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