  "Description": "Some accelerated three-term conjugate gradient algorithms\nimplemented purely in R with the same user interface as\noptim(). The search directions and acceleration scheme are\ndescribed in Andrei, N. (2013) <doi:10.1016/j.amc.2012.11.097>,\nAndrei, N. (2013) <doi:10.1016/j.cam.2012.10.002>, and Andrei,\nN (2015) <doi:10.1007/s11075-014-9845-9>. Line search is done\nby a hybrid algorithm incorporating the ideas in Oliveia and\nTakahashi (2020) <doi:10.1145/3423597> and More and Thuente\n(1994) <doi:10.1145/192115.192132>.",
