Currently AlphaFastVertexSubstitution only works with InstanceTwoSets. It must be adapted to work with InstanceSameSet as well in order to compare with methods from the literature.
Ideas
Since $f_r$ would become a user $u_r$, it should be allocated to its $\alpha$-neighbors and update $x'$, $r(\cdot)$ and $z(\cdot)$ according to its $\alpha$-th center, because this new assignment could be a better objective function value.
