partitioning programs. It includes KaFFPa (Karlsruhe Fast Flow
Partitioner), which is a multilevel graph partitioning algorithm,

which is a parallel evolutionary algorithm that uses KaFFPa to
provide combine and mutation operations, as well as KaBaPE which
extends the evolutionary algorithm. Moreover, specialized
techniques are included to partition road networks (Buffoon), to
output a vertex separator from a given partition or techniques
geared towards efficient partitioning of social networks.
