Based Agent: A goal-based agent selects actions based on its goal or objective. It maintains a set of goals and selects the actions that will bring it closer to achieving those goals. The agent uses a combination of information from the current state and its internal knowledge about environment to determine the best actions to take.
