**5.4 Merging** *pivots* **and** *targets*

After *pivots* and *targets* have been selected, the merging procedure, i.e.,

$$
\textit{pivot}\_{s+1} \leftarrow \textit{pivot}\_{s} \cup \textit{target}\_{s} \tag{27}
$$

is performed. This procedure means that every cluster in *targets* is included in *pivots*+1. Then *pivots* and *targets* are removed from *UEXs* and *RDYs*. After this merging step has been performed, clusters satisfying requirements for *RDYs*+1(in eq. (26)) are included in *RDYs*+1. Furthermore, every cluster's *LV* value is updated for selecting *pivots*+<sup>1</sup> and *targets*+<sup>1</sup> before the next merging step.
