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.

Constructors
	MetisIndex ()
	Default constructor, creates empty MetisIndex.
template<class FactorGraphType>
	MetisIndex (const FactorGraphType &factorGraph)

Standard API
template<class FactorGraphType>
void	augment (const FactorGraphType &factors)
	Augment the variable index with new factors.
const std::vector< int32_t > &	xadj () const
const std::vector< int32_t > &	adj () const
size_t	nValues () const
Key	intToKey (int32_t value) const

Testable
void	print (const std::string &str="MetisIndex:") const
	print to std::cout

Public Types
typedef std::shared_ptr< MetisIndex >	shared_ptr

Member Function Documentation

augment()

template<class FactorGraphType>

void gtsam::MetisIndex::augment

(

const FactorGraphType &

factors

)

Augment the variable index with new factors.

This can be used when solving problems incrementally.
