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"))))*.
