  "message": "Allow Solver::Options::max_num_line_search_step_size_iterations \u003d 0.\n\nThis change only affects the TRUST_REGION minimizer and has no effect\non the LINE_SEARCH minimizer.\n\nThis options controls the number of iterations that the line search\nalgorithm performs. The line search algorithm is as the name implies,\nused in the LINE_SEARCH minimizer. It is also used by the TRUST_REGION\nminimizer when solving bounds constrained optimization problems.\n\nIn some bounds constrained problems, it is enough to project each step\nonto the bounds constraints and not perform the line search. This can\nhave a significant impact on runtime. Setting\nSolver::Options::max_num_line_search_step_size_iterations \u003d 0 enables\nthis functionality.\n\nChangchang Wu (ccwu@google.com) came up with the idea for this\nimplementation.\n\nhttps://github.com/ceres-solver/ceres-solver/issues/477\n\nChange-Id: Ifbe0bc5c48eedb2c1231d43cd98e4be7316c0682\n",
