Perhaps you should try some spelling variations:
counting function » coupling functions (Expand search), coping function (Expand search), counting education (Expand search)
code complexity » case complexity (Expand search), care complexity (Expand search), the complexity (Expand search)
function python » function path (Expand search), function protein (Expand search), function plasmon (Expand search)
using counting » using accounting (Expand search), using cutting (Expand search), using coupling (Expand search)
code code » code cdc (Expand search), code 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: "(( code code complexity control program ) OR ( using counting function python programming ))~".
• Adding a wildcard symbol may retrieve word variants: (( code code complexity control program ) OR ( using counting function python programming ))*.
