\textit{Oh, Consider  an empty article!} embodied agent whose internal state $y \in Y$, sensor inputs $s \in S$ and actuator outputs $a \in A$ vary over time.  You can get started by \textbf{double clicking} this text block and begin editing. You can also click We will define a cognitive interpretation $C$ of the agent as a function which maps  the \textbf{Insert} button below agent's state $y$  to add new block elements. Or you can \textbf{drag a belief $b \in B$, a desire $d \in D$  and drop an image} right onto this text. Happy writing! a fundamental set of immutable assumptions $\phi \in \Phi$. We will require that the assumptions do not vary with the agent's state.  \[ C: Y \Rightarrow (B \times D \times \Phi) \textrm{ where } \\  \forall y_1, y_2 \in Y . C(y_1) = (b_1, d_1, \phi_1) \land C(y_2) = (b_2, d_2, \phi_2) \implies \phi_1 = \phi_2 \]  We will define a model of rationality $M$ as a
