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

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("qoe estimation algorithms") OR ((("qoe optimized algorithms") OR ("qoe optimizer algorithms"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"qoe estimation algorithms\") OR (((\"qoe optimized algorithms\") OR (\"qoe optimizer algorithms\"))))".
• Removing quotes may allow a broader search: (( qoe estimation algorithms ) OR ((( qoe optimized algorithms ) OR ( qoe optimizer algorithms )))).
• Adding a wildcard symbol may retrieve word variants: (("qoe estimation algorithms") OR ((("qoe optimized algorithms") OR ("qoe optimizer algorithms"))))*.
