Types of AI Agents
Types of AI agents that can be categorized based on their functionality, complexity, and the tasks they are designed to perform. Here are some common types of AI agents and their use cases:
1. Simple Reflex Agents

Route-planning apps like Google Maps.
Game-playing AI (e.g., chess or Go).
4. Utility-Based Agents
Description: These agents aim to maximize a utility function, which represents the agent's performance measure. They evaluate actions based on how well they achieve desired outcomes.
Use Cases:
Recommendation systems (e.g., Netflix, Amazon).

6. Multi-Agent Systems
Description: These systems involve multiple AI agents that interact, collaborate, or compete with each other to achieve individual or shared goals.
Use Cases:
Autonomous drone swarms for search and rescue.
Collaborative robots (cobots) in manufacturing.

Team-based gaming AI.
14. Adversarial Agents
Description: These agents operate in competitive environments, often trying to outperform opponents.
Use Cases:
Game-playing AI (e.g., AlphaGo, poker bots).
Cybersecurity systems that detect and counter threats.
Fraud detection in financial systems.
15. Swarm Agents
Description: These agents are part of a decentralized system where individual agents follow simple rules, leading to emergent collective behavior.
Use Cases:
Swarm robotics for agriculture or disaster response.
Traffic management systems.
Distributed computing systems.
16. Cognitive Agents
Description: These agents mimic human cognitive processes, such as reasoning, learning, and problem-solving.
Use Cases:
AI-powered personal tutors.
Decision support systems in healthcare.
AI for creative tasks (e.g., music or art generation).
17. Task-Oriented Agents
Description: Focused on specific, well-defined tasks.
Use Cases:
Chatbots for customer support (e.g., handling FAQs, resolving issues).
Personal assistants like Siri or Alexa for managing calendars, reminders, and basic queries.
E-commerce recommendation agents for personalized shopping suggestions.
18. Reactive Agents
Description: Respond directly to stimuli from their environment without internal memory or planning.
Use Cases::
Game-playing bots in real-time strategy games.
Automated navigation tools (e.g., robot vacuum cleaners or drones).
19. Learning Agents
Description: Learn and improve over time by interacting with the environment.
Use Cases:
