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"
"done optimized algorithms" » "done optimizer algorithms", "done optimization algorithms", "done optimizer algorithmss", "d_ optimized algorithms", "dong optimized algorithms", "don optimized algorithms"
"one optimized algorithm" » "one optimizer algorithms", "_ optimized algorithm"

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

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