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