9. Agents based on FOL 3. Successor State Axioms<br />

A Solution to the Frame Problem?<br />

Where do the successor state axioms come<br />

from?<br />

We have to ask: Which fluents stay<br />

invariant?<br />

relational fluent:<br />

¬broken(x, s) ∧ (x ≠ y ∨ ¬fragile(x, s)) −→<br />

¬broken(x, do(drop(r, y), s))<br />

functional fluent: color(x, s) . = c −→<br />

color(x, do(drop(r, y), s)) . = c<br />

How many of such axioms do we need?
