◆ ComputeGradientSearch()

static VectorValues gtsam::DeltaImpl::ComputeGradientSearch	(	const VectorValues &	gradAtZero,
		const VectorValues &	RgProd
	)

static

Compute the gradient-search point. Only used in Dogleg.

static size_t gtsam::DeltaImpl::UpdateGaussNewtonDelta	(	const ISAM2::Roots &	roots,
		const KeySet &	replacedKeys,
		double	wildfireThreshold,
		VectorValues *	delta
	)

static

Update the Newton's method step point, using wildfire

static size_t gtsam::DeltaImpl::UpdateRgProd	(	const ISAM2::Roots &	roots,
		const KeySet &	replacedKeys,
		const VectorValues &	gradAtZero,
		VectorValues *	RgProd
	)

static

Update the RgProd (R*g) incrementally taking into account which variables have been recalculated in replacedKeys. Only used in Dogleg.
