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