  "message": "Add a lower bound on the regularization constant in LM.\n\nIn some cases the Levenberg-Marquardt can oscillate between,\ntwo values of the regularizer mu. A small value which causes\nthe linear solver to fail and a higher value at which the solver\nmakes progress. This can cause significant wastage of solver\neffort, and mu should just be clamped to some value.\n\nThis CL provides this setting as Solver::Options::min_mu,\nand updates the documentation to reflect this.\n",
