gtsam::MetisIndex Class Reference

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.

Standard Constructors

Member Function Documentation

◆ augment()

template<class FACTOR >
void gtsam::MetisIndex::augment ( const FactorGraph< FACTOR > &  factors)

Augment the variable index with new factors.

This can be used when solving problems incrementally.
