Perhaps you should try some spelling variations:
improve processes » improve process (Expand search), improving processes (Expand search), improvement processes (Expand search)
decrease improve » decrease income (Expand search), decrease pro (Expand search), decrease sucrose (Expand search)
method python » method method (Expand search), python python (Expand search)
python based » action based (Expand search)
decrease to » decreased to (Expand search), decrease toc (Expand search), decrease the (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 to decrease improve processes ) OR ( python based method python programming ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease to decrease improve processes ) OR ( python based method python programming ))*.
