Detailed Description

template<typename numtype>
struct CMR::LP::DualGroup< numtype >

Class template for storing dual LP solutions.

Template Parameters

numtype

the number type used for the vectors/pi values.

Constructor & Destructor Documentation

template<typename numtype >

CMR::LP::DualGroup< numtype >::DualGroup	(	bool	remove_neg,
		const LP::Relaxation &	relax,
		const Sep::ExternalCuts &	ext_cuts
	)

Construct DualGroup from a Relaxation and HyperGraph collection.

Construct a DualGroup by querying the LP solver for dual values and using the collection of cuts, cliques, and teeth to generate clique multiplicities and node pi estimates.

Template Parameters

numtype

the numeric representation. Should be one of double or util::Fixed64.

Parameters

remove_neg	if true, negative dual values will be replaced with zero.
relax	the Relaxation which will be used to grab node and cut pi's.
ext_cuts	the HyperGraph list of cuts in the Relaxation.
