Perhaps you should try some spelling variations:
variational program » variational problem (Expand search), variational problems (Expand search), adaptational program (Expand search)
without variational » without additional (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)
basin without » basins without (Expand search), brasil without (Expand search), resin without (Expand search)
python basin » python based (Expand search), python api (Expand search), python task (Expand search)
in decrease » in decreased (Expand search), on decrease (Expand search), pain decrease (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 in decrease decrease processes ) OR ( python basin without variational program ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease in decrease decrease processes ) OR ( python basin without variational program ))*.
