Perhaps you should try some spelling variations:
fractional programacao » operacional programacao (Expand search), fractional programming (Expand search), function programacao (Expand search)
decrease processes » disease processes (Expand search), decay processes (Expand search)
decrease decrease » decrease release (Expand search), disease decreases (Expand search), decrease sucrose (Expand search)
method fractional » method variational (Expand search)
decrease at » decrease akt (Expand search), decrease and (Expand search), decrease in (Expand search)
at decrease » rate decrease (Expand search), that decrease (Expand search), and decrease (Expand search)
python abc » python and (Expand search), python api (Expand search), python c (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 at decrease decrease processes ) OR ( python abc method fractional programacao ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease at decrease decrease processes ) OR ( python abc method fractional programacao ))*.
