Perhaps you should try some spelling variations:
"qoe estimation algorithms" » "qoe optimization algorithms", "qoe optimisation algorithm", "qoe approximation algorithms", "pose estimation algorithms", "_ estimation algorithms", "cover estimations algorithms"
"qoe optimized algorithms" » "qoe optimized algorithm", "qoe optimizer algorithms", "qoe optimization algorithms", "_ optimized algorithms"
"qoe estimation algorithm" » "pose estimation algorithm", "_ estimation algorithm", "cover estimations algorithm"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("qoe optimized algorithms") or ((("qoe estimation algorithms") OR ("qoe estimation algorithm"))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("qoe optimized algorithms") OR ((("qoe estimation algorithms") OR ("qoe estimation algorithm")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"qoe optimized algorithms\") or (((\"qoe estimation algorithms\") OR (\"qoe estimation algorithm\"))))".
• Removing quotes may allow a broader search: (( qoe optimized algorithms ) or ((( qoe estimation algorithms ) OR ( qoe estimation algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("qoe optimized algorithms") or ((("qoe estimation algorithms") OR ("qoe estimation algorithm"))))*.
