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 algorithms" » "qoe optimized algorithms", "qoe optimization algorithms"
"_ optimized algorithm" » "_ optimized algorithms"

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

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