<h2>

<a name="CYCLIC"></a>Cyclic</h2>
|
||
|
|
A simple partitioner based on cyclic (round robin) partitioning of the objects.
|
||
|
|
It uses neither geometry nor connectivity (graph/hypergraph), so it requires very few query functions. This method currently does not take into account target part sizes nor weights, so the parts may not be balanced in this case!
|
||
|
|
<br>
|
||
|
|
Note that the partitioning is cyclic with respect to the local order of objects, and NOT by the global ids.
