9. Agents based on FOL 4. (Con-)Golog<br />

Test actions:<br />

DO(φ?, s, s ′ ) = φ[s] ∧ s . = s ′<br />

Here φ stands for a situation calculus formula<br />

with all situation arguments suppressed. φ[s]<br />

stands for the arguments restored: if φ is<br />

∀x (ontable(x) ∧ ¬on(x, A)) then φ[s] is the<br />

formula<br />

∀x (ontable(x, s) ∧ ¬on(x, A, s)).<br />

If φ is ∃x (on(x, favorite_block(nils))) then<br />

φ[s] is the formula<br />

∃x (on(x, favorite_block(nils, s), s)).
