Keyword and GAMS Search

This page provides a search of keywords, GAMS classification codes and names of routines. The results from the search relate to routines and chapters with a short description of its purpose, a list of related keywords and a list of related GAMS classification names.

Keywords, GAMS classification names and names of routines may be added to the box below. Please use the TAB, arrow keys or the mouse to complete words from the drop down menu. Multiple keywords must be separated by a character space.

The ENTER key will return a list of related routines; further keywords may be added, separated with white space, and ENTER re-pressed to refine the search list.

Please see the notes below for further advice.

Notes

• Keywords are restricted to lowercase ASCII letters, digits, ', - and _. For example, to search for Padé, use pade. (Search results show keywords with richer formatting.)
• An asterisk, *, acts as a wildcard; so gauss-* matches gauss-kronrod, gauss-newton, etc.
• Indexed keywords include the GAMS classification scheme. For example, g2e corresponding to the GAMS heirarchy: G = optimization; G2 = constrained ; G2e = quadratic programming.
• Each routine in a search result lists associated GAMS classification names; hovering over each of these reveals its full GAMS definition.
• Routine names are indexed by long and short names, and, where applicable, BLAS and LAPACK names. For example, the keyword dgesv returns, among other details, the names f07aaf and nagf_lapack_dgesv and DGESV.
• The Kwic index url ending in a query such as ?q=real+eigenvalue will return the search page resulting from the search box initialized with real eigenvalue. You can update the url of the current page to reflect the current search by clicking the 'Update URL' button above the search box.
