double Acts::AnnealingUtility::getWeight	(	State &	state,
		double	chi2,
		const std::vector< double > &	allChi2
	)		const

Weight access.

Parameters

state	The state object
chi2	Chi^2 for e.g. current track, i.e. compatibility of track to current vertex candidate
allChi2	Vector of all chi^2 values, i.e. e.g. compatibilities of current track to all vertices it is currently attached to

Returns

Calculated weight according to Eq.(5.46) in Ref.(1)
