Selection of architectures with a multiple domain co-occurrence. (A) Two architectures, A₁, A₂, where A₁ is composed by a double occurrence of domain b. Domains are denoted with different letters, and the same letter code is used in (B) and (C). (B) List of architectures that allow for the selection of A₁ with the objective function F₂, because $F_2(abb)=3$ and $F_2(abc)=2$. (C) List of architectures that allow for the selection of A₂ with the objective function F₄, because $F_4(abb)=2$ and $F_4(abc)=3$. Note that $F_2(abb)=F_2(abc)=2,\hspace{0.17em}{F}_3(abb)=F_3(abc)=3$
