Let $\mathcal{K}$ be a relational Fraïssé class with finitely many relations and a finite constraint set. Suppose that $\mathcal{K}$ satisfies the Ramsey property or has finite sma…

Let $\mathcal{K}$ be a relational Fraïssé class with finitely many relations and a finite constraint set. A constraint set is a finite set of finite structures such that membership…
