+Chaco contains a wide variety of algorithms and options, many of which were invented by the authors. Some of the algorithms exploit the geometry of the mesh, others its local connectivity or its global structure as captured by eigenvectors of a related matrix. These methods can be mixed and matched in several ways, and combinations often prove to be more effective than any single technique in isolation. All these algorithms are accessed via a simple user interface, or a call from other software. Innovations in Chaco include # Development of multilevel graph partitioning. This widely imitated approach has become the premiere algorithm combining very high quality with short calculation times. # Extension of spectral partitioning to enable the use of 2 or 3 Laplacian eigenvectors to quadrisect of octasect a graph. # Highly efficient and robust eigensolvers for use with spectral graph algorithms. # Generalization of the Kernighan-Lin/Fiduccia-Mattheyses algorithm to handle weighted grap
 hs, arbitrary number of sets and lazy initiation. # Development of skewed partitioning to improve the mapping of a graph onto a target parallel architecture. # Various post-processing options to improve partitions in a number of ways.
