Perhaps you should try some spelling variations:
"_ estimation algorithms" » "_ optimization algorithms", "_ optimisation algorithm", "_ approximation algorithms"
"qoe optimized algorithm" » "qoe optimized algorithms", "qoe optimizer algorithms", "_ optimized algorithm"
"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: "((((\"qoe optimized algorithm\") OR (\"qoe estimation algorithm\"))) OR (\"_ estimation algorithms\"))~".
• Removing quotes may allow a broader search: (((( qoe optimized algorithm ) OR ( qoe estimation algorithm ))) OR ( _ estimation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (((("qoe optimized algorithm") OR ("qoe estimation algorithm"))) OR ("_ estimation algorithms"))*.
