Detailed Description

template<class LocalOrdinal = int, class GlobalOrdinal = LocalOrdinal, class Node = KokkosClassic::DefaultNode::DefaultNodeType>
class MueLu::InterfaceAggregationAlgorithm< LocalOrdinal, GlobalOrdinal, Node >

Algorithm for coarsening a graph with uncoupled aggregation. creates aggregates along an interface using specified root nodes.

Idea

The user can mark some nodes as INTERFACE to build aggregates across an interface. This can be very useful for certain applications. We build aggregates for nodes with the state INTERFACE. Then, the state is changed to AGGREGATED. The InterfaceAggregationAlgorithm should run before the Phase1AggregationAlgorithm.
