Perhaps you should try some spelling variations:
functions python » functions methods (Expand search), functions 4th (Expand search), finitos python (Expand search)
cost functions » cost function (Expand search)
coder action » border action (Expand search), under action (Expand search), power action (Expand search)
action using » reaction using (Expand search), section using (Expand search), suction using (Expand search)
using python » usando python (Expand search), in python (Expand search)
using cost » using cosmo (Expand search), using cone (Expand search), using co (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: "(( coder action using python programming ) OR ( using cost functions python programming ))~".
• Adding a wildcard symbol may retrieve word variants: (( coder action using python programming ) OR ( using cost functions python programming ))*.
