Add AccurateRNorm

Composing two-argument functions for variadic Jet inputs can produce
invalid derivatives because intermediate results do not preserve the
full derivative relationship. Introduce overflow and underflow safe
Euclidean reciprocal norm with variadic overloads. The Jet overloads
compute derivatives from all arguments using the complete chain rule.

Ceres Solver

Ceres Solver is an open source C++ library for modeling and solving large, complicated optimization problems. It is a feature rich, mature and performant library which has been used in production at Google since 2010. Ceres Solver can solve two kinds of problems.

  1. Non-linear Least Squares problems with bounds constraints.
  2. General unconstrained optimization problems.

Please see ceres-solver.org for more information.
