Why using linear least square when doing transformation estimation ?What's the advantage? Do you publish any paper? #1

In my opinion, LLS do not have the iterative procedure involved in non-linear optimization(NLO) methods such as GN and LM so LLS should be a bit faster. Besides, when the rotation angle is relatively small, LLS's result would be close to NLO's. We haven't published any paper yet. A reference is: François Pomerleau, Francis Colas and Roland Siegwart (2015), "A Review of Point Cloud Registration Algorithms for Mobile Robotics". Thanks.
