There are a number of different ways of solving this problem, each giving rise to a different concrete trust-region algorithm. Currently Ceres, implements two trust-region algorithms - Levenberg-Marquardt and
Dogleg
.

ourselves to moving along the direction of the gradient.
Dogleg
methods finds a vector $\Delta x$ defined by $\Delta

and finds the point farthest along this line shaped like a
dogleg

The key advantage of the
Dogleg
over Levenberg Marquardt is that if the step computation for a particular choice of $\mu$ does not result in sufficient decrease in the value of the objective function, Levenberg-Marquardt solves the linear approximation from scratch with a smaller value of $\mu$.
Dogleg
on the other hand, only needs to compute the interpolation between the Gauss-Newton and the Cauchy vectors, as neither of them depend on the value of $\mu$.

The
Dogleg
method can only be used with the exact factorization based linear solvers.
437
and \texttt{
DOGLEG
} are the two valid choices.
