Perhaps you should try some spelling variations:
variational program » variational problem (Expand search), variational problems (Expand search), adaptational program (Expand search)
method variational » methods variational (Expand search), method variations (Expand search), without variational (Expand search)
decrease processes » disease processes (Expand search), defense processes (Expand search), decay processes (Expand search)
decrease decrease » decrease release (Expand search), disease decreases (Expand search), decrease sucrose (Expand search)
decrease the » decreases the (Expand search), decrease in (Expand search), decrease of (Expand search)
the decrease » to decrease (Expand search), and decrease (Expand search)
python in » python and (Expand search), python _ (Expand search), python c (Expand search)
in method » in methods (Expand search), cn method (Expand search)

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease the decrease decrease processes ) OR ( python in method variational program ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease the decrease decrease processes ) OR ( python in method variational program ))*.
