9. Agents based on FOL 1. First Order Logic (FOL)<br />

Definition (continued)<br />

Formula: L-formulae ϕ are also defined inductively:<br />

1 if P k is a k-dimensional predicate symbol from L and<br />

t 1 , . . . ,t k are L-terms then P k (t 1 , . . . , t k ) is an L-formula<br />

2 for all L-formulae ϕ is (¬ϕ) a L-formula<br />

3 for all L-formulae ϕ and ψ are (ϕ ∧ ψ) and (ϕ ∨ ψ)<br />

L-formulae.<br />

4 if x is a variable and ϕ a L-formula then are (∃ x ϕ) and<br />

(∀ x ϕ) L-formulae.<br />
