Expand description

Minimise ½‖r(p)‖² over the free parameters of problem with Levenberg–Marquardt.

On return the problem holds the best parameters found. Deterministic: no RNG, no clock — identical inputs give identical iterates — given a fixed faer parallelism policy; spectrafit-solver::fit sets Par::Seq for the whole fit, and a caller that leaves faer on its default (potentially multi-threaded) policy can see floating-point summation-order differences across runs.
