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