Perhaps you should try some spelling variations:
algorithm python » algorithm within (Expand Search), algorithms within (Expand Search), algorithm both (Expand Search)
waning function » learning functions (Expand Search), hardening function (Expand Search), hearing functions (Expand Search)
python function » protein function (Expand Search)
using function » using functional (Expand Search), sine function (Expand Search), lung function (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: "(( algorithm ((using function) OR (waning function)) ) OR ( algorithm python function ))~".
• Adding a wildcard symbol may retrieve word variants: (( algorithm ((using function) OR (waning function)) ) OR ( algorithm python function ))*.
