Perhaps you should try some spelling variations:
detection algorithm » detection algorithms (Expand search), selection algorithm (Expand search)
optimization based » optimization and (Expand search)
code detection » node detection (Expand search), case detection (Expand search), care detection (Expand search)
using coping » using coding (Expand search), using coupling (Expand search), nursing coping (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 detection algorithm optimization based ) OR ( using coping _ python programming ))~".
• Adding a wildcard symbol may retrieve word variants: (( code detection algorithm optimization based ) OR ( using coping _ python programming ))*.
