Perhaps you should try some spelling variations:
nonlinear programming » linear programming (Expand search)
degenerate nonlinear » general nonlinear (Expand search), degenerate quasilinear (Expand search)
or degenerate » of degenerate (Expand search), on degenerate (Expand search), non degenerate (Expand search)
in decrease » in decreased (Expand search), pain decrease (Expand search), and decrease (Expand search)
decrease on » decrease of (Expand search), decrease and (Expand search), decrease toc (Expand search)
on decrease » on decreased (Expand search), of decrease (Expand search), or decrease (Expand search)
decrease or » decrease of (Expand search), decrease pro (Expand search), decrease toc (Expand search)

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (( decrease in decrease on decrease ) OR ( decrease OR degenerate nonlinear programming ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease in decrease on decrease ) OR ( decrease or degenerate nonlinear programming ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease in decrease on decrease ) OR ( decrease or degenerate nonlinear programming ))*.
