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

Definition (continued)<br />

We write:<br />

A |= ϕ[ϱ] for A(ϕ) = true: A is a model for ϕ with<br />

respect to ϱ.<br />

If ϕ does not contain free variables, then A |= ϕ[ϱ] is<br />

independently from ϱ. We simply suppress ϱ.<br />

If there is at least one model for ϕ , then ϕ is called<br />

satisfiable or consistent.
