Perhaps you should try some spelling variations:
tone complexity » the complexity (Expand search), code complexity (Expand search), time complexity (Expand search)
boosting method » costing method (Expand search), costing methods (Expand search), casting method (Expand search)
using boosting » using rotating (Expand search), using boosted (Expand search), using resting (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.

• Removing quotes may allow a broader search: (( coder tone complexity control program ) OR ( using boosting method python programming ))~.
