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

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: "((((\"_ estimation algorithms\") OR (\"qoe estimation algorithm\"))) OR (\"qoe optimized algorithms\"))~".
• Removing quotes may allow a broader search: (((( _ estimation algorithms ) OR ( qoe estimation algorithm ))) OR ( qoe optimized algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (((("_ estimation algorithms") OR ("qoe estimation algorithm"))) OR ("qoe optimized algorithms"))*.
