  While the relevant logic \(\mathbf{R}\) has a proof system more complex than the substructural logics such as linear logic, which lack distribution of (extensional) conjunction over disjunction, its model theory is altogether more simple. A Routley-Meyer model for the relevant logic \(\mathbf{R}\) is comprised of a set of points \(P\) with a three-place relation \(R\) on \(P\). A conditional \(A \rightarrow B\) is evaluated at a world as follows:
