Detailed Description

The MetisIndex class converts a factor graph into the Compressed Sparse Row format for use in METIS algorithms. Specifically, two vectors store the adjacency structure of the graph. It is built from a factor graph prior to elimination, and stores the list of factors that involve each variable.

Constructor & Destructor Documentation

MetisIndex()

gtsam::MetisIndex::MetisIndex ( )

inline

Default constructor, creates empty MetisIndex

Member Function Documentation

augment()

template<class FACTORGRAPH >

void gtsam::MetisIndex::augment

(

const FACTORGRAPH &

factors

)

Augment the variable index with new factors. This can be used when solving problems incrementally.
