Perhaps you should try some spelling variations:
tone complexity » the complexity (Expand search), code complexity (Expand search), time complexity (Expand search)
rotating method » rotations method (Expand search), coating method (Expand search), rating method (Expand search)
using rotating » in rotating (Expand search)
method python » method method (Expand search), python python (Expand search)
coder » poder (Expand search), codes (Expand search), coded (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 tone complexity control program ) OR ( using rotating method python programming ))~".
• Adding a wildcard symbol may retrieve word variants: (( coder tone complexity control program ) OR ( using rotating method python programming ))*.
