... A naive way to perform VN assignment is to treat Vnode mapping and Vlink mapping as two independent sub-problems and solve them sequentially. Cons: the optimality of Vnode mapping and optimality of Vlink mapping cannot be achieved at the same time via the naive solution. e.g., two ways of embedding ...
