Algorithm 2 Verify whether it is possible to merge a leaf cluster ${\mathcal{LC}}_i$ to $\mathcal{IC}$.
1:	MergeCluster( ${\mathcal{LC}}_i$, $\mathcal{IC}$, Oi)
2:	if CollidingClusters( ${\mathcal{LC}}_i$, ${\mathcal{LC}}_{i-\mathit{1}}$, Oi) == FALSE then
3:	return FALSE.
4:	if $\{B_{\mathcal{IC}}–B_{i–1}\}\cap B_i\ne \mathit{NULL}$ then
5:	return FALSE. // BVs overlap
6:	return TRUE.
