This selection provides a list of routines from the NAG Library for solving various mathematical optimization problems ordered by the problem type. It spans across Chapters E04, E05 and H. Please refer to the E04, E05 and H Chapter Introductions for help with the problem type classification, algorithmic details and advice on the selection of the right solver. See the full chapter tables of contents as listed above for additional functionality not listed here, such as file I/O or option setting routines.
