Agent

An agent consists of multiple components:

• Sensors: Sensors for perceiving the “world” - they produce perception sequences
• Actuators: Actuators for acting
• Agent function: The agent function $f:{\mathcal{P}}^{\ast }\to A$ maps from percept histories, i.e., sequences $p_1,p_2,\dots ,pn$ of percepts $p_i$, $n\ge 0$, to actions. Note that $f$ should be computable
• Agent program: The agent program runs on the physical architecture to produce $f$.
