  "Description": "Utilize an orthogonality constrained optimization\nalgorithm of Wen & Yin (2013) <DOI:10.1007/s10107-012-0584-1>\nto solve a variety of dimension reduction problems in the\nsemiparametric framework, such as Ma & Zhu (2012)\n<DOI:10.1080/01621459.2011.646925>, Ma & Zhu (2013)\n<DOI:10.1214/12-AOS1072>, Sun, Zhu, Wang & Zeng (2017)\n<doi:10.48550/arXiv.1704.05046> and Zhou & Zhu (2018+)\n<doi:10.48550/arXiv.1802.06156>. It also serves as a general\npurpose optimization solver for problems with orthogonality\nconstraints. Parallel computing for approximating the gradient\nis enabled through `OpenMP'.",
