Perhaps you should try some spelling variations:
code complexity » case complexity (Expand search), care complexity (Expand search), the complexity (Expand search)
boosting vector » poynting vector (Expand search), commuting vector (Expand search), rotating vectors (Expand search)
using boosting » using rotating (Expand search), using boosted (Expand search), using resting (Expand search)
vector python » vector pathogen (Expand search), vector method (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.

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