New cost function:
$c(t_{i},n_{j})=\alpha \cdot ({\text{lcg}}(n_{j})+bw_{req,tot}(n_{j})+RR(n_{j}))+\beta \cdot \sum _{k\in T_{conn,mp}}{d(k)\cdot {\text{vol}}(k)}$
where
${\text{lcg}}(n)={\frac {1}{\#tiles_{clu}}}\sum _{l\in N}d(n,l)$
d(n,l) is the manhattan distance between tiles n and l

$O(m\cdot \log m+n\cdot m)$

$O(\ {\frac {n!}{(n-m)!}}\ )$
