◆ extraReelimKeys

boost::optional<FastList<Key> > gtsam::ISAM2UpdateParams::extraReelimKeys {boost::none}

An optional set of nonlinear keys that iSAM2 will re-eliminate, regardless of the size of the linear delta.

This allows the provided keys to be reordered.

bool gtsam::ISAM2UpdateParams::forceFullSolve {false}

By default, iSAM2 uses a wildfire update scheme that stops updating when the deltas become too small down in the tree.

This flagg forces a full solve instead.

boost::optional<FastMap<FactorIndex, KeySet> > gtsam::ISAM2UpdateParams::newAffectedKeys {boost::none}

An optional set of new Keys that are now affected by factors, indexed by factor indices (as returned by ISAM2::update()).

Use when working with smart factors. For example:

Timestamp i: ISAM2::update() called with a new smart factor depending on Keys X(0) and X(1). It returns that the factor index for the new smart factor (inside ISAM2) is 13.
Timestamp i+1: The same smart factor has been augmented to now also depend on Keys X(2), X(3). Next call to ISAM2::update() must include its newAffectedKeys field with the map 13 -> {X(2), X(3)}.
