===== 2. Agent: Active Actor (Autonomy + Intentionality) =====

An agent is a specialized type of actor that not only undergoes change but also has autonomy and intentionality. Agents are active participants in a system and can decide to change their state based on internal goals, beliefs, and plans. They make decisions and adapt based on feedback from the environment or other agents.

====== Key Properties of an Agent: ======
* Autonomy: The agent can act independently and self-direct its behavior.
* Intentionality: The agent’s change is guided by internal goals, beliefs, desires, or policies.
* Learning and adaptation: Agents can learn from past experiences and adjust their behavior accordingly. This allows for goal-directed behavior over time (e.g., reinforcement learning).
* Internal state modification: Agents may modify their internal state based on their interactions with the environment or other agents.

Example:
* A robot is an agent because it can learn to navigate a maze by making decisions based on sensors, goals, and past experiences.

Mathematically:

St+1=f(St,Ωt,Rt,Πt)S_{t+1} = f(S_t, \Omega_t, R_t, \Pi_t)St+1=f(St,Ωt,Rt,Πt)
Where Πt\Pi_tΠt represents the policy or decision-making function of the agent.
